摘要
近年来药物和个人洗护用品(PPCPs)以及内分泌干扰物(EDCs)等新兴污染物频频检出,引起人们高度关注。众多研究表明,这些新兴污染物已经广泛分布在河流、湖泊、海洋、土壤、沉积物和地下水等环境介质中,而这些物质具有不易降解特性,加之不断排入水体环境,在水体环境中呈现"假持续存在"状态,对生态环境和人体健康造成诸多的不良影响。本文首先简述了以PPCPs和EDCs为代表的新兴污染物在环境中的来源、传播、分布和去除技术,并以表格形式综述了PPCPs和EDCs在各地区的污染现状。最后介绍了生物炭在去除PPCPs和EDCs上的研究现状和进展,分别通过生物炭制备原料、热解温度、改性或活化方式、溶液pH、离子强度和干扰物等因素综述了其对生物炭吸附PPCPs和EDCs的影响,并在最后做出总结和展望,以期能给今后生物炭在去除PPCPs和EDCs等新兴污染物上的相关研究和实际应用提供更多思路。
In recent years,emerging contaminants such as PPCPs(pharmaceuticals and personal care products)and EDCs(endocrine disrupting chemicals)have been frequently detected in the environment,which has risen high concern.Many researches have shown that these emerging contaminants are ubiquitous in environmental media such as rivers,lakes,oceans,soil,sediments,and groundwater.Due to continuously discharged into the environment and hardly degradable characteristics,these emerging contaminants show a“pseudo-persistent”state in the water environment.These emerging contaminants cloud cause plenty of adverse effects on the ecological environment and human health.In this paper,the occurrence,fate distribution,and removal technologies of emerging contaminants represented by PPCPs and EDCs in the environment are briefly discussed.The distribution of PPCPs and EDCs in various countries and regions are summarized.At last,the present research situation of the removal of PPCPs and EDCs by biochar was introduced.The impact factors such as feedstock for biochar preparation,pyrolysis temperature,modification or activation methods,initial solution pH,ionic strength,and interferents were discussed.Finally,a summary and prospect were made to provide more ideas for the related research and application of biochar for emerging contaminants removal such as PPCPs and EDCs.
