【摘要】 本文采用Chromosorb-106大孔树脂吸附,用CS₂洗脱,用玻璃毛细管气相色谱分离,用色谱-质谱-计算机联机定性等方法,对金沙江（渡口市江段）水中痕量挥发性有机污染物进行了分析。共检测出97个有机化合物,并对其中50种化合物取得了181个定量数据,单个化合物的最大浓度为0.4ppb,平均浓度36ppt。经与国内外某些江湖河以及人们迄今所知的有机化合物的毒性比较,该江段水中挥发性有机物污染的程度是较轻的。更多还原

【Abstract】 The volatile organic pollutents in water of DuKou Segment of Jinsha River were analyzed by capillary GC-FID and capillary GC-MS methods. The water samples were first enriched by chromosorb-105, then the enriched samples were eluted with CS2. 97 organic compounds were detected from thesamples with quantitativetive data for 50 compounds therein. The maximum concentration of individual compounds is 0. 4 ppb and the average concentration for the 50 compounds is 36 ppt. It is not serious as compared with other rivers reported in the world.更多还原
