DDT and DDE observations Iwataetal(1993)determinedconcentratonsofDDT in in the air and surface water from various oceans in 1989-1990. The routes of the ship cruises among others covered the Chukchi Sea, Bering Sea, Gulf of Alaska, North Pacific, East China Sea, South China Sea, North Atlantic ocean, Bay of Bengal, and the Southern ocean. 

For DDE predicted surface ocean concentrations are overestimated in the Gulf of Alaska, the Bering Sea, the Chukchi Sea, and the North Atlantic. In all of these regions also the atmospheric concentration was overestimated. This indicates that the strong overestimation in these regions is caused by enhanced deposition from the atmosphere, and amplified by low volatilisation due to low mean surface temperatures. Also in the East China Sea and in the Gulf of Mexico modelled surface...

When compared to other cetaceans, PCB residues in blubber of harbor porpoises (Phocoena phocoena) from the Black Sea showed a measurable sexual difference. PCB concentrations were lower in older female porpoises possibly due to lactational transfer to their calves, while in males the PCB concentrations were positively correlated with increasing age (Tanabe et al. 1997). In stellar sea lions (Eumetopias jubatus), the transfer rate of PCBs through lactation was estimated at 80% of the total body PCB burden of adult females (Lee et al. 1996). PCB concentrations in liver of the stellar sea lion from the Bering Sea increased with increasing age and correlated positively with those of blubber (Lee et al. 1996). In ringed seals (Phoca hispida) from the Russian Arctic, lactational transfer of PCBs was estimated at 25% of whole-body burden in the mature female (Nakata et al. 1998), or about one third that of stellar sea lions. In grey seals (Halichoerus...

Here is what we now know about the prevalence of PSP in Alaskan waters ( ). We have recently conducted surveys in southeast Alaska and the Bering Sea - the two regions of most obvious economic potential - on the presence of PSP-producing dinoflagellates. 

While PSP-producing organisms are present in this area, they appear to be less widespread than in southeast Alaskan waters, a finding consistent with the commercial shellfish survey findings in the late 70 s. Although the potential for PSP problems in these centers clearly exists, it seems that - unlike southeast Alaska - PSP will not preclude commercial exploitation of the Bering Sea shellfish resource. 

Even species that are not known to produce bioactive metabolites may have a large environmental impact, such as Emiliania huxeleyi. This haptomonad protist blooms periodically in the Bering Sea at the detriment of diatoms, disruptii the food chain with massive death of migratory birds and fish losses. Mnemiopsis leidyi is another major such problem this comb jelly has invaded the Black Sea, subtracting zooplankton to fish.
