摘要
通过铅锌冶炼厂废气对周围环境和青少年健康影响的调查,发现该厂周围环境已明显污染。污染区的青少年血铅浓度和氟斑牙患病率均有明显增高,而红细胞计数和唾液溶菌酶活性均有显著性降低,并有早期肺功能受损的表现。提高铅锌厂烟囱的高度后并未使大气污染物浓度降低到大气质量三级标准。
Through the investigation of a lead-zinc smelter semission on peripheral environment and the effects on the youngsters' health, it was found that emission of the smelter polluted the peripheral environment obviousely and increased the blood lead concentration in body and morbidity rate of dental fluorosiso Not only the RBC counting and salivary lysozyme activity were decreased but also early damage of the youngsters' lung function,which was found(FEF_(75-85)in the pollution area. To increase smelter's chimney height could not efficiently decrease the level of air pollution.
