摘要
对上海市郊两个县的１０家蓄电池厂和１家铅冶炼厂调查发现，５１个作业点的２３９个空气铅样品的几何平均浓度为０．０４２ｍｇ／ｍ３，作业点和样品的超标率分别为５０．９８％和５４．３９％；１９６名铅作业工人的几何平均血铅、ＺＰＰ水平分别为１．６８μｍｏｌ／Ｌ和２．６７μｍｏｌ／Ｌ，均显著高于对照厂工人。研究还发现，在血铅水平为１．６８μｍｏｌ／Ｌ时，铅接触工人的神经、消化、肌肉关节系统的症状改变，与对照工人比较差异具有显著意义。多元逐步回归分析发现，影响铅接触工人血铅水平的主要因素是卫生习惯。
en battery manufactures and one
secondary lead smeltery were intensively surveyed in two counties of Shanghai
municipality.The results of environmental monitoring of workplaces showed that the geometric
mean of air lead level was 0.042 mg/m3(0.001to 0.543 mg/m3)with the exceeding rates,the
percentage of air lead level being above the current MAC,of 50.98% from 51 work-sites and
54.39%from a total number of 239 samples.The geometric mean blood lead and ZPP levels in
196 Pb-exposed workerswere 1.68 μmol/L and 2.67μmol/L respectively,which were
remarkably higher than those of controls.Compared with non-ex-posed workers,the
prevalences of the symptoms of nervous,gastrointestinal and musculoarticular systems of
Pb-exposed workerswith a geometric mean PbB level of 1.68 μmol/L were found to be
significantly higher.The multiple regression analysis showedthat personal hygienic practice
was supposed to be the principal factor affecting the blood lead level.
