Study finds increasing atmospheric concentrations of new flame retardants
Date:12/14/2011

arine mammals in Hong Kong and household dust and furniture foam in the U.S.

As would be expected, the IU researchers found the largest concentrations of TBB and TBPH in atmospheric samples collected in urban areas: Chicago and, especially, Cleveland. But the compounds were also detected in about half the samples from remote sites at Sleeping Bear Dunes and Eagle Harbor in Michigan and Point Petre in Ontario, Canada. They also were detected at rural Sturgeon Point, N.Y.

TBPH was detected more frequently and in higher concentrations than TBB. The concentrations are similar to those reported previously by Hites and Venier for PBDEs at the Great Lakes sites, suggesting the newer-generation flame retardants may be replacing their predecessors in the environment.
