电子垃圾拆解地多溴联苯醚污染土壤修复技术研究进展

Research Progress of Remediation Technologies for Soil Contaminated by Polybrominated Diphenyl Ethers around the E-waste Recycling Field

电子垃圾在堆放过程中大量多溴联苯醚(PBDEs)释放到土壤中,对动植物生长、农产品安全和人体健康构成严重威胁。介绍了电子垃圾拆解地附近土壤中PBDEs的污染现状,结合国内外研究进展,综述了土壤中PBDEs的吸附/解吸行为,以及PBDEs污染土壤的光化学修复、微生物修复和植物修复等修复技术,并对PBDEs污染土壤修复技术研究的未来发展方向进行了展望。

Lots of polybrominated diphenyl ethers （PBDEs） are released to soil during the process of stac- king of electronic waste. As its high persistance,the content of PBDEs in soil is increasing and PBDEs has been a serious threat to the growth of animal and plant, the safety of agricultural products and human health. This paper introduces remediation technologies of soil contaminated by PBDEs,mainly focusing the remediation efficiency and mechanism of the adsorption and desorption behaviors of PBDEs,photochemical remediation,microbial remediation, and phytoremediation. At the end the paper looks to the development direction of remediation technologies of soil contaminated by PBDEs in future.
