POLLUTION STATUS AND HEALTH IMPACT ASSESSMENT OF ANTIBIOTICS IN ENVIRONMENTAL - AND DRINKING WATER

The problem of antibiotics pollution in environmental water and drinking water has attracted the attention of environmental protection departments and all walks of life. At present, antibiotics have been widely detected in many water systems, and the concentration range is from ng/L to pg/L. In this paper, a method for the analysis of antibiotics in water by high performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS) was established. Then, the risk quotient (HQ) of antibiotics in wastewater treatment plant effluent and river water was calculated and studied. The results showed that some antibiotics did not cause direct ecological risk. Finally, the health risk assessment of environmental water and drinking water was carried out. The results showed that the non carcinogenic risk caused by antibiotic pollution in the reservoir was far lower than the acceptable risk level, even far lower than the negligible risk level, indicating that the residues of these antibiotics in the drinking water would not pose significant non carcinogenic harm to human body.
