铅在工业上广泛应用,其对人体健康的危害早为人们所熟悉。如印刷行业在熔铅、铸字、铸版等过程中产生大量的铅蒸气,浓度大大超过国家卫生标准,并严重污染周围人群的生活环境。我们曾测得广州日报印刷厂生产环境的铅蒸气浓度超过卫生标准4.81倍,厂外周围环境超过8.52～30.91 Lead is widely used in industry, its harm to human health as early as people are familiar. Such as the printing industry in the lead-melting, casting, casting process such as a large number of lead vapor, the concentration much higher than the national health standards, and seriously pollute the living environment around the crowd. We have measured that the concentration of lead vapor in the production environment of the Guangzhou Daily Printing Factory exceeds the hygiene standard by 4.81 times and the ambient environment outside the factory exceeds 8.52 ~ 30.91
