【摘要】 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。更多还原

【Abstract】 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 5.17 μg /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.更多还原
