The EPA is concluding a limited study of air and surface samples at four fake-surface fields and playgrounds that use recycled tires -- the same material used under the Obama family's new play set at the White House.
Although the EPA for years has endorsed recycled-rubber surfaces as a means of decreasing playground injuries, its own scientists now have pointed to research suggesting potential hazards from repeated exposure to bits of shredded tire that can contain carcinogens and other chemicals, according to internal EPA documents.
Not just EPA - there are ADA and ASTM standards for this stuff too.
This bit at Paghat's Garden digs into the whole notion of selling recycling at any cost. "It is just amazing how easily horrific facts can be touted as plusses!" Not saying "don't recycle." Just saying don't do it just because the government says you should or it's good for you or good for the planet. Recycling - Do it for the children... Heh.

You know, I always thought that grass was the most comfortable playground padding. I know, I know, that's crazy talk ...
