Grizzly Bears are under pressure from hunting, habitat loss and declining food supply. In 2005, Raincoast and its partners at the Institute of Ocean Sciences and the University of Victoria, published a paper on an additional concern, the threat from global pollution.

This paper documented the presence of Persistent Organic Pollutants (such as DDT and PCBs) in grizzly bears. It also documented newer chemicals known as brominated flame-retardants. POPs, including flame retardants, are bio-accumulative toxins that act as hormone mimics once inside the body. Flame retardants are currently doubling in the BC environment every four years.

To learn more about our second study, which examines how hibernation affects these chemicals, check out the Grizzly Bear Contaminant Project. Also read Raincoast’s appeal to Environment Canada on the need to ban all forms of flame retardants.
