Metals: beryllium, A total of 45 air samples were collected for 27 different metals including arsenic, phosphorus, cadmium, chromium, cobalt, lead, magnesium, manganese, molybdenum, nickel, selenium, silver, tellurium, thallium, vanadium, and zinc. Only trace amounts of these metals were detected on any of the air samples.
Polynuclear Aromatic Hydrocarbons:
A total of 12 air samples were collected for 16 different polynuclear aromatic hydrocarbons (PAHs) including anthracene, benzo(a)anthracene, benzo(b)fluoranthene, benzo(a)pyrene, chrysene, phenanthrene, and pyrene. Only trace amounts of PAHs were detected on any the air samples. Four of the PAHs detected on the air samples in trace amounts are the suspected human carcinogens benzo(a)anthracene, benzo(b)fluoranthene, benzo(a)pyrene, and chrysene.
Respirable Particulate: A total of 18 air samples were collected for respirable particulate and indicated TWA concentrations ranging from none detected to 0.32 mg/m3. These measurements are well below the OSHA PEL of 5 mg/m3. (NIOSH does not currently have an REL for respirable particulate.)
Respirable Crystalline Silica:
A total of 18 air samples were collected for respirable crystalline silica. No respirable crystalline silica was detected on any of these air samples.
Total Particulate: A total of 36 air samples were collected for total particulate and indicated TWA concentrations ranging from none detected to 2.3 mg/m3. These measurements are well below the OSHA PEL for total particulate of 15 mg/m3. (NIOSH does not currently have an REL for total particulate.)
Volatile Organic Hydrocarbons:
A total of 76 air samples were collected for volatile organic hydrocarbons including benzene, ethyl benzene, styrene, toluene, and xylene(s). Except for benzene, only trace amounts of VOCs were detected on any of these air samples. Two of these samples (0.35 and 0.46 mg/m3) 3
