Abstract

Abstract

In order to evaluate the pollution status and ecological risks of antibiotics in the surrounding water bodies of livestock and poultry breeding areas in Dalian, a large-volume direct injection/liquid chromatography-mass spectrometry method was established to analyze the occurrence concentration, time and space distribution characteristics of 22 antibiotics in 6 categories in these areas, and the risk quotient method was used to carry out the ecological risk assessment. The results showed that: 1)19 kinds of antibiotics were detected in different degrees in the surrounding water of livestock and poultry breeding areas, and the detected concentration was 2 to 2590 ng/L; 2)The distribution characteristics of antibiotics in the surrounding water of livestock and poultry breeding areas showed a squence of the surface water＞the pond water＞the groundwater, and the antibiotic concentration was higher in the dry season and lower in the wet season, and the spatial distribution of different types of antibiotics was significantly different; 3)Roxithromycin, dehydrated erythromycin, norfloxacin and sulfamethoxazole in the surrounding water bodies of livestock and poultry breeding areas had high ecological risks, while the other species had medium and low risks. The research showed that the antibiotic content in the surrounding water of livestock and poultry breeding areas in Dalian was moderately high, and macrolide and sulfonamide antibiotics were the main risk factors.
