Abstract:
The mutagenicity of urinary extracts from workers employed in a petroleum plant was analyzed by means of the plate test using S. typhimurium strains TA98 and TA100. Mean urinary mutagenic activities in TA98 were 2-14 times higher in the petroleum plant workers than in the control group. In TA100 these differences were even bigger, the mutagenicity in petroleum plant workers' urine being 3-42 times higher than in the control group. These results suggest that the environmental exposure of people to mutagenic substances is markedly increased in a petrochemical plant.
