Technical Assistance Report No. TA-80-71, Passaic City Hall, Passaic, New Jersey.
An environmental evaluation of Passaic City Hall, Passaic, New Jersey, was conducted on June 5, 1980, at the request of the New Jersey Department of Health. The request was prompted by outbreaks of eye and skin itching, with occasional rashes, among City Hall employees. Environmental samples were taken for mineral wool, total particulates, carbon-monoxide (630080), ozone (10028156), formaldehyde (50000), nitrogen-dioxide (10102440), organics, and hydroquinone (123319). Only three of the five high volume samples collected in the return air plenum and a mixing box area contained mineral wool, and the concentrations were extremely low, ranging from 940 to 1500 fibers per cubic meter. Settled dust samples contained less than 1 percent mineral wool. The two samples collected for total particulates showed concentrations of nondetectable and 0.12 milligrams per cubic meter, respectively. The carbon-monoxide concentration in the building was about 1 part per million. There were no detectable concentrations of ozone, formaldehyde, hydroquinone, organics, nitrogen-dioxide, oxides of nitrogen, or sulfur-dioxide. The author concludes that no cause for the itching and rash outbreak could be found, and that no additional environmental sampling is warranted unless the medical evaluation indicates an unsuspected or untested environmental contaminant.
