摘要
苯并[a]芘(Bap)是一种由5个苯环组成的分布广泛、广受关注、"三致"毒性极强的多环芳烃,也是主要的环境污染物监测对象.Bap在土壤等环境中长期积累,可通过食物链的累积和放大效应威胁人体健康.Bap污染土壤的高效修复迫在眉睫,本文综述了Bap的产生、污染现状与毒性效应、不同修复技术的优缺点.物理/化学方法具有修复周期短、范围广,但成本高且易产生二次污染等特点;生物修复成本低、操作简单、环境效益好,但修复周期长、效果受多因素影响.在实际治理过程中应综合考虑成本和效果,重点关注微生物修复及相关联合修复技术的应用,将为今后开展Bap类有机污染土壤的绿色修复提供科学思路.
Abstract
Benzopyrene(Bap)is a kind of widely distributed polycyclic aromatic hydrocarbon compounds composed of five benzene rings,which attracts much attention.It has strong carcinogenic,teratogenic,and mutagenic effects.Bap is also the main pollutant monitoring object in the environment.Bap accumulates in soil for a long time and thus threaten the human health through the accumulation and amplification effects of food chain.Efficient remediation of Bap-contaminated soil is a matter of great urgency.In this study,the production,current situation of pollution,toxicology,and the advantages/disadvantages of remediation techniques of Bap were reviewed.The physical and chemical methods have the advantages of short operation cycle,wide application range.The cost is relatively high along with the secondary pollution production.On the contrary,bioremediation has the advantages of low cost,easy operation,and environmental green.But bioremediation usually needs a relatively long cycle of restoration,and the efficiency is affected by multiple factors.Therefore,the cost and efficiency should be considered comprehensively in the practical process.In the future,it should be paid attention to the microbial remediation technology and the combined application of relative techniques.This study will provide a scientific thought for the green treatment and remediation of contaminated soil with such persistent organic pollutants as Bap.
