|The pollution status and ecological risk assessment of 28 antibiotics in 16 sites of East Lake were analyzed by UPLC-QQQ-MSD. 20 kinds of antibiotics were detected at different sites. The average detection concentration from high to low as quinolones, chloramphenicol and sulfonamides. The concentration of antibiotics showed high in the south and low in the north, high in the east and low in the west in this study. Considering that there are many agricultural planting, aquaculture and livestock and poultry farms around the sampling sites in the south of East Lake and their potential antibiotic pollution to East Lake, it is confirmed that human activities are closely related to antibiotic pollution. The RQ values were used to evaluate the ecological risk assessment, the results showed that oxolinic acid and flumequine were identified as low risk in the south of East Lake, while the risks of other antibiotics can be ignored.
