摘要:
使用高分辨气相色谱质谱仪,采用同位素稀释技术对电子垃圾拆解场及其周边土壤和沉积物两种环境介质进行采样检测分析.检测结果表明:电子垃圾拆解场对周边环境有明显的多氯萘(PCNs)污染影响,周边土壤介质PCNs检出质量比为95.9~702 ng·kg-1,沉积物介质PCNs检出质量比为56.2~75.0 ng·kg-1;检出的PCNs同族物中,污染贡献较大的主要是MO-CNs和Di-CNs等低氯代PCNs,为58.5%,其次是Hexa-CNs,为10.5%;电子垃圾拆解场对周边环境PCNs污染主要贡献源是电子垃圾焚烧过程,污染传播的主要渠道为大气PCNs沉降作用.研究结果表明:电子垃圾拆解场对周边环境有着明显的PCNs污染影响,尤其是低氯代PCNs污染,而控制其污染的关键点是电子垃圾焚烧处置过程污染控制.
Abstract:
The soil and sediment samples collected from the e-waste dismantling were analyzed by the isotope dilution HRGC-HRMS. The results showed that there was obvious polychlorinated naphthalenes(PCNs)pollution of e-waste dismantling field on the surrounding environment, and the mass ratio of PCNs in the soil samples and sediment samples ranged from 95.9 to 702 and 56.2 to 75.0 ng·kg-1, respectively. The Low chlorinated pollutants(MO-CNs and Di-CNs)were the main pollutants with the percentage 58.5%, the second was the Hexa-CNs with percentage 10.5%. The main source of PCNs pollution is the electronic waste incineration process, and the main spread channels of PCNs was the settlement of atmospheric diffusion effect. The research results indicate that the e-waste dismantling field has obvious PCNs pollution impact on surrounding environment, especially the low chlorinated PCNs pollution, and the key to control the PCNs pollution of e-waster dismantling is to control electronic waste incineration disposal process.
