摘要
对三峡库区重庆段水体有机污染进行了调查研究,发现三峡库区重庆段水体已经受到了有机物污染,其主要检出有机污染物是卤代烃类、氯代苯类、烷烃类、醇类、酮醛类、多环芳烃类和酯类等,与三峡库区成库前相关研究比较,有机物成份存在着一定的变化。对重庆段水体的分析结果显示,重庆段水体枯水期检出有机物数目多于丰水期,而污染程度则恰好相反;其有机物检出浓度分布从和尚山断面至巫峡口断面,呈现出先增大后减少的趋势。对水体的定性定量分析结果显示,重庆段水体检出有机物浓度总体水平都较低,均在相关标准限值范围内,库区蓄水对有机物污染影响并不明显。
The Organic pollution in the Three Gorges Reservoir make a lot of environmentalist keep close watch on it. The Organic pollution in the Three Gorges Reservoir in Chongqing has been researched in this article. Research results shows that the Chongqing reservoir has been polluted by organic pollutants. And the main organic pollutants are hydrocarbons, alcoholic aldehyde, phthalate acid esters and Polycyclic Aromatic Hydrocarbons（PAHs）. The component of pollutants has a little change compared with the condition before water was stored in Chongqing reservoir. Data of the research indicated that there were no obvious changes on the organic pollution of Chongqing reservoir before and after the water was stored.
