土壤中苯并[a]芘生态毒性及植物修复研究进展OA北大核心CSTPCD

Advances of Ecological Toxicity and Phytoremediation of Benzo[a]pyrene in Soil

中文摘要英文摘要

植物修复技术作为一种环境友好型治理措施,以其固碳减碳、成本低、不产生二次污染等特点越来越受到国内外研究者的关注.本文基于苯并[a]芘(BaP)植物敏感性低且富集能力强的生态毒性特征,比较了不同植物种类的修复效率,梳理了当前现有植物修复技术的机理,归纳了植物修复的影响因素,并基于植物类别、污染物特征和土壤性质对植物修复的影响,提出可通过添加土壤改良剂、接种植物内生菌等强化措施提高植物修复效率,进而实现土壤中BaP污染修复技术的"零碳排放".

Phytoremediation technology,as an economic and environmentally friendly treatment method,has attracted increasing attentions from researchers at home and abroad due to its characteristics of carbon fixation and reduction,low cost,and no secondary pollution.Based on the ecological toxicity characteristics of benzo[a]pyrene(BaP)to plants,which have low sensitivity and strong enrichment ability,this paper compared the remediation efficiencies of different plant species,reviewed the mechanism of current phytoremediation technology,and summarized the factors influencing phytoremediation.Based on the effects of plant types,pollutant characteristics and soil properties on phytoremediation,it proposed that the efficiency of remediation could be improved by adding soil amendments and inoculating endophytic bacteria.Thus,the"zero carbon emission"approach of remediation technology for BaP pollution in soil can be realized.
