摘要
本文对乌鲁木齐河中、上游河段悬浮物中的有机物进行了分析,结果表明:冰川站、英雄桥和青年渠首采样点有机物种类达40余种,总含量分别为1.0,1.14和1.2mg·l^(-1),其中C_(29)烷烃相对含量分别为7.94%,15.49%和18.49%,邻苯二甲酸二正丁酯相对含量分别为30.28%,22.28%和33.75%,乌鲁木齐河中、上游河段受到程度不同的酞酸二酯的污染.
This paper focuses on the analysis of the suspended organic substance in the upper and middle parts of the Urumqi river. The results show that the number of types of organic compounds was more than 40 and the total contents were 1.0, 1.14 and 1.2 mg·l-1 at sampling sites of Glaciological station, Hero bridge and Youth channel, respectively. In details, for example, alkyl accounted for 7.94%, 15.49% and 18.49% of the total organic contents; and 1,2-benzenedicarbonxylic acid, dibutyl ester occupied 30.28 % , 22.28 % and 33.75 % of the total organic contents at three sampling sites. It is suggested that the upper and middle parts of the Urumqi river were polluted by phthalate alkyl esters (PAEs) .
