This article is hardly evidence. In fact it's hardly an article. It consists of 8 sentences with no real evidence provided.
I'm also questioning the validity of the study. "Heidi N. Geisz and colleagues estimate that up to 2.0-8.8 pounds of DDT are released into coastal waters annually along the Western Antarctic Ice Sheet from glacial meltwater." While that sound like a lot of material, 2 to 8.8 lbs over a year, in the big picture that is this area we're talking about thousands of miles of territory. There's more dangerous waste producing the batteries for hybrid cars.
I think this is another case of the polar bears are dying off, that's why the population has doubled again.

You may be correct, BB64 - We'll have to wait until the June 1 issue of the journal to see what the article actually says and what the data are.

Done the recommended reading and still think much is hype-If those countries want DDT sprayed in houses it seems they can do it. The best articles were Wikipedia and Alternet; loads of info about differing conditions and what works where and why.
On the flip side 8 pounds of DDT a year in the Arctic doesn't seem like much. Our cow got a couple sprayers-ful each summer.
