无序电子垃圾拆解对人群健康的影响

Impact of informal e-waste recycling on human health

日益增多的电子垃圾已成为困扰全球环境和人群健康的重大问题。无序电子垃圾拆解回收过程中,铅、溴化阻燃剂等重金属和有机物进入空气、土壤、灰尘、水等环境介质中,造成的环境污染威胁着当地居民的身体健康。本文以广东省某电子垃圾拆解区为例,综述了我国重点电子垃圾拆解区人体重金属和有机物暴露水平及所造成的人群健康效应的研究进展。该地区电子垃圾拆解活动已造成重金属和有机物污染,当地人群体内处于重金属和有机物高负荷状态,对人体生理功能造成了一定的影响,集中拆解区的建立可以有效降低多种污染物负荷水平。

Increasing e-waste has become a major problem for global environment and public health.In the process of dismantling and recycling of disordered electronic waste,heavy metals such as lead and brominated flame retardants and organic substances are released into environmental media such as air,soil,dust and water,which is harmful to the health of local residents.Taking an e-waste dismantling area in Guangdong Province as an example,this paper reviews exposure levels of heavy metals and organic matters in e-waste recycling areas in China,as well as the health effects of local residents.Previous studies have found that e-waste recycling activities led to serious environmental pollution and high exposure levels of heavy metals and organic matters in local residents,which has a certain impact on the physiological functions of various human systems.The establishment of a centralized dismantling zone can effectively reduce the load level of various pollutants.
