对某蓄电池企业铅中毒发病状况及趋势进行预测分析。结果显示:某蓄电池厂自建厂以来共发生377人次的铅中毒,铅中毒的患病率为2.99%,经过持续不断的落实和完善预防控制措施,铅中毒得到了有效控制,1992年以来未再发生铅中毒;在工作场所中铅的浓度为0.31 mg/m3(铅烟的浓度为0.12 mg/m3,铅尘的浓度为0.37 mg/m3)时,则可实现铅中毒的患病率为0;在巩固现有的预防控制水平下,有望继续保持消除铅中毒的控制目标。
Predict and analyze the incidence and trend of lead poisoning in a storage battery enterprise. The results showed that a total of 377 lead poisoning accidents occurred in a battery factory since its establishment. The prevalence of lead poisoning was 2.99%. After continuous implementation and improvement of prevention and control measures, lead poisoning has been effectively controlled. Since 1992, Lead poisoning occurs again; the prevalence of lead poisoning at lead concentrations of 0.31 mg / m3 at workplace (0.12 mg / m3 for lead and 0.37 mg / m3 for lead dust) is 0; under the current level of prevention and control, it is expected to continue to control the goal of eliminating lead poisoning.
