摘要: |
为了探究长江流域江苏段地表水中有机磷酸酯类(OPEs)化合物的主要来源和环境行为,于2022年5月和12月采集了不同受纳水体的地表水样品,使用超高效液相色谱三重四极杆质谱联用仪(UPLC-MS/MS) 测定并分析了水体中13种 OPEs的分布特征。结果表明,长江流域江苏段地表水13种典型OPEs总质量浓度为74.3 ~4 776 ng/L,平均质量浓度为354 ng/L。干流和饮用水水源地OPEs处于最低质量浓度水平,其次为农田退水,支流OPEs质量浓度较高,污水处理厂OPEs质量浓度最高。除农田退水外,干流、支流、饮用水水源地和污水处理厂冬季OPEs质量浓度较夏季均有所降低。磷酸三(2-氯丙基)酯(TCPP)、磷酸三(2-氯乙基)酯(TCEP)和三苯基氧膦(TPPO)是地表水中最主要的OPEs污染物。污水处理厂是长江流域江苏段地表水中OPEs的最大来源。 |

Abstract: |
In order to illustrate the main source and environmental behavior of organophosphate esters(OPEs) in the surface water of Jiangsu reach of the Yangtze River Basin, we collected the surface water samples from different receiving water, and further determined the distribution characteristics of 13 OPEs by ultra performance liquid chromatography mass spectrometry(UPLC-MS/MS). Results showed that total concentrations of the 13 OPEs in the surface water of Jiangsu reach of the Yangtze River Basin ranged from 74.3 to 4 776 ng/L, with an average concentration of 354 ng/L. OPEs in main streams and drinking water sources were at the lowest concentration levels, followed by agricultural runoff, whereas tributaries had higher concentration of OPEs, and wastewater treatment plants had highest concentration of OPEs. In winter, the OPEs concentration of main streams, tributaries, drinking water sources, and wastewater treatment plants were lower than that in summer. Tris(2-chloropropyl) phosphate(TCPP), Tris(2-chloroethyl) phosphate(TCEP), and Triphenylphosphine oxide(TPPO) were the main OPEs pollutants in surface water. Wastewater treatment plants are the greatest source of OPEs to surface water. |
