为了解铬对接触工人子代智力的影响，采用美国丹佛智力筛查法（ＤＤＳＴ），对接铬工人的５８名子女与４８名对照儿童进行了智力发育检查。结果表明，接触组作业环境空气中铬浓度为００１２～００４６ｍｇ／ｍ３。接触组儿童的动作能、应物能、言语能和应人能４个项目的智力发育水平均显著低于对照组（Ｐ＜００５或Ｐ＜００１），其中以应物能（细动作能）最敏感。提示铬作业对子代智力发育可能存有不良影响。 In order to understand the impact of chromium on the intelligence of offspring workers, IQST was used to examine the intelligence development of 58 children with chromium workers and 48 control children using DDST. The results showed that the concentration of chromium in air of working environment of contact group was 0012 ~ 0046 mg / m 3. The level of mental development of children in contact group was significantly lower than that in control group (P <005 or P <001) Fine action can) the most sensitive. Tip chromium job on the mental development of offspring may have adverse effects.
