Turns out your collection of neon-colored silicone bracelets have a use beyond showing support for a fallen-from-grace cyclist's non-profit after all. The material can actually trap pollutants you might be exposed to during the course of your day, according to a study by Oregon State University. Specifically, OSU was looking for how present fire retardant chemicals were in the households of 92 pre-school children. What'd the researchers find? That somehow, over the course of a week, these kids were exposed to polybrominated diphenyl ethers that aren't being produced domestically anymore.
