Abstract
Environmental sampling was conducted to determine time weighted average exposure concentrations for carbon-monoxide (630080), lead (7439921), sulfuric-acid (7664939), total particulate, benzene (71432) and noise and employees were given pre- and post-shift carboxyhemoglobin (COHb) tests at Peace Bridge, Buffalo, New York and at Rainbow Bridge, Niagara, New York. The evaluation was requested by the U.S. Department of Justice on behalf of an unspecified number of inspectors employed by the Immigration and Naturalization Service (SIC-9221) and the Bureau of Customs to determine if employee exposures to auto emissions during routine inspection tasks posed a health problem. Ecolyzer monitoring devices with recorders were placed in inspection booths and concentrations of carbon-dioxide, lead, total particulate, sulfuric- acid and benzene were sampled. Lead samples were collected on filters and analyzed by atomic absorption. Benzene samples were collected on charcoal tubes and analyzed by gas chromotography and sulfuric acid samples were taken in filters and analyzed by ion chromatography. Total particulate was determined by gravimetry. Dosimeters were used to measure noise and an Ecolyzer Carboximeter was used to determine carboxyhemoglobin levels. Sample analysis indicated no detectable concentrations of sulfuric-acid and low concentrations of benzene at 0.08 milligrams per cubic meter (mg/m3), total particulates at 0.76mg/m3, and lead at 0.008mg/m3. Noise measurements were 15 percent of the recommended levels. The authors conclude that no health hazards exists at the two bridge crossings and they recommend the continuation of the practice of rotating inspectors.
