Toxaphene and other persistent organochlorine pesticides in three species of albatrosses from the north and south Pacific Ocean.

摘要: Toxaphene and other persistent organochlorine (OC) pesticides (chlordane-related compounds ( SCHL), DDT-related (SDDT), hexachlorocyclohexanes (SHCH), tris(p-chloro-phenyl)methane, hexachlorobenzene, octachlorostyrene, diel- drin) were determined in fat of Laysan albatross (Diomedea immutabilis) eggs blackfooted nigripes) from the central north Pacific Ocean. The HCH isomers chlordane- also northern royal sanfordi) collected New Zealand. was detected samples at mean 6 standard deviation (SD) levels ranging 243 61 ng/g wet weight to 1,020 237 albatross. These higher than SCHL SHCH but lower SDDT. In albatross, toxaphene major OC pesticide, averaging 513 two pooled compared with 293 for Two congeners, octachloroborane B8-1413 (Parlar 26) nonachlorobornane B9-1679 (P50), com- prised about 38% total both species. All present significantly exception SHCH, dieldrin, octachlorostyrene.
