摘　　要：兽药抗生素主要用于动物疾病的预防和治疗。目前多用于生长促进剂和饲料添加剂,在现代畜牧业中应用广泛。其残留物进入土壤后,会发生吸附、迁移、降解等一系列转化过程。这些行为决定了抗生素在环境中的潜在效应,如诱使微生物产生抗性基因,改变土壤微生物多样性或污染地下水乃至地表水等。本文综述了近年兽药抗生素在土壤中行为的研究进展,并对今后的研究方向进行了展望。Veterinary antibiotics are extensively used as prophylactics,theraputical medicines,growth promotors and additives in livestock production.The antibiotics are excreted mostly unmetabolized in feces and urine after administration to livestock.After entering into the soil,the residues undergo some processes of sorption,transportation,degradation and so on.These behaviors will determine the potential effects of antibiotics in the soil such as inducing antibiotic-resistance genes,disrupting indigenous microbial populations or contaminating groundwater,and even surface water.Based on the recent researches developments in the recent years,a summary is presented on the performance of veterinary antibiotics in the soil and directions of future research are recommended as well.
