| 摘 要： | I~IOXAmong a large number of man-made chemicals, organochlorines such as DDTs, HCHs (hexachlorobenzene) are of great concern due to their highly bioaccumulative nature and toxic biological effects. These chemicals are persistent in nature, can biomagnify in the food web and imalvarious toxic effects in marine mammals. They can cause abnormal thyroid function in Herringgull, feminising in western gull, and can impair Avian reproduction, among other deleterious effects (Carmichael, 1988).Th…

| Abstract: | The Concentrations of 18 organochlorine pesticides and 12 polychlorinated biphenyls (PCBs) in water, porewater and sediments from the Xiamen Harbour were analyzed quantitatively. It shows that, the levels of all organochlorine insecticides varied from 6. 60 to 19 .6 ng/dm3 (in water), 11. 9-78. 5 ng/dm3(in porewater) and not detected (ND) - 0. 58 ng/g dry weight (in sediments), and those of total DDTs were in the range ND - 0. 06 ng/g dry weight. Concentrations of PCBs and in- secticides in porewater were higher than in surface water, due to the higher affinity of these hydrophobic compound for sedimentary phase than to water. It implies there would be a potential flux of pollutants from sediments to overlying water. Compared with the concentrations of these pollutants measured in the Xiamen Harbour in 1993, it is one to several magnitude order lower, which suggests their inputs have been decreased in recent years and possible degradation of these compounds. The levels of these pollutants were also compared with other estuaries. |
