AGADIR, Morocco — American scientists who shot nearly 1,000 sperm whales with tissue-sampling darts discovered stunningly high levels of toxic and heavy metals in the animals that they say could affect the health of both ocean life and the millions who eat seafood.
A report Thursday noted high levels of cadmium, aluminum, chromium, lead, silver, mercury and titanium in the mammals, according to samples taken over five years.
Analysis of cells from the sperm whales showed that pollution is reaching the farthest corners of the oceans, from deep in the polar region to "the middle of nowhere" in the equatorial regions, said biologist Roger Payne, founder and president of Ocean Alliance that conducted the research. The whales travel on voyages up to 87,000 miles (140,000 kilometers).
"The entire ocean life is just loaded with a series of contaminants, most of which have been released by human beings," Payne said in an interview on the sidelines of the International Whaling Commission's annual meeting.
"These contaminants, I think, are threatening the human food supply. They certainly are threatening the whales and the other animals that live in the ocean," he said.
