CYTOGENETIC EFFECTS OF ELECTROPLATING WORKERS
电镀工人的细胞遗传学效应

A group of 34 electroplating workers occupationally exposed to nickel or chromium and a control group of 10 were examined for sister-chromatid exchanges in their peripheral lymphocytes. Frequency of SCEs was significantly higher in cells of electroplating worker in comparision with controls. The level of significance was P<0.01, according to the t-test. Differences of the frequencies of SCEs between the age groups were not obvious.Out of the 34 electroplating workers, 7 workers occupationally exposed to nickel and T to chromium, not only the frequency of SCEs was examined, but also chromosomal aberrations. The results showed that the chromosomal aberrations of the workers occupationally exposed to nickel and to chromium were higher than the controls.Also, nickel and chromium "concentrations in "air of the electroplating workshop, as well as contents of nickel and chromium in hair and feces of the workers were determined,
