The genetic risk run by workers occupationally exposed to chemicals, including the newly developed cytostatics, was assessed in large chemical laboratories. The exposed group comprising 38 people consisted of chemists, laboratory assistants and pilot plant workers. The average rate of aberrant cells in peripheral blood lymphocytes (AB.C). was 3.9% and the value of break/cell ratio was 0.046. The group of matched controls (N = 18) was found to have 1.5% of AB. C. and 0.020 breaks/cell. In the exposed group, there were, on average, 8.94 SCEs/cell, and in controls, 5.81. Urine mutagenicity tests on Salmonella typhimurium tester strain TA98 revealed a significant increase of activity in 23 (64%) out of 36 urine samples tested as compared to the control group (N = 19) with 4 (21%) positive urine samples. Strain TA100 showed only a weak response to urine mutagens.
