【Abstract】 In January of 1990 we collected 20 sets of water samples, 2 sets of bottom samples, 4 sets of biological samples and 1 set of ice and snow sample from the adjacent waters of the Great Wall Station, Antarctica, and performed the determination of organochlorine pesticides in these samples in May of the same year. The results of the determination indicate that DDT and BHC (benzone hexachloride) were present to varying degrees in water, bottom sediments, bodies of organisms as well as in ice and snow in the adjacent waters of the Great Wall Station, Antarctica.更多还原
