Report: Toxins found in whales bode ill for humans http://apocadocs.com/s.pl?1277751618
Sperm whales feeding even in the most remote reaches of Earth's oceans have built up stunningly high levels of toxic and heavy metals, according to American scientists who say the findings spell danger not only for marine life but for the millions of humans who depend on seafood.
A report released Thursday noted high levels of cadmium, aluminum, chromium, lead, silver, mercury and titanium in tissue samples taken by dart gun from nearly 1,000 whales over five years. From polar areas to equatorial waters, the whales ingested pollutants that may have been produced by humans thousands of miles away, the researchers said.... The researchers found mercury as high as 16 parts per million in the whales. Fish high in mercury such as shark and swordfish -- the types health experts warn children and pregnant women to avoid -- typically have levels of about 1 part per million.... "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.
