Abstract

E-waste generation has become a serious environmental challenge worldwide. Taizhou of Zhejiang Province, situated on the southeast coastline of China, has been one of the major e-waste dismantling areas in China for the last 40 years. In this review, we focused on the polychlorinated biphenyl (PCB) trends in environmental compartments, burden and impact to humans, food safety, and health risk assessment from Taizhou, China. The review suggested that PCBs showed dynamic trends in air, soil, water, biodiversity, and sediments. Soils and fish samples indicated higher levels of PCBs than sediments, air, water, and food items. PCB levels decreased in soils with the passage of time. Agriculture soils near the e-waste recycling sites showed more levels of total PCBs than industrial soils and urban soils. Dioxin-like PCB levels were higher in humans near Taizhou, suggesting that e-waste pollution could influence humans. Compared with large-scale plants, simple household workshops contributed more pollution of PCBs to the environment. Pollution index, hazard quotient, and daily intake were higher for PCBs, suggesting Taizhou should be given priority to manage the e-waste pollution. The elevated body burden may have health implications for the next generation. The areas with stricter control measures, strengthened laws and regulations, and more environmentally friendly techniques indicated reduced levels of PCBs. For environment protection and health safety, proper e-waste dismantling techniques, environmentally sound management, awareness, and regular monitoring are very important.

摘要

电子垃圾的产生已成为全球范围内的严重环境挑战。浙江省台州市位于中国东南沿海,在过去的 40 年里,它一直是中国主要的电子垃圾拆解区之一。在这篇综述中,我们重点关注了中国台州环境介质、人体负荷和影响、食品安全以及健康风险评估中多氯联苯(PCBs)的趋势。综述表明,PCBs 在空气、土壤、水、生物多样性和沉积物中呈现动态趋势。土壤和鱼类样本中的 PCBs 水平高于沉积物、空气、水和食物。随着时间的推移,土壤中的 PCBs 水平下降。电子废物回收场所附近的农业土壤中的总 PCBs 水平高于工业土壤和城市土壤。台州附近人类中二噁英类 PCB 水平较高,表明电子废物污染可能会影响人类。与大规模工厂相比,简单的家庭作坊对环境中 PCBs 的污染贡献更大。PCBs 的污染指数、危害商和日摄入量较高,表明台州应优先管理电子废物污染。升高的体内负荷可能对下一代健康产生影响。那些采取了更严格的控制措施、强化了法律法规以及更环保技术的地区,PCBs 水平则有所降低。为了环境保护和人类健康安全,采用适当的电子废物拆解技术、环境友好的管理方式、提高意识和定期监测非常重要。
