Abstract:

Antibiotics play an important role in human health care and livestock and aquaculture production, however, the environmental occurrence and ecological risks caused by the widespread use of antibiotics have also attracted wide attention. This paper analyzes and summarizes the research progress on the pollution characteristics of antibiotics in surface water, soil, animals and plants in China during the last 10 years. We founded that: ① sulfonamides (SAs), quinolones (QNs), macrolides (MLs) and tetracyclines (TCs) were detected in varying degrees in surface water and sediment, and the antibiotics pollution in Hai River, Liao River and Pearl River were relatively severe; ② The agricultural soil was contaminated by antibiotics with varying degrees, and the primary contaminant factor were QNs and TCs, the antibiotics pollution in the agricultural soil in North China and Pearl River Delta was serious. ③ The antibiotic residuals were also detected in fishes and vegetables, and the primary pollutant was QNs. In the future, the monitoring of antibiotics pollution in sediment, faces of livestock and poultry, soil and vegetables should be further enhanced, especially the migration and transformation of antibiotics in water-sediment system, faces-soil system and soil-plant system should be thoroughly studied, to accurately understand the environment behavior of antibiotics and to provide a scientific basis for the assessment of ecological risk of antibiotics.
