The biomagnification of polychlorinated biphenyls (PCB), toxaphene, and the DDT family of metabolites was investigated in the epibenthic Mysis relicta (mysid), the benthic Pontoporeia hoyi (amphipod), plankton, particulate flux, surficial sediments, and Myoxocephalus thompsoni (deepwater sculpin) in southeastern Lake Michigan. DDE was the most strongly biomagnified compound, increasing 28.7 tim...

Concentrations of toxaphene (CHB) and 2-exo,3-endo,5exo,6-endo,8,9,10-heptachlorobornane (B7-1001; Hp-Sed), a major toxaphene component known to be present in the sediment of toxaphene treated lakes, were determined in water, sediment, and fish from 13 lakes to examine the relationship between chlorobornane levels in fish and environmental variables. The lakes were situated in either the boreal...

Organochlorine compounds are known to be atmospherically transported to long distances from their original sources. To understand the influence of California's Sierra Nevada range on the air transport and subsequent distribution pattern of some of these residues within the range, we have chosen salmonid fish as an indicator species. Fish were collected from 10 locations throughout the northern ...

The effect of exposure to different amounts of polychlorocamphene (toxaphene) on the level of cathecholamines (noradrenalin and adrenalin), their precursors (DOPA and dophamine), and a metabolite (vanillylmandelic acid) in tissues (adrenals, brain, heart) and daily urine in white male rats has been studied. It was established that the single administration of 120 mg/kg toxaphene (half the LD50)...
