Chromosome analysis was undertaken on lymphocyte cultures taken from (1) six workers with estimated exposure to VC and four workers with monitored exposure to VC (employed in the BASF); (2) 20 workers showing symptoms of VC illness with unknown exposure and one angiosarcoma case, due to VC exposure (not employed in the BASF); and, (3) on bone marrow cells of Chinese hamsters after inhalation of 2,500 ppm or 5,000 ppm, or after intraperitoneal injections of 300 mg/kg or 600 mg/kg. The proband groups showing symptoms of VC illness, the only living angiosarcoma case, and the animal test show a significant increase in the rate of aberrations in comparison to the control group. |
