Genetic damage induced by an occupational complex and prolonged chemical exposure.

Some results of a study on the clastogenicity of chemicals in vivo are reported. The chromosomes in lymphocytes from whole blood cultures were studied in 60 subjects permanently exposed for about 6 years to several occupational chemicals acting concomitantly, and in 5 controls. The exposed subjects showed an increase in the rate of chromosomal aberrations as compared to controls.
