| 摘 要： | 本文以黄河(兰州段)为研究对象,对其流域的4个排污点的水样和6个断面各个介质(包括水体、悬浮颗粒物和沉积物)中壬基酚聚氧乙烯醚(NPnEO)及其降解产物壬基酚的污染进行调查。结果表明,4个排污点水样中分别含有浓度不等的NP;6个断面采样点中,大分子的NPnEO(n>2)在各个介质中均未检出,水样中NP在0.24~2.1μg/L之间,NP1EO在0.060~0.35μg/L之间,NP2EO在0.039~0.26μg/L之间。

| Abstract: | This article takes the Yellow River(Lanzhou section)as the research object,and analyzes the water samples of 4 sewage points and 6 sections of each medium(including water body,suspended particulate matter and sediment)in the watershed of the Yellow River(NPnEO).and its degradation product nonylphenol pollution to be investigated.The results showed that the water samples at the 4 sewage discharge points contained NPs with different concentrations;in the 6 cross-section sampling points,the macromolecular NPnEO(n>2)was not detected in each medium,and the NP in the water samples is between 0.24~2.1μg/L,NP1EO is between 0.060 and 0.35μg/L,and NP2EO is between 0.039 and 0.26μg/L. |
