Study of Concentration of Urinary Cadmium and Serum Sex Hormone in Cadmium-exposed Male Workers / 环境与健康杂志

ABSTRACT

Objective To evaluate the concentration of urinary cadmium and serum sex hormone in cadmium-exposed male workers and explore the affecting factors and related mechanism.Methods The individuals exposed to cadmium from three workshops 40 in each, in a cadmium rechargeable battery manufacture plant were selected as the exposure groups according to concentrations of cadmium oxide in the workplace in November 2008, namely assembly, charging and butt-weld workshop for low, moderate and high dosage group.Another forty male workers without cadmium exposure of the same plant were selected as the control group.Urinary cadmium, serum testosterone,FSH and LH concentrations were measured and urinary cadmium concentration abnormity rate was calculated for the following analysis.Results Compared with the control group, the urinary cadmium concentration and its abnormity rate of the low and high dosage groups were all significantly increased(P9 years groups were all significantly increased(P
