中文摘要:

      利用超临界流体萃取与热脱附两种样品预处理方法的优势互补,与气相色谱分析相结合对太湖水体中不同沸点有机污染物进行了分析,发现太湖水中除了烃类污染物外还存在大量含氮有机污染物.其分布表明入湖河道中排放的工业污染物的流入是导致太湖水富营养化的一个重要因素.

英文摘要:

      The organic pollutants in Taihu Lake were determined by gas chromatography. In order to analyze the pollutants with a wide range of boiling points, Supercritical Fluid Extraction and Thermal Desorption were used for the sample preparations. Beside the hydrocarbons, the nitrogen containing compounds were found as the important organic pollutants in Taihu Lake. It can be seen from the distribution of the pollutants that the industrial pollutants from the river adjacent to Taihu Lake is one of the important reasons caused the eutrophication of Taihu Lake.
