我市1985年对乡镇企业铅作业进行普查,共调查了18个工厂,接铅工人324人,实际受检305人(男138人,女167人),受检率94.1%。铅作业主要为铅冶炼(占受检数46.6%)及蓄电池(15.4%),次为机械、印刷、交通运输等。劳动卫生调查选择有代表性的作业点32个,取样44个进行测定,结果铅烟浓度最高点超标14倍,铅尘最高超标5.4倍。五岭冶炼厂6个铅烟样品有5个超标6～14倍,北湖蓄电池厂3个铅烟及3个铅尘样品全部超标3～8倍。据往年测定,也经常超标10倍以上,最高达103倍。
In 1985, the city conducted a survey on lead operations of township and village enterprises. A total of 18 factories were surveyed, of which 324 were lead workers, and 305 were actually tested (138 males and 167 females). The examination rate was 94.1%. Lead smelting operations mainly lead (accounting for 46.6% of the number of seizures) and batteries (15.4%), followed by machinery, printing, transportation and so on. Labor hygiene survey selected 32 representative work points and 44 samples were taken for determination. The result showed that the highest point of lead concentration exceeded the standard by 14 times and the highest lead exceeded 5.4 times. There were 5 samples of 6 lead smoke samples in Wuling Smelter that exceeded 6 ~ 14 times of the samples, 3 samples of lead smoke and 3 samples of lead dust in Beihu Battery Factory exceeded 3 ~ 8 times. As measured in previous years, often more than 10 times the standard, up to 103 times.
