摘要
应用固相萃取－高效液相色谱法调查了嘉陵江和长江重庆段的壬基酚聚氧乙烯醚(ＮＰｎＥＯ,ｎ＞３)的污染状况．在四月份,长江的Ａ,Ｂ和Ｃ,嘉陵江的Ｄ和Ｅ采样点都测定出了ＮＰｎＥＯ(ｎ＞３)．长江上游Ａ点的浓度最高,为３７．２８μｇ·ｌ－１,嘉陵江的下游Ｄ点的总浓度最低,为７．２１μｇ·ｌ－１．七月的水样中仅在Ａ,Ｄ,Ｅ点检测出ＮＰｎＥＯ(ｎ≥３),其总浓度最高为１．９９μｇ·ｌ－１．但其分解产物ＮＰ的浓度比四月份高．
A solid phase extraction-HPLC method was estabolished to separate residual nonylphenol ethoxylates and their metabolites in environment, the detected limit was 0.004μg·l-1 . The con-centration of NPnEO in Jialingjing river and Yangtes river (Chongqing City section) was detected using this method. NPnEO (n > 3) were detected in all samples with an from 4 to 28 in April, the highest total NPnEO (n >3) concentration was 37.28μg·l-1 in site A, located in the up-stream of Yangtse river, and the lowest concentration was 7.21μg·l-1, loctaed in the downstream of Jialing jiang River. NPnEO (n > 3) were detected only in site A, D and E in July and the highest concentration was only 1.99μg·l-1. However, the breakdown product, NP, was much higher than that in April.
