Community exposure and medical screening near chromium waste sites in New Jersey.
Chromium waste slag containing potentially hazardous levels of hexavalent chromium was used as fill material at more than 160 residential, industrial, and recreational sites. Persons living or working in the vicinity of the sites may have been exposed through inhalation, ingestion, or skin contact with contaminated soils and dusts. In 1992-1993, the New Jersey Department of Health and Senior Services (NJDHSS) and the Environmental and Occupational Health Sciences Institute (EOHSI) conducted a screening project to assess exposure to chromium and to provide medical evaluations to people living in 14 residential areas or working in 78 workplaces near chromium waste sites. The screening included a physical examination for irritant or allergic effects and a urine chromium test for recent exposure. Participants were referred for follow-up medical evaluation if specific criteria were met. Of 800 residents and 938 workers receiving the screening physical examination, 32 adults were referred for follow-up evaluation. Of 806 residents and 934 workers submitting a urine specimen for chromium analysis, 158 adults and children had levels exceeding specified criteria and were referred for follow-up evaluation. The proportion of persons referred on the basis of the urine chromium test varied among screened groups. Multiple linear regression models showed that average urine chromium differences between residents and a comparison group, adjusting for potential confounders, were highest in children under 6 years of age. Most of the persons undergoing the follow-up medical examinations revealed no apparent clinical effects attributable to chromium exposure. The screening results indicated the need for expanded environmental evaluation in specific residential areas and workplaces.
