Hackett, Sr, President Summary: Safe Environmental Solutions, Inc. conducted an indoor air quality assessment at the Hale-Dale Middle School Facility on May 22, 201?. The purpose of this assessment was to identify any potential IAQ items that may be having a negative effect on the facitity's Indoor Air Quality. Based on my knowledge of this facility and from my initial facility walk thru and information during conversations with facility the Facility Director and custodian personal, and conferring with my laboratory representative, screening was conducted for Airborne Mold Spores, Carbon Monoxide, Carbon Dioxide, Temperature, Relative Humidity, and USEPA TO. 15 Volatile Organic Compounds samples. Samples were analyzed by the following laboratories: Mold analysis was conducted by Northeast Laboratories, located in Winslow, Maine and the TO 15 VOCs were analyzed by EMSL Analytical in Cinnaminson, New Jersey. In addition, we conducted a visual evaluation of the rooms and conducted visual inspections within the wall cavities in rooms 208 8; 210 utilizing a borescope. Results: Table 1.1 Non-viable Mold Spore Room 219 110 Basidospores Room 210 1200 Ascospores Room 208 480 Ascopores Table 1.2 Surface Tape lift Sample I Room 210 Window A sheetrock Stachybotrys-sp Carbon Monoxide, Carbon Dioxide, Temperature. Relative Humidity Data logging results did not identify any high levels of carbon monoxide. Levels of carbon dioxide, temperature, and relative were identified at levels considered ?typical" for this time of year with seasonal influences. One must also keep in mind that the testing was done without the typical occupant levels, the identified levels are expected to be higher with typical student occupant load. CARBON MONOXIDE Carbon monoxide (CO) sources are usually traced to the ingress of the vehicle exhaust fumes or fumes leaking from poorly ventilated combustion sources, furnaces, and boilers. Carbon monoxide is a colorless, odorless gas, and because contamination from CO gas is insidious, preventative measures should be taken to ensure that here is no ingress of CO gas into the indoor environment. indoor air quality criteria recommend that carbon monoxide levels remain below 9.0 parts per million (ppm) throughout the work day. Occupational Safety and Health Administration has established an upper acceptable limit of 35 ppm. Outdoor level was found at .5 upon arrival, indoor levels were all found at 0.0 ppm. CARBON DIOXIDE When (302 levels increase indoors, many people may experience discomfort, headaches. tiredness, and general lethargy. It is generally accepted that it is not a lack of oxygen, nor even the build-up of C02 itself causing the problem, but the sum of all indoor air contaminants that are trapped in the indoor environment at the same time due to lack of proper ventilation. Thus the value of (302 is used as a surrogate indicator of the effectiveness of overall ventilation is recognized. The Standard 62.1-2010 does not set an upper limit for Carbon Dioxide (002) but recommends that levels be maintained at no more than T00 above outdoor levels. Typically, outdoor ambient air concentrations of 002 can range from 350 to 450 depending on such variables as temperature inversions, vehicle traffic, or other combustion sources. Outdoor sample level was found at 510 upon arrival and the inside levels ranged from 546 (Room 210), 708 (Room 208} and 845 (Room 219) all well within recommendations. TEMPERATURE RELATIVE HUMIDITY Standard 55-2010, Thermal Environmental Conditions for Human Occupancy. recommends that temperatures during the winter months be maintained between - and during the summer months between - 79F and recommends that Relative Humidity range between 30% - 40% in winter months and 40% - 50 ?it in summer months. On average, humidity levels of 30% - 60% are generally acceptable for all seasons, dependent on the actual interior temperature and type of clothing worn by occupants. Temperature was within limits during the monitoring ranging from 72.4 74.1 in interior locations. Relative Humidity levels were within recommended and typical in our state during this time of year interior levels ranging from 35.8% 41% Results Interpretation Phase ?Temperature was found within the expected range for this type of setting during the present season. Relative Humidity was found ?typical" levels during this time of year with seasonal influences. Carbon Dioxide was found within expected levels based on time of year, Carbon monoxide was found within current industry recommendations. No ?Red flags" were raised with this testing. Non-viable Mold Spore and Particulate Sample results did not identify any elevationlampli?cations in areas sampled. Levels were considered "Typical" indoor air levels during this time of year. Room 210 was found higher than the other interior sample but still less than the outdoors with the same types of mold identified. No problematic, pathogenic, andior toxigenic types of mold were identified in the interior air. The tape sample collected from the wall cavity in Room 210 did identify a Zero Tolerant mold type "Stachybotrys so". Our borescope visual did confirm that it appears to be scattered within the wall cavity under the window. This specie requires a prolong moisture source to flourish it typically takes up to 14 days to grow which may indicate a reoccurring The wall cavity in Room 208 was built differently and had a poly vapor barrier system installed and no evidene of water and/or mold was seen. Volatile organic compounds (Specific individual results are in the ANAL DA TA section in this report) Levels and compounds identified are not alarming most compounds were found in the outdoor air. Currently, there is no enforceable levels for VOC's hOWever, there are many organizations that have recommendations based on ?typical" indoor levels for homes and schools. Most enforceable levels are based on OSHA which is typically over an B-hr. works day, in a industrial setting. These samples were collected over a 24-hr. period. For the most part the levels found in the interior samples were very comparable between rooms screened. it must be noted that in the "complaint" rooms one (1) VOC identified in Room 210 and two (2) two VOC's were identified in Room 208 that were higher than the ?typical? Residential recommendations. Levels in the "non-complaint" comparison Room 219 had the greatest Total VOC (TVOC) level and the majority of were higher in that room than the complaint areas. All VOC's identified were also identified in the outdoor air as well. Looking at the provided potential sources of a lot of the identified compounds can be, not only sources from the facility, but can also be from items brought from home. The IAQ-index, The GREEN standard for Healthier Environments, recommends and categorizes the following levels, research suggests these recommended levels are low. You will find these recommendations within this report. Recommendations Based on the Air sampling conducted we make the following specific recommendations. 1. Conduct mold remediation of the wall below the window using environmental controls in a negative pressure enclosure by appropriate trained individuals. 2. Conduct post remediation sampling to assist in demonstrating the no-cross contamination had occurred. I have provided some information on potential sources of compounds identified during this assessment. As well as a comparison chart of compounds and levels identified. Please keep in mind that this testing is a ?snap-shot" in time levels and compounds are expected to change with outside influences. Continue with you ?Proactive" Indoor Air Quality Program. Please share this report, in it?s entirety to any treating physician for their professional input. Levels and compounds identified should not effect the ?normal" non- sensitized population. lmmunocompromised individuals may be more sensitive to levels. As always, we appreciate the opportunity to assist you and your school with your indoor air quality needs.

This is largely due to the fact that there is an extremely wide range of individual human sensitivity to these agents. BacteriaiFungi are found in all environments, however, the levels and varieties in indoor environments play a critical role in IAQ. In general, the population found indoors should be quantitatively lower, although similar to outdoor levels. Porous building materials are environments which are conducive to microbial growth, especially when not properly maintained. BacteriaiFungi require moisture and a nutrient source in order to flourish in an indoor environment. These "Amplification" sites are commonly found in water-damaged materials or in areas susceptible to water or moisture infiltration. Aggressive maintenance practices and routine cleaning will aid in the reduction of nutrient sources for microorganisms and contribute significantiy to preserving and maintaining good indoor air quality. Exposure to elevated levels of bacteria and fungi in indoor air can be problematic to building occupants. such as upper respiratory distress, fatigue, general malaise, irritated eyes, nose, and throat are typical complaints. When determining the health risks associated with bioaerosols, it is important to keep in mind that the colony count alone is not the only determining factor. The species of organism(s} identified is sometimes more important than the colony count (number of organisms). Additionally, extreme high levels of fungi andior bacteria may effect the accuracy of enumeration and identification due to over-growth on sampling media. Pathogenic andior toxic organisms can produce health concerns even when identified in small quantities, where ill-health have been reported, or where immuno-compromised individuals may be susceptible. Pathogenic andior toxic organisms should be maintained at the lowest feasibie levels. The vated presence of certain fungai pathogens g. Sp. or certain toxic fungi g. Stachybotiys chartarum) is considered to be unacceptabie. The presence of certain pathogenic bacteria Pseudomonas aeruginosa and Staphylococcus aureus) should be evaluated carefuliy as well. Cheetomium, Fusarium, Stacnybotrys, or Tricnoderma mold species are zero tolerance organisms for the indoor environment as they have the to produce mycotoxins and microbial volatile organic compounds (mvoc?s) and can seriousiy compromise a building andior the health of occupants. These effects for human health can be worse for immune compromised persons (such as those with HIV, the elderly, terminally or seriously ill patients (cancer patients), persons with pre-existing conditions or asthma, and the very young} The analytical data is reviewed to identify specific bacteria or fungi, which may be pathogenic. This evaluation is as important as determining the number of colonies on the media. The colonies developed are not necessarily the most prevalent Species, and the results reflect only those microbes for which the media and incubation conditions are most suitable. Levels of airborne microbes in a conducive environment can fluctuate greatly, even over short periods of time. Allergic responses can be experienced by susceptible individuals exposed to organisms (common, nonpathogenic andior toxic moldsibacteria) in elevated levels. The dominance of a single species may indicate indoor growth, whereas the presence of mixed bacterial species may reflect intrusion of outdoor air or shedding from building occupants. Actinomycetes (especially thermophilic ones) are rare in buildings and outdoors. Therefore, the presence of antinomycetes indoors may be considered an indication of an indoor source. Although there are no regulatory, enforceable levels of mold and/or bacteria there are numerous guidance documents suggesting what may be considered ?normal" levels in a facility without active mold growth.

A General Note on Fungi in Indoor Environments: The information contained in this document is a compilation of information available from various texts, compendia and research literature. The availability of information is often dependent on the types and amount of work that has been done with any particular fungus, and as such there may be substantial gaps in the information on many fungi. The fact that toxins have not been found in a particular fungus does not necessarily mean that toxins are not produced. Also, toxigenic fungi such as Stachybotrys will not always produce toxin since the types and amounts of substances produced generally depend on the environmental conditions present and particularly on the growth substrate. In general, investigators should always consider that fungi growing indoors will be potentially allergenic and to some extent toxigeic. Growth indoors is never a normal or desirable circumstance, and should always be remediated as soon as possible. Precautions taken concerning exposure and remediation should not be based solely on the types of fungi present, but should be based on an overall consideration of the types of fungi present, the extent of contamination and the potential for occupant exposure. Moreover, this guide is not meant to be all-inciusive, and many other types of fungi may be encountered in aerosol and bulk samples. Please feel free to call the laboratory if you should have any questions on these or any other fungi. 2. Fungi Commonly Observed in MO Investigations Absidia sp. - A Zygomycete fungus. This fungus has a worldwide distribution and is principally found in soil and decaying vegetation. Reported to be allergenic. Absio'ia coiymbifera is recognized as an opportunistic pathogen, causing zygomycosis involving the lungs, skin, meninges, and kidneys. Acremonium sp. (Cephaiosporium sp.) - A common and widespread soil fungus. Generally requires very wet conditions for growth. Reported to be allergenic as well as a cause of hypersensitivity pneumonitis. It can produce a trichothecene toxin which is toxic if ingested. It also produces cephalosporins. It was the primary fungus identi?ed in at least two houses where the occupant complaints were nausea, vomiting and diarrhea. In an immunocompromised individual it can cause onychomycosis and more rarely keratitis, endophthalmitis, endocarditis, and meningitis. Alternaria sp. - Outdoors it may be isolated from samples of soil, seeds and plants, where it is very common. It is often found in carpets, textiles, and on horizontal surfaces in building interiors. Often found on window frames. A very common allergen, it has also been associated with hypersensitivity pneumonitis. its large spore size, 20 - 200 microns in length and 7? - 18 microns in width, suggests that the spores from this fungi will deposited in the nose, mouth and upper respiratory tract. Aitemaria aiternata is capable of producing tenuazonic acid, alternariol, altertoxin and other toxic metabolites which may be associated with disease in humans or animals. Occasionally an agent of onychomycosis, ulcerated cutaneous infection and chronic sinusitis, principally in the immunocompromised patient. Ascomycetes This is a large group of fungi with more than 3,000 genera and species. Very widespread and common. they are principally saprophytes and plant pathogens. White some grow and sporulate in culture (eg. Chaetornium), spores are often very slow to develop and some strict piant pathogens are only able to grow in their host plants. In terms of indoor air quality this group is very poorly studied. Their spores are likely to be allergenic and with such a vast number of genera and species, metabolites are likely produced that are toxic to some extent. This group also includes the sexual forms of many fungi that are known more commonly by their asexual forms, such as Penicillium and Aspergillus. The most common sexual forms of Penicillium are Talaromyces and Eupenicillium, while the most common sexual forms of Aspergillus are Eurotium and Emericella. Aspergillus sp. Widespread and commonly encountered, they are found principally in soil and decomposing plant material. They are able to grow well indoors on a wide range of substrates. Water requirements vary with species, but some Xerophilic species require relativeiy drier conditions. Known to be allergenic. Many species produce mycotoxins which may be associated with disease in humans and other animals. Toxin production is dependent on the species or a strain within a species and on the food source for the fungus. Some of these toxins have been found to be carcinogenic in animal species. Several toxins are considered potential human carcinogens. Common cause of extrinsic asthma (immediate-type hypersensitivity: type I). Also capable of causing Type hypersensitivity pneumonitis. Approximately 20 species are currently recognized as opportunistic pathogens, causing nasal sinus lesions, respiratory and ear infections as well as invasive, systemic infections. Aspergillus fumigatus is the most commonly implicated species, followed by A. flavus and A. niger. Aureobasidium sp. a yeast-like mold that is common. particularly in temperate zones. It is found in water, soils and associated with wood and plant materials, including the aerial portions of plants. Indoors, it grows well wherever water accumulates, such as bathrooms and kitchens, on shower curtains, tile grout, window sills and other areas with high water activity. It is a common allergen and is also associated with hypersensitivity pneumonitis. No toxins have been discovered to date. it is rarely involved in keratitis and cutaneous infections, and there have been a few cases of deep infections in immunocompromised patients. Basidiomycetes - Widespread and common group of Fungi that includes the mushrooms, puffballs, shelf fungi and many other fungi. Containing over 1,200 genera, they exist as saprophytes and plant pathogens. Although they are less commonly found growing indoors, when present they are usually associated with wood, which they degrade and potentially destroy the structural integrity of the building. They grow very slowly, and are therefore usually found in areas which have remained consistently wet over long periods of time. Their growth in laboratory culture is also very slow, and they often fail to produce fruiting bodies. As a result, they are often reported as sterile mycelia. Basidiomycetes are common allergens and are also associated with hypersensitivity pneumonitis. Many mushrooms are toxic when ingested, but little is known about toxicity via the inhalation route. In rare instances, the asexual forms of basidiomycetes may cause infections in the immunocompromised patient. Beauveria sp. - cosmopolitan, it is isolated from soil, plant debris, dung and parasitized insects. It is not commonly fond growing indoors. It is reported to be allergenic. In rare instances it has been involved in keratitis and pneumonia in immunocompromised patients. Bipolaris sp. Group} - Cosmopolitan fungus, although some species are found mainly in tropical and subtrOpicaI regions. They exist in soil and as pathogens of plants. They grow indoors on a variety of substrates. They are allergenic and are very commonly involved in allergic fungal sinusitis. They are opportunistic pathogens but occasionally infect healthy individuals, causing keratitis, sinusitis and osteomyelitis, Botrytis sp. - Widespread, principally in humid environments of temperate and subtropical regions. This fungus is generally found in saprophytic and parasitic relationships with plants, and can sometimes be found indoors in association with plants. it can also be found on stored fruits and vegetabies. Reported to be allergenic and a cause of hypersensitivity pneumonitis. It is a very rare cause of keratitis. Cheetomium sp. Cosmopolitan Ascomycete fungus, commonly isolated from soil and from decomposing plant materials, especially woody or straw-like materials. It is cellulolytic and grows well indoors, particularly on damp sheetrock and other paper substrates. It is often found growing with Stachybotrys. It is reported to be allergenic. A few species produce toxins as well as secondary metabofites that are not toxins in the true sense but have toxic effects nonetheless. A variety of mutagens are also produced. sp. cosmopolitan and common saprophytic soil fungus. This genera is a heterogeneous assemblage of over 10 species, some of which are strongly cellulolytio it is more commonly found in temperate regions, although a few species occur in tropical and subtropical regions. It can be found in a variety of soils, plant litter, activated sludge, compost, wood and preservative?treated wood. Indoors it may be expected to be found on a wide variety of substrates, particularly those with a high cellulose content. There are reports of questionable reliability concerning its involvement in skin and nail infections, although one species has been substantiated, on rare occasion, as an agent of onychomycosis. Cladosporium sp. a One of the most common genera worldwide and perhaps the most commonly encountered fungus both indoors and out. It is found in soil of many different types, plant debris and on the leaf surfaces of living plants. The outdoor numbers are reduced in the winter and often relatively high in the summer, especially when humidity is high. Often found indoors in numbers less than outdoor numbers. Indoors, it can be found growing on many substrates, including textiles, wood, moist window sills and on the surface of fiberglass duct liner in the interior of supply ducts. Producing greater than 10 allergenic antigens, it is a common cause of allergy and may be associated with hypersensitivity pneumonitis. Cladosporium carrionif, although very rarely encountered, can cause mycosis. The toxic secondary metabolites cladosporin and emodin may be produced, although neither are highly toxic. Curvularia sp. - More commonly found in tropical and subtropical regions. but a few Species are commonly isolated in temperate agricultural areas. They exist in soil and plant debris, and are facultative pathogens of living plants. Reported to be allergenic as well as a relatively common cause of allergic fungal sinusitis. It is occasionally a cause of human infection, including keratitis, sinusitis, onychomycosis, mycetoma, pneumonia, endocaditis and dessiminated infection. These cases of infection have occurred principally in immunocompromised individuals. Drechslera sp. see under Bipolaris sp. Epicoccum sp. Cosmopolitan fungus found in soil, plant litter and as a secondary invader of living plant tissues. It can grow indoors on a variety of substrates, including paper and textiles. It is a common allergen and produces several antibiotics which may be potentially toxic via inhalation. No cases of infection have been reported in humans or animals. Exophiala 5p. Cosmopolitan fungus, isolated from soil. decaying wood and surfaces in contact with water. This fungus is poorly studies in terms if indoor air quality, but is likely to produce allergy as well as other common phenomena, such as hypersensitivity It is an occasional cause of mycetomas and other subcutaneous infections. Exophiala werneckr?i is the etiologic agent of a superfical infection known as tinea nigra. Fusarium sp. - Cosmopolitan, frequently isolated from soil and plant debris. Some species are plant pathogens. It is occasionaily found indoors on a variety of substrates and in humidifiers, and requires very moist conditions. It is reported to be allergenic. Several species in this genus can produce potent toxins, including trichothecenes, T-2 toxin, fumonisin, vomatoxin and others. It has a history of severe toxicoses, particularly in terms of agriculture and the ingestion of contaminated grains. It is occasionally a cause of keratitis, endophthalmitis an mycetoma. it has also been involved in disseminated infection in the immunocompromised patient. Geotrichum sp. - Cosmopolitan saprophytes, isolated from soil and plants and frequently from grains, fruits, dairy products, paper, textiles and water. Geotricnum candidum is considered part of the normal human flora. It may grow indoors on a wide range of substrates, generally where high moisture is present. Allergic reactions have been reported. Information on its pathogenicity has suffered from unreliable identifications, but it is believed to be involved in infections of oral, bronchial and bronchopulmonary epithelia as well as skin.

Some species are parasites of plants. They are occasionally found indoors, particularly on wood and wood products where it may greatly reduce structural integrity. thalophora verrucosa is one of the agents of chromoblastomycoses. Several other species cause diverse types of phaeohyphomycosis, in the forms of mycotic arthritis, subcutaneous osteomyelitis, and cerebral or desseminated infection. Phoma sp. - Cosmopolitan Ascomycete fungus frequently isolated from soil, plant materials and fruits. Indoors it is frequently found on walls, ceiling tiles and on the back-side of linoleum.

Rhizomucor sp. - Cosmopolitan, thermophilic fungus isolated from soil, decaying organic matter and compost. It occupies a biological niche similar to Mucor sp. and Rhizopus sp. This Zygomycete fungus is reported to be allergenic and is often linked to occupationai allergy. Rhizomucor pusillos is occasionally an agent of pulmonary, facial, cerebral or disseminated zygomycosis, particularly in the debilitated, leukemic patient. Rhizopus sp. - Widespread and common Zygomycete fungus that is found in soils, decaying plant material, dung, compost and varoius agricultural products such as vegetables and cereals. Indoors it may be found on a variety of substrates, although more often on food products than on environmental surfaces. It is allergenic and an agent of hypersensitivity pneumonitis, and is often linked to occupational allergy. Toxin production is not known to date. Rhizopus is the principal agent of zygomycosis. Individuals primarily affected are those suffering from diabetic ketoacidosis, malnutrition, severe burns or conditions that result in a compromised immune system.

Sporobolomyces sp. - Cosmopolitan fungus found on tree leaves, soil, plant litter and on plant lesions as a secondary invader. It is found indoors on a variety of substrates but requires very wet conditions for growth. It is reported to be allergenic. Toxin production is not known to date. It is implicated as a cause of dermatitis. Sporothrix sp. Rarely encountered fungus indoors, it is fairly widespread outdoors and is found in decaying wood, soil, vegetable debris, sphagnum moss, fertilizers and in association with bark beetles. It is found worldwide in both temperate and tropical zones, predominantly in Central South America, Mexico, eastern Europe and the north-central United States. There are more than 24 species characterized to date, but some taxonomic confusion exists with members of the genus Opbiostoma and Sporotrichum. One species of Sporothn'x, S. scnenckii, can cause sporotrichosis, which is a chronic cutaneous and subcutaneous mycosis. The infection can be contracted by inhalation. Although healthy individuals can become infected, the type and severity of infection are dictated by the portal of entry of the fungus and by the immunocornpetence of the host. Sporotrichum sp. - Reported to be allergenic. See under Sporothrix sp. This fungus is a basidiomycete anamorph displaying characteristic clamp-connections on its hyphae, and is generally easily distinguished from Sporothrix. This genera does not cause sporotrichosis. Stachybotrys sp. - Widespread and commonly found in soil and on decaying plant substrates. it is a very effective at decaying cellulose, and can be found indoors on wet materials containing cellulose, such as wallboard, ceiling tile, cardboard, and other paper-based materials. In laboratory culture, it is a relatively slow- growing fungus and does not compete well with other, faster-growing fungi. Due to the "sticky" nature of its spore arrangement, it does not become airborne easily. Irregardless of the type of medium employed, its spores have a relatively low percentage of viability in lab culture {especially once released into the air), and spore-trap samples are by-far the best for demonstrating the presence of this fungus in the air. Similarly, direct observation of bulk materials is often preferable over laboratory culture. Allergens of Stachybotrys are poorly studied, but Type I allergies have been reported. No cases of infection have been reported in humans. Some speciesistrains of this fungus (S. atra, S. chartarum and S. alternans are synonymous) produce several macrocyclic trichothecene toxins which have been shown in laboratory studies to be very potent toxins. Most reports of toxicosis in humans are circumstantial, and much research is currently being carried out in this area. Individuals with chronic exposure to Stachybotrys spores have reported cold and flu sore throats, cough, diarrhea, headache, fatigue, dermatitis, rhinitis, itching or burning sensation in mouth, throat, nasal passages and eyes, and generalized malaise. The toxins produced by this fungus can suppress the immune system affecting the tissue and the bone marrow. Animals injected with the toxin from this fungus (in doses much higher than would be experienced via inhalation of spores) exhibited the following necrosis and hemorrhage within the brain, thymus, spleen, intestine, lung, heart, node, liver, and kidney. Reports of lung hemorrhage in humans exist, but are presently controversial and unsubstantiated. The mycotoxin is also reported to be a liver and kidney carcinogen . Per-cutaneous absorption has caused mild sp. Common fungus found in soil and on wood and decaying vegetation. It grows on general laboratory media but often fails to sporulate. It is rarely found growing indoors. It is known to be allergenic and shares several allergens with Alternaria. It is not known to be toxigenic, and has only rarely been implicated as a cause of infection in humans (sinusitis). Sterile Myceiia - Mycelia are the branching cellular ?laments by which fungi grow. Colorless sterile mycelia are white or transparent mycelia in which no fruiting structures are produced (non-sporulating). Dematiaceous sterile mycelia are dark olive~green to dark brown-to-black mycelia in which no fruiting structures are produced fnon-sporulating). Many fungi from the environment do not adjust well to growth on laboratory media, and therefore do not sporulate. Others, such as the Basidiomycetes and many of the Ascomycetes produce very specialized fruiting bodies that take a long time to form. They will therefore often be classified as non-sporulating due to the limited amount of incubation time employed for IAQ samples. Unless specific sporesffruiting bodies are formed, identification of these fungi is not possible. The allergenic and toxigenic potential of sterile mycelia is dependent on the actual type of fungi that is present. In general, toxins are likely to be low, since most fungal toxins are associated with spores. All should be considered to be allergenic to some extent, and toxigenic secondary metabolites may be produced and excreted by the hyphae. Torula sp. - Widespread fungus found in soil and on wood, grasses and in the roots of several types of plants. it occurs more commonly in temperate regions. It grows well on laboratory media but usually does not sporulate. it can be found growing indoors, particularly on cellulose-containing materials. it is allergenic and has been reported to produce toxic substances in laboratory tests. Trichoderma sp. - Widespread fungus found in soil and on decaying wood, fruits, vegetables, grains, paper and textiles. It grows extremely well on general laboratory media, often overtaking and obscuring other fungi. it is often found indoors growing on wood, paper products, tapestry, unglazed ceramics and a variety of other products. it is strongly cellulolytic. it is allergenic and an agent of hypersensitivity pneumonitis. It produces a wide variety of toxic substances, including some that are closely related to the trichothecene mycotoxins of Stachybotrys. It is commonly found in soil, dead trees, pine needles, paper, and unglazed ceramics, and readily degrades cellulose. It often will grow on other fungi. It produces antibiotics which are toxic to humans. it has been reported to be allergenic Trichophyton sp. - Found in soil and on the skin of warm-blooded animals. Can cause ring worm, athlete?s foot, and infections of skin, nail, hair and scalp. Reported to be allergenic. Trichothecium sp. - Found in decomposing vegetation, soil, corn seeds and in flour. The species Trichothecium roseum can produce a trichothecene toxin which may be associated with disease in humans and other animals. Reported to be allergenic. Unknown Colorless Spore Category used in spore-trap and direct microscopic analyses to describe all non-distinctive, unidentifiable colorless spores. Unknown Dematiaceous Spore - Category used in spore-trap and direct microscopic analyses to describe all non- distinctive, unidentifiable spores that are dark olive-green to dark brown-to-black. Ulocladium sp. - Widespread fungus found in soil and on decaying plant material, dung, grasses, wood, paper and texiles. Growth indoors is very common, where it grows in materials with a high water content, including wallboard, paint, textiles and paper~based materials. It is considered a major allergen and shares many antigens with Alternaria. It is not known to be toxigenic, and has only rarely been implicated as a cause of infection in humans (subcutaneous tissue infection). Verticillium sp. Commonly found in soil and on decaying vegetation. it is a major pathogen of plants as well as insects, but is not considered pathogenic to humans {although it may be a rare cause of corneal infections and keratinitis). Very little is known about its allergenic and toxigenic potential via inhalation in humans. Wallemia sp. - Widespread fungus found in soil, textiles, hay and in many food items with a low water-activity (for example, foods with a high sugar or salt content. It is known as xerophilic or osmophilic, indicating that it prefers relatively dry conditions. It grows poorly on general laboratory media, instead requiring specialized media with a lower water- activity such as 8 or MBA with high sucrose. It can be found indoors on wood and as a component of dust, often colonizing the relatively dry components of dust such as organic debris and dander (skin cells). It is known to be allergenic and produces several toxic metabolites. It has only rarely been implicated as a cause of infection in humans. Yeast - Various types of yeast are commonly observed in air and bulk material samples. Yeast are typically found in moist environments such as wet carpeting, cooling coils, drain pans and humidifiers. Yeast, although a type of fungus, require high moisture conditions and unlike fungal spores, cannot survive extended dry conditions. They may also exist as commensals on the skin and oral cavity of building occupants, and may be shed into the air by normal activity. Some yeast are reported to be allergenic. Positive skin tests have been reported. Some types of yeast such as Candida sp. and Geotrichum sp. can cause serious infections in immune-compromised individuals.
