Global Warming and PCBs   2 comments

Greenhouse Effect

Rising global temperatures maybe responsible for more than ascending sea levels and the decline of the polar bear population. A new study shows that warmer temperatures can re-release polychlorinated biphenyls (PCBs) and other persistent organic pollutants (POPs) back into the atmosphere.

Once POPs are cast loose into the environment, they follow a number of paths. Many linger in underwater sediment beds for years after their initial release. The Environment Canada’s Air Quality Research Division recently showed that higher temperatures can aggravate the dormant POPs, causing them to volatilize and sending them into the air. In effect, this would result in higher concentrations of PCBs in our air for us to breathe in. It also means that the released PCBs  may travel great distances, polluting new areas.

  1. You can take the teacher out of the classroom, but you cannot take the teacher out of you, Mary.
    Seriously though, as if we needed one more reason to be terrified of global warming…

  2. Add this to the list of scientific facts that conservative politicians will deny outright. I did enjoy your nerdy graphic though. Thanks for the post.
