汞是蓄积性毒物,当今工业毒理的发展,对其危害已广泛引起人们的关注。本调查目的了解氯碱车间汞污染的状况及其对职工健康影响的程度,进一步为预防汞害提供科学依据。 劳动条件与调查方法 氯碱车间是1971年投产新建车间,位于黄河上游峡谷盆地。全车间分为电解、盐水和固碱三个工段;并设有修槽、维修与分析辅助工段。氯碱生产采用汞电解法。工艺流程图(见文末)。 氯碱车间由于生产方法陈旧,设备简陋,卫生设施欠佳,生产中汞蒸气、含汞污水及盐泥中大量汞溢散车间并污染水源及周围环境。
Mercury is an accumulative poison. The development of toxicology in industry today has aroused people’s attention. The purpose of this survey is to understand the status of mercury pollution in chlor-alkali plant and the extent of its impact on the health of workers, and to provide a scientific basis for further prevention of mercury damage. Working conditions and methods of investigation Chlor-alkali workshop was put into operation in 1971 new workshop, located in the upper reaches of the Yellow River basin. The whole workshop is divided into electrolysis, salt water and solid alkali three sections; and repair tank, maintenance and analysis of auxiliary section. Chlor-alkali production using mercury electrolysis. Process flow chart (see text at the end). Chlor-alkali plant due to obsolete production methods, poor equipment, poor health facilities, production of mercury vapor, mercury-containing sewage and large amount of mercury in the salt mud spill shop and pollute the water and the surrounding environment.
