| 中文摘要: |
| 采用HPLC MS/MS法监测长江南京段横断面水、水源水、出厂水中12种有机磷酸酯类化合物（OPEs）残留，考察其分布特征及自来水厂对其处理效果。结果表明：12种OPEs在采集的横断面水和水源水水样中8种被检出，自来水出厂水水样中除TEHP外其余11种OPEs均为检出，OPEs暴露于水源水与地表水程度相似；除TCPP、TDCP、TCEP浓度出现降低外，其余OPEs浓度水平均未出现明显的处理效果；生态风险评估显示长江南京段横断面水、水源水、出厂水主要检出物质OPEs的风险熵值均低于1，表明不具有环境生态高风险。 |

| 12 kinds of organophosphate ester (OPEs) residues in cross section water at Nanjing section of Yangtze River, source water and tap water was determined by using high performance liquid chromatography mass spectrometry (HPLC MS/MS), their distribution characteristics and the treatment effect by the waterworks were investigated. The results showed that 8 kinds of OPEs were detected in cross section water and source water samples，all kinds of OPEs except TEHP were detected in tap water samples. The exposure degree of OPEs in source water and tap water were similar. Except for TCPP, TDCP, and TCEP whose concentration declined, no significant treatment effect achieved on the concentration of other OPEs. The ecological risk assessment showed that the risk quotients of the main detected OPEs in cross section water, source water and tap water were all lower than 1, indicating no high risk of eco environment. |
