摘要
近年来,土壤抗生素和抗性基因污染已成为我国新兴的环境问题,生物炭作为土壤改良剂施用到土壤后会影响抗生素和抗性基因的环境行为.本文从我国土壤中抗生素和抗性基因污染现状和潜在风险出发,概述了生物炭添加土壤对抗生素的吸附、解吸及老化的影响,分析了生物炭特性、土壤类型、抗生素种类,和温度、pH值、共存物质等吸附条件对生物炭添加土壤吸附抗生素的影响,阐述了生物炭添加对土壤中抗生素和抗性基因迁移、消散、生物有效性,以及酶和微生物的影响,并对生物炭控制土壤中抗生素和抗性基因的研究前景进行了展望,拟为土壤中生物炭调控技术的发展提供参考.
In recent years,the soil pollution of antibiotics and antibiotic resistance genes has become an emerging environmental problem in China.Biochar,as soil amendment,has an effect on the environmental behavior of antibiotics and antibiotic resistance genes.Based on the pollution situation and potential risks of antibiotics and antibiotic resistance genes in soils of China,the adsorption and desorption of biochar amendment soil and the effect by aging were summarized.The effect of biochar characteristics,soil type,antibiotic species,and adsorption conditions such as temperature,pH,and coexisting substances on the adsorption of antibiotics on biochar amendment soil were analyzed.The effects of biochar amendment on migration,dissipation,bioavailability of antibiotics,antibiotic resistance genes and enzymes and microorganisms in soils were discussed.The research prospect of biochar controlling antibiotics and antibiotic resistance genes in soils was expected,which would provide a reference for the development of biochar regulation technology in soils.
