洪泽湖硝基苯类化合物的污染特征

摘要

The concentration of 10 kinds of nitrobenzene compounds in samples of water, sediment and aquatic biological from 9 point of Hongze lake were measured. The results show that: the total content of nitrobenzene compounds (ΣNBs ) in water samples is from 0. 179 to 5. 17μg/L, the concentration of total nitrobenzene compound in northern and southern Lake District are higher, and the highest concentration is Chenghebei ( S7 ) . The total concentration of total nitrobenzene compound in sediment is 0. 137-4. 50 μg/kg, the concentration of northern Lake area and nearby the lake outlet are much higher, the highest point is Chenghedong ( S6 ) . Total content of nitrobenzene in aquatic organisms of carp, whitefish, catfish, lobster, mussel, snail increased successively.%对洪泽湖水质、底泥及水生生物样品10种硝基苯类化合物的浓度进行了测定，水样中总硝基苯类化合物的含量在0.179~5.17μg/L，北部湖区和南部湖区的总硝基苯类化合物的浓度较高，其中成河北( S7)的浓度最高。底泥中的含量在0.137~4.50μg/kg，北部湖区及出湖口附近形成一个硝基苯类化合物的污染带，其中成河东( S6)的浓度最高。水生生物体内的总硝基苯含量按鲫鱼、白鱼、泥鳅、龙虾、河蚌、螺蛳依次升高。
