摘要:
分析和比较了綦江、一品河和嘉陵江的水体和水体沉积物中2种重金属(铅和镉)和3种有机物(五氯酚、六六六和甲基对硫磷)的质量浓度差异,并基于重金属铅、镉及有机物五氯酚、六六六、甲基对硫磷对这3条河流的水体质量进行了评价.最后,不仅分析了污染物在河流间的差异是否具有统计学意义,而且评价了污染物的水质类别.

Abstract:
In a study reported in this paper, we analyzed and compared the differences in the contents of two heavy metals (lead and cadmium) and three organic compounds (pentachlorophenol, hexacostahdichloromethane and methyl parathion) in the water and sediments of the Jialing River, the Qijiang River and the Yipin River-three main tributaries of the Yangzi River in Chongqing, and evaluated the water quality of the three rivers based on lead and cadmium and pentachlorophenol, hexacostahdichloromethane and methyl parathion. Finally, we not only analyzed the significance of differences in the pollutant contents among the rivers, but also evaluated the water quality categories of the pollutants.
Key words:  the Qijiang River  the Yipin River  the Jialing River  organics  heavy metal  water quality assessment
