Relationship of DDE/ΣDDT in Marine Mammals to the Chronology of DDT Input into the Ecosystem
The DDE/ΣDDT (ΣDDT = DDT + DDE + DDD) ratios in the blubber of North Atlantic pinnipeds and odontocete cetaceans, as determined by several scientists and surveys, are compiled to obtain a biannual mean series. Conversion of DDT to DDE is interpreted as being due not only to the marine mammals but al...
