Distribution of persistent organochlorines in the oceanic air and surface seawater and the role of ocean in their global transport and fate
Article Abstract:
Atmospheric concentrations of organochlorines are higher in the Northern Hemisphere than in the Southern Hemisphere, according to a study undertaken in 1989-1990 of concentrations in air and surface water from several oceans. The study looked at the distribution of these substances, such as DDTs and chlordanes, and considered the role played by the ocean in determining how they are transported. Current organochlorine distribution indicates that their physico-chemical properties and weather conditions determine their behaviour.

Persistent organochlorine residues in air, water, sediments, and soils from the Lake Baikal region, Russia
Article Abstract:
Air, water, sediment and soil samples from Russia's Lake Baikal region were analyzed to determine the level of organochlorine residues such as DDTs, chlordanes, hexachlorobenzenes and polychlorinated biphenyls (PCB). The results indicated that there was a local origin of DDTs and PCBs. Lake water acted as a sink for organochlorines and as a source for PCBs, although PCB volatilization was smaller than that seen in the Great Lakes.

High accumulation of toxic butyltins in marine mammals from Japanese coastal waters
Article Abstract:
Tissues and organs or finless porpoise found in Japanese coastal waters showed high concentrations of butyltin compounds (BTC) particularly in the liver. There were higher concentrations of di-BTC in the liver and blood, suggesting that retention of BTCs is high in the muscle, liver, and blubber and the porpoises have a low metabolic potential to BTCs.
