摘　　要：为了解长期施用畜禽粪肥农田土壤中抗生素残留情况,研究了吉林省黑土区大型养猪场周边长期施用猪粪土壤中3种四环素类抗生素(TCs)的含量特征及其生态风险.结果表明,ΣTCs的平均值为1.31mg/kg,在不同类型土壤中的平均含量为:典型黑土>白浆土>黑钙土.土霉素(OTC)、四环素(TC)和CTC(金霉素)平均含量分别为:0.69mg/kg、0.48mg/kg和0.14mg/kg,检出率为42.86%~71.43%;OTC、TC和CTC在不同类型土壤中表现出不同的分布特征,主要受土壤性质、抗生素性质、畜禽粪便施用量以及施肥年限等多重因素的交互影响;OTC、TC和CTC的风险商分别为3.06、0.85和0.60,OTC处于高生态风险水平.3种TCs不同程度的超过生态毒害效应的触发值,生态毒害风险较高.长期的猪粪还田引起了土壤中四环素类抗生素的累积,并产生了较高的生态风险.In order to understand the antibiotic residues in farmland soil with long-term application of livestock manure,the concentration characteristics and ecological risk of three tetracycline antibiotics(TCs)in soil around large piggery in black soil area of Jilin Province were studied.The results showed that the mean concentration ofΣTCs in soil was 1.31mg/kg,and the average concentrations in different types of soil were:mollisols>lesslve>chernozem.The mean concentration of oxytetracycline(OTC),tetracycline(TC)and chlortetracycline(CTC)were 0.69mg/kg,0.48mg/kg and 0.14mg/kg,respectively,with the detection rate in the range of 42.86%to 71.43%.OTC,TC and CTC showed different distribution characteristics in different types of soil,which were mainly affected by multiple factors such as soil properties,antibiotic properties,application amount and years of livestock manure.The risk quotients of OTC,TC and CTC were 3.06,0.85 and 0.60,respectively,and OTC was at a high ecological risk level.The three TCs exceeded the trigger value of ecological toxicity effect in varying degrees,and the ecological toxicity risk was higher.The long-term application of pig manure resulted in the accumulation of tetracycline antibiotics in soil and high ecological risk.
