| Abstract: | The levels of DDT and its metabolites found in the blubber of 29 minke, 6 fin and 1 sei whale landed at the Durban whaling station in 1974 were on average much lower than those found in baleen whales from the North Atlantic, but of the same order as those measured from the Antarctic and North Pacific. In 12 sperm whales examined at Durban the levels of DDT and its metabolites in the blubber were substantially lower than in any other locality so far examined, including the Antarctic, but this may partly reflect the comparative youth of the animals sampled. Low levels of Dieldrin were found in some minke whales only. No PCB could be detected in any of the whales examined. |
