某冶炼厂新投产的锡冶炼系统铅砷危害状况调查结果:生产环境中铅浓度极低,有一定量的砷存在,平均浓度在0.036—0.229mg/m~3之间。接触组尿砷值显著高于对照组P<0.01,且与环境中砷浓度呈直线相关,P<0.05,提示锡冶炼系统存在砷污染及危害,应定期对工人进行健康监护。
Lead smelting system newly put into operation in a smelter Lead arsenic Hazard status Findings: The lead concentration in the production environment is extremely low, with a certain amount of arsenic present, with an average concentration of 0.036-0.229 mg / m 3. The urinary arsenic levels in the exposed group were significantly higher than those in the control group (P <0.01), and were linearly correlated with the arsenic concentration in the environment (P <0.05), indicating the presence of arsenic pollution and hazard in the tin smelting system. Workers should be regularly monitored for their health.
