Description:Investigators from the National Institute for Occupational Safety and Health (NIOSH) recently re-evaluated residual arsenic contamination in an abandoned building in Norwood, Ohio. At the request of the local health department, NIOSH had evaluated the same building in 1974 and found it highly contaminated by an arsenic trioxide rodenticide that had been mixed and packaged in the building nearly 40 years earlier. On October 22, 1981, NIOSH investigators collected 14 dust samples from the floor, walls, and ceiling beams throughout the building and analyzed them for arsenic content by atomic absorption spectrophotometry. Six samples from the floor contained from 3% to 41% arsenic by weight (30,000 to 410,000 parts per million). Five wipe samples from wall surfaces contained from < 0.5 to 310 microg of arsenic per square inch of surface area, and three wipe samples from ceiling-beam surfaces contained from 130 to 2100 microg of arsenic per square inch. (Normal levels are < 0.5 microg.) The highest arsenic concentrations were found in the northeast quadrant of the building - the area where the mixing and packaging had reportedly been done. On February 2, 1982, NIOSH presented the results to the Norwood City Health Department with recommendations for decontamination and guidelines for protection of workers during decontamination.
