Interim results of a mortality and industrial hygiene survey of workers exposed to styrene (100425) were described. The cohort consisted of 5368 workers employed at two fiberglass reinforced plastic boat manufacturing facilities in Washington State. The vital status of the cohort was determined as of December 31, 1977. Death certificates were examined and coded. The relative risks of mortality from lung, lymphatic and hematopoietic, male genital, and other cancers and mortality from all causes were calculated for the white male subjects using the white male population of the United States as the reference. Industrial hygiene sampling for styrene was performed at the two studied facilities and five other plastic boat manufacturing facilities. The mean styrene concentrations in the two surveyed facilities were 42.5 and 71.7 parts per million (ppm). The mean styrene concentrations at the other facilities ranged from 35.9 to 90.0ppm. The permissible time weighted average exposure level for styrene was 100ppm. Only 3 percent of the cohort members had died as of December 31, 1977. The only significant finding thus far was an excess of mortality from male genital cancer, four deaths versus 1.7 expected. The transcript of a discussion session following the presentation was provided.
