摘要
分析研究了松花江吉林市至三岔河口江段鱼类肌肉中４３种污染物，结果表明：该江段鱼类已受到总汞、甲基汞、铜、锌、镉和铬的轻度污染，尚未受到铅、锰、铁、砷的污染。扶余至三岔河口江段的鱼类食之有异味，肌内中烷烃、芳烃、硝基芳烃、硝基氯苯和挥发酚５类２８种有机污染物的总平均含量和其中的３种促癌或助癌物、６种可疑致癌物以及化工污染的特征性有机污染物──硝基芳烃类的平均含量均比其它江段高。
The paper reports the study results on the 43 pollutants in the muscle of fishes in theSonghua River from Jilin city to Sanchahekou from 1990 to 1992.No pollution of lead,manganese,iron and arsenic and slight pollution of mercury,methylmercury,copper, zinc,cadmium and chromi-um have been found in the fishes. In the river from Fuyu to Sanchahekou,the total average concentrations of 28 organic pollutants classified as hydrocarbon,arene,nitro-arene nitro-chlorobenzeneand volatile phenol as well as the average concentrations of 3 cancer-favor and cancer aid and 6 sus-pected carcinogen and characteristic organic pollutants from chemical industry such as nitro-arene arehigher than those of other sites. Meanwhile the fishes have abnormal tastes.Since the governmentsand relevant departments strengthened the treatment of pollution sources,the level of fish pollutiondecreased and the quality of fishery products have been improved in the river from Jilin to Sanchahek-ou.
