本文对接触CS_2的已婚工人的自然流产和子代先天缺陷发生率进行了回顾性调查,结果表明:接触CS_2的浓度为12.1～43.0毫克/米~3的女工组和男工妻子组的自然流产和子代先天缺陷的发生率均显著高于对照组;接触5.6～7.3毫克/米~3的女工组的子代先天缺陷发生率仍显著高于对照组。根据这一结果,我们认为现行CS_2的卫生标准(10毫克/米~3)必须加以修订,CS_2的容许浓度应降至5毫克/米~3以下。
This study retrospectively examined the incidence of spontaneous abortion and birth defects among married workers who were exposed to CS_2. The results showed that spontaneous abortion and child labor in the women workers ’and boys’ wives who were exposed to CS_2 at concentrations of 12.1-43.0 mg / m 3 The incidence of congenital birth defects were significantly higher than the control group; contact with 5.6 ~ 7.3 mg / m ~ 3 female workers group the incidence of birth defects was still significantly higher than the control group. Based on this result, we consider that the current CS 2 health standard (10 mg / m 3) must be revised and the allowable concentration of CS 2 should be reduced to less than 5 mg / m 3.
