Polar bears – gender bent in the Arctic – 01/11/2006

    This anomaly of gender-bend has been widely reported in many marine
    This is the part of the article that cought my attention~””the
    chemicals attack the sex and thyroid glands, motor skills and brain
    function.”” Gosh I’m seeing a lot of this kind of health involvement.

    Chemical linked to gender-bender polar bears

    By David Usborne

    One in 50 female polar bears on an Arctic island have male and
    female sex organs, researchers have found, in a study linking
    pollution and flame retardant chemicals used in the Western world
    with dangers to wildlife.

    Scientists from Canada, Alaska, Denmark and Norway say significant
    deposits of flame retardant PBDEs have been found in polar bears,
    especially in eastern Greenland and Norway’s Svalbard islands.

    Studies are still being carried out on what impact the chemicals
    might be having on bears. Tests on lab animals such as mice indicate
    they attack the sex and thyroid glands, motor skills and brain

    There is also evidence that compounds similar to PBDEs have
    contributed to a surprisingly high rate of hermaphroditism in polar
    bears. About one in 50 female bears on Svalbard has both male and
    female sex organs, a phenomenon scientists link directly to the
    effects of pollution.

    “The Arctic is now a chemical sink,” said Colin Butfield, a campaign
    leader for the Worldwide Fund for Nature, which last month indicated
    that killer whales in the Arctic were also suffering from elevated
    levels of contamination with fire retardants as well as other man-
    made compounds.

    “Chemicals from products that we use in our homes every day are
    contaminating Arctic wildlife.”

    The pollutants are carried northwards from industrialised regions of
    the United States and western Europe on currents and particularly on
    northbound winds.

    Contaminated moisture often condenses on arriving in the cold Arctic
    climes and is then deposited, ready to enter the food chain.

    For several years, scientists have observed how the concentrations
    of the pollutants are magnified as they ascend the food chain, from
    plankton to fish and then to marine mammals such as seals, whales
    and polar bears.

    The new study, published in the journal Environmental Science and
    Technology, shows, for instance, that one compound was 71 times more
    concentrated in polar bears than in the seals they normally feed

    Conservationists are especially alarmed by these new findings
    because of the already fragile condition of the Arctic polar bear
    populations, some of which could be devastated before the end of the

    As warming temperatures erode their hunting grounds, polar bears in
    Canada’s western Hudson Bay region, for instance, saw their numbers
    slide from 1100 in 1995 to only 950 in 2004.

    The dangers now posed by the PBDEs are reminiscent of the crisis 30
    years ago over PCBs – polychlorinated biphenyls – a highly toxic
    byproduct of many industries that was also found to be migrating in
    large quantities to the Arctic.

    The dumping of PCBs was swiftly banned. Since 2004, manufacturing
    has stopped in the US of two of the most toxic retardants, called
    penta and octa. Stockpiles of both still exist, however.

    According to Derek Muir, of Canada’s Environmental Department and a
    leader of the new research, there are signs of a slightly different
    retardant, typically used in construction materials and furnishings,
    also showing up in the Arctic and in the bears, called HBCD.

    “It’s a chemical that needs to be watched, because it does
    biomagnify in the aquatic food webs and appears to be a widespread

    The research team tested 139 bears captured in 10 locations across
    the Arctic region. They found that the bears in Norway’s Svalbard, a
    wildlife refuge where all hunting is banned, had 10 times the levels
    of the chemicals than bears in Alaska and four times those in

    Chain reaction

    Scientists believe PBDEs – polybrominated diphenyls – are
    contributing to hermaphroditism in polar bears.

    One in 50 female bears have male and female sex organs on Svalbard

    Researchers say the chemicals used as flame retardants move from the
    Western world and condense in the cold Arctic air.

    The chemicals appear to become more concentrated as they pass up the
    food chain, from plankton to polar bears.

    One compound was 71 times more concentrated in polar bears as in
    seals, the bears’ main food source.
