目的评价电子垃圾回收产业对广东贵屿环境质量的影响。方法对贵州省两个电子废物回收场地和一个农业区的地表水、地下水和沉积物样品进行分析，根据中国制定的环境质量标准，评价电子废物回收对贵屿环境质量的影响。结果3个地点地表水中铅、铁含量差异有统计学意义。第一站铅的最大值超过地表水环境质量标准门槛8倍。污染样品中铁的浓度是背景样品的22倍。三个地点的地下水样本中的锰和铁也有显著差异。铁含量是地下水水质标准下限的22倍，是背景样品的120倍。此外，8种重金属的测定结果在不同沉积物样品之间均有显著差异。污染样品中铜、镉、镍和铅的浓度高于美国国家海洋和大气管理局(NOAA)的中值基准。铜含量为2670 mg/kg，是基准中值的10倍。结论电子垃圾回收利用对贵屿造成了严重的污染。
OBJECTIVE To evaluate the environmental quality of Guiyu, Guangdong impacted by the electronic waste recycling industry. METHODS The surface water, ground water and sediment samples taken separately from two sites that recycle E-wastes and other rubbish relevant to the E-waste recycling, and an agricultural area, were analyzed, and the data were used to evaluate the impact of E-waste recycling on the environmental quality of Guiyu based on environmental quality standards in China. RESULTS The concentrations of lead and iron in the surface water samples significantly different in the three locations. The maximum value of lead in the first site was 8 times higher than the threshold of environmental quality standards for surface water. The concentration of iron in polluted sample was 22 times that of the background sample. Manganese and iron also showed a significant difference in ground water samples between the three sites. The amount of iron was 22 times that of the threshold of the quality standard for ground water, and 120 times that of the background sample. Moreover, the results of all the eight heavy metals showed significant differences among the sediment samples. The concentrations of copper, cadmium, nickel, and lead in the polluted samples were above the median benchmarks of National Oceanic and Atmospheric Administration (NOAA). The copper concentration of 2670 mg/kg was 10 times that of the median benchmark. CONCLUSION E-waste recycling has led to the severe pollution Guiyu.
