Impact of Lead Pollution in Environment on Children''s Health in Shenyang City
沈阳市环境铅污染对儿童健康的影响

In this thesis, based on field sampling and indoor integrated analysis with GIS technology, the impact of lead pollution in the atmosphere, dust, soil on the children was explored systemically. Results showed that, Lead exposure in environment was widely distributed and Lead pollution was serious in Shenyang city. The spatial variations of Lead, with four high content centers in the soil, dust and atmosphere, were distinct in all the environmental media. Moreover, there were daily, seasonal and annual variations in the atmosphere. The impact of lead pollution in environment on children health was serious in Shenyang city. The blood lead content of the children (ZPP > 2.3 mumol/L) with the age of 0-10 ranged from 10.98 to 511.2 micrograms/L, and the average of 135.59 micrograms/L. The blood content of 40% children was beyond the normal standard. And correlative degree of lead contents between in blood and in atmosphere was highest, secondly in soil, and last in dust. With the implication of non-lead gasoline the lead content in the atmosphere had declined greatly. Along with the flying dust, the lead in the soil and dust was likely to entering into the atmosphere to bring out potential pollution risk.
