【摘要】 本文通过铬盐生产工人发铬含量与空气铬、尿铬、性别、工龄之间的比较,初步探讨发铬作为铬盐生产工人生物监测指标的意义。结果表明铬盐工人发铬与正常对照组之间有非常显著差异(P<0.01);发(?)与空气铬浓度呈低度正相关(r=0.285);发铬在男女接触工人之间无统计学差异,但女工偏低;发铬与尿铬、工龄无相关关系。更多还原

【Abstract】 Hair chromium contents from 61 chromium salt workers and 54 unexposed teachers and students were determined. The results showed that the hair chromium contents of the exposed group had a significant difference (P<0.01) from that of control group. However, it showed no difference in the exposed group with various exposed time(P>0.05); The hair chromium only showed a low positive correlation(r=0.285) with the chromium concentration in the workplace air. The relationshop between hair and urine chromium was not well correlated (r=-0.038). It suggested that the hair chromium probably indicated a level of past exposure and might served as a reference index for excessive exposure.更多还原
