Abstract:

Objective To understand the water pollution situation and accumulation of sulfonamide antibiotics in the water source of Dianshan Lake,and provide reference basis for scientific protection of water quality. Methods From January 2021 to December 2022,continuous monitoring of the water quality of Dianshan Lake in Qingpu District of Shanghai City was carried out,with monthly collection of water samples for testing. A total of 600 water samples were collected,conventional indicators were tested using nationally recommended testing methods,and sulfonamide antibiotics were tested using liquid chromatography tandem mass spectrometry,and the data were analyzed. Results The annual temperature in the Dianshan Lake area was between 7-36 ℃,and the water temperature was between 2-26 ℃. The average concentration of permanganate index(CODMn) was (3.14±0.49)mg/L,the average concentration of total nitrogen(TN) was (4.91±1.46)mg/L,and the average concentration of total phosphorus(TP) was (0.08±0.04)mg/L.Thirteen sulfonamide antibiotics could be detected,with sulfamethoxazole having the highest concentration and detection frequency. Conclusion The water quality of Dianshan Lake has improved compared to previous monitoring results and meets the standards for drinking water.
