Other sources that can cause elevated particle counts include carpeting, water-damaged building materials, mold, improper exhausting of contaminants (such as in bathrooms and cooking sources), hygiene products, aerosols, and outdoor air infiltration. Porous contents can be difficult to fully clean and may harbor elevated amounts of dust and microbial spores. o Elevated 0.3 and 0.5-micron sizes are considered ultrafine particles that usually consist of fragments of organic particles such as bacteria, fungi, viruses, and insects, and often indicate outdoor air infiltration (such as common outdoor allergens), or combustion sources such as cooking or smoking. o 1.0 and 2.5-micron sizes may include spores from pathogenic Aspergillus & Penicillium. • Measurements for total volatile organic compounds (TVOCs), carbon monoxide, relative humidity (RH), carbon dioxide and temperature mostly registered within the healthy indoor air threshold. • Refer to the IAQ data chart for more information. Lab Result: Air samples for laboratory analysis were collected in Room 7 as well as an adjacent room to help determine airborne microbial levels. • A slightly elevated (960 counts/m3) level of the pathogenic fungi Aspergillus/Penicillium-like was identified in the room adjacent to Room 7. These fungal spores were likely dispersed from Room 7, since no other known fungal issues were observed outside of Room 7. However, additional historical data or inspection may be needed to ensure that other issues are not present outside of Room 7 that could have been the cause of these fungal spores within the air. o The normal indoor condition for this type of fungi ranges between 0-650 spores. Lower levels of pathogenic fungi are occasionally identified indoors. Elevated levels of these pathogenic types of fungi may cause stronger allergic symptoms and can create sick-like reactions in most people. Younger and older individuals, and those who have sensitivities or are immunocompromised, are especially vulnerable. Sensitive individuals may experience allergic-like reactions at lower levels. o Pathogen is defined as a substance capable of causing infection or disease in otherwise healthy people. Pathogenic molds cause illness by growing in or on human tissues and most often require professional remediation. o Aspergillus and Penicillium are two of the most commonly found pathogenic fungi in problem buildings. Because the spores of Aspergillus and Penicillium are very similar, they are not differentiated by microscopic analysis and are reported together. These fungal types are capable of producing potent mycotoxins and are considered an indication of a current or prior moisture issue in a building. • A low (120 counts/m3) level of the pathogenic fungi Aspergillus/Penicillium-like was identified in Room 7. o See the fungal description above. • Low (below 500 counts/m3) levels of the allergenic Ascospores, Basidiospores, Cladosporium, Curvularia and Myxomycete/Rust/Smut-like were identified. o Allergenic fungi appear outdoors at moderate and high levels and are often identified indoors at trace and low levels. Many people exposed to higher levels of these types of DocuSign Envelope ID: 8114697F-F41C-43F1-AFE2-ADC7016F0955
