摘 要 ：对珠江三角洲4个不同地方的养殖池塘中水样,泥样和不同种类的鱼样分析,结果表明水产养殖中多氯联苯的分布和归趋在不同分配相中有很大差别,水相中含量较低(8.0～2 4 .0 3ng·L- 1 ) ,沉积相中较高(7.32～36 .2 3ng·g- 1 ,干重) ,特别是工业活动频繁的地方,而乡村相对较低。鱼类不同食性对多氯联苯的积累及其同分异构体的分布有很大影响,肉食性鱼类比草食性鱼类积累更多的多氯联苯.其中代表性同分异构体有IUPAC 118,138,81/ 87,15 3,180 ,5 2 ,4 9,99,4 4。珠江三角洲水产养殖中多氯联苯对生态环境的影响相对较低。

Abstract:The concentrations of polychlorinated biphenyls were determined in water, surface sediments and fish from freshwater fishponds in four different sites of Pearl River Delta regions in China. Results showed that the concentrations of polychlorinated biphenyls ranged from 8.0 to 24.03 ng·L~(-1) in water, 7.32 to 36.23 ng·g~(-1) (dry weight) in sediments and 80.01 to 191.66 ng·g~(-1) (lipid weight) in fish. The concentrations of polychlorinated biphenyls in sediments and fish were higher in developed industrial...
