对加铬砷酸铜木材防腐工人,以其尿中砷、铬、铜含量评价职业与接触关系。调查89名木材防腐工人和232名不接触砷的对照组。采尿分析的结果:尿铬为41μg/l,铜为191μg/l,而对照组铬为63μg/l,铜为221μg/l,经过校正后统计分析,接触组尿砷78～122μg/l,高于对照组(72μg/l),有显著差异。虽然木材防腐工人尿砷高于对照组, Chromium arsenate copper wood preservative workers, with its urinary arsenic, chromium, copper content evaluation of occupation and exposure. 89 wood preservative workers and 232 non-contact arsenic control groups were surveyed. Urinary Chromium was 41 μg / l for copper and 191 μg / l for copper compared with 63 μg / l for chromium and 221 μg / l for copper. After calibration, the urinary arsenic exposure was 78-122 μg / l, Higher than the control group (72μg / l), there are significant differences. Although wood preservative urine arsenic higher than the control group,
