title: Chromosomal effects of cadmium exposure in humans.
abstract: Cytogenetic studies on subjects occupationally or environmentally exposed to cadmium are reviewed and discussed. After a first report of increased chromosome aberrations in lymphocytes of itai-itai patients from Japan, several studies on workers occupationally exposed to cadmium gave conflicting results. These differences may perhaps be explained by the action of co-factors (e.g., nutritional deficiencies in itai-itai patients; concomitant exposure to other metals in some occupational groups), or by different levels of exposure. In a study on cadmium workers with a wide range of cumulative exposure, as compared with matched controls, an increase in chromosome-type aberrations in lymphocytes, an indicator of cumulative damage, was found only because of the increased rates in the subgroup with the highest cumulative exposure and cadmium burden. As far as environmental exposure is concerned, of two recent reports, one from China is positive for chromosome aberrations and the other, from Japan, is negative for sister chromatid exchanges.
