The excess risk for cancer due to lifetime occupational exposure, 8 hours per day, 5 days a week, 50 weeks per year for 45 years, to butadiene at the proposed OSHA standard of 2ppm was estimated by fitting the bioassay data to a multistage Weibull time to tumor model and applying various mouse to human scaling factors. (cdc.gov)
The excess cancer risk was expressed as a function of tumor site and derived from mice to humans based on body weights raised to the three fourths power. (cdc.gov)
The authors conclude that when based on the most sensitive site (the female mouse lung) the excess risk for cancer resulting from lifetime occupational exposure to 2ppm butadiene would be approximately 600 tumors/10,000. (cdc.gov)
Although varying the assumptions and considering other tumor sites can lower the estimated risks, the results suggest that prolonged exposure to 2ppm butadiene may present a significant cancer risk and that work related butadiene exposures should be reduced to the lowest feasible level. (cdc.gov)
