【摘要】 目的:探讨电子垃圾拆解区(贵屿镇)儿童铅污染现状及其对儿童健康的影响。方法:选择贵屿镇154名(1~8)岁儿童(暴露组)及邻镇陈店镇124名同年龄段儿童(对照组)为研究对象;采用石墨炉原子吸收光谱法测定血铅水平(BLL)。结果:与对照组比,暴露组BLL几何均值为121.3μg/L,其中69.5%的儿童血铅值大于100μg/L(P<0.01)。结论:电子垃圾拆解区大多数儿童处于高铅负荷状态,铅污染对当地儿童的健康构成威胁。更多还原

【Abstract】 Objective:To investigate the children’s lead burden level in an electronic waste recycling area(Guiyu)and to discuss the effects of electronic waste on children’s health.Methods: One hundred and fifty-four children aged from 1 to 8(exposure group)lived in electronic waste recycling area and 124 of the similar aged children(control group)lived in its adjacent area(Chendian)were chosen,and the blood lead level(BLL)was determined by graphite atomizer absorption spectrophotometer.Results: Compared with the control group,the geometric mean of BLL in the exposure group was 121.3 μg/L,and 69.5% of them had exceeded 100 μg/L(P<0.01).Conclusion: Most children from the electronic waste recycling area have high lead burden level, and environmental lead pollution has been threatting the children health around the recycling site.更多还原
