不同瓷尘作业工人的铅危害调查

Study of lead hazard due to different porcelain dusts.

本文测定了瓷尘作业环境及72名工人血、尿的铅量,并用症状评分法评价其对工人的危害。结果表明,上釉组的血铅、尿铅、尿δ-ALA均高于对照组,与作业环境中的铅含量相对应,其血铅、尿铅水平随工龄的增加有上升的趋势。瓷尘中铅对作业工人的危害可出现神经、肌肉、关节、消化等多个系统的主观症状。

The blood and urine lead level were determined from 72 workers exposed to different porcelain dust. Symptom scoring method was used to evaluate the severity of the hazard to workers. The results showed that the blood and urine lead level and urine δ-ALA level among workers exposed to lead containing porcelain dust were higher than that of the workers without lead exposure. In addition, those values were closely correlated with the dust lead level(P<0.01). It also tended to increase with the working years. In terms of subjective symptoms, multi-system symptoms like nervous, museulo-skeletal, digestive etc. were shown.
