电子废物含有大量的金属、塑料和阻燃剂等物质,如果处理不当,电子废物将向环境排放种类繁多的有毒有害物质,从而产生严重的环境污染问题。近年来,国内外学者对电子废物处理所致的生态环境问题给予了相当的关注,已经开展了不少相关研究,这些研究主要集中在我国的几个电子废物处理处置典型地区。本文对近5年来的相关研究成果进行了系统综述,内容涉及电子废物处理处置过程中产生的主要环境污染物,电子废物处理处置活动所致的土壤、水体和大气的重金属和持久性有机污染物污染以及电子废物处理处置活动对动植物和人体的污染风险等,并提出将来关于电子废物研究中需要关注的问题。
Electronic wastes contain a lot of toxic metals, plastics and fire retardants, inadequate E-waste recycling activities may bring serious environmental pollutions. Scholars in recent years have paid great attention to the environmental problems caused by e-waste disposal The studies were mainly in the several important E-waste recycling areas in China. In this paper, surveys and researches on environmental pollutions caused by e-waste recycling activities published in recent 5 years are reviewed. The researches related to the main released pollutants, as well as the negative impacts on soil, water, air, living organisms and exposures to human bodies caused by heavy metals and POPs from e-waste recycling activities.
