The residue of new organic pollutant antibiotics in the environment and their risks to the ecological environment have become important research issues at home and abroad. China is the largest country of antibiotic production and antibiotic use. Tetracycline antibiotics (TCs) have been used in large quantities, and they also have the highest residue in animal manure. Tetracycline antibiotics in animal manure are easily accumulated in the soil, and disturb the soil microbial community; furthermore, they are absorbed by crops and remain in agricultural products, thereby threatening human health and ecological security. At present, the pollution of antibiotics in animal manure and soil of southwest China has not been reported. An investigation and analysis were conducted to evaluate the environmental ecological risks of three agricultural tetracycline antibiotics [oxytetracycline (OTC), tetracycline (TC), and chlortetracycline (CTC)] in livestock manure of large farms and soil of main vegetable base in chongqing. The results showed that the average contents of OTC, TC, CTC, and TCs ∑TCs in pig and chicken manure in 2014 was 13.05, 91.81, 62.48, 167.34 mg ·kg |
