TUESDAY, Dec. 20 (HealthDay News) -- Increasing concentrations of pair newer generation flame-retardant chemicals were detected in atmospheric samples collected in the Great Lakes locality between 2008 and 2010, a recently made known study indicates.

The chemicals are used to dwarf flammability in various products, including electronic devices, textiles, plastics, coatings and polyurethane foams. They are 2-ethylhexyl tetrabromobenzoate [TBB] and bis(2-ethylhexyl) tetrabromophthalate [TBPH].

TBB and TBPH are included in arising from traffic mixtures introduced in recent years to be a substitute for polybrominated diphenyl ethers (PBDEs), widely used warmth retardants taken off the market for the reason that they can leak from products into the environment.

In this study, Indiana University researchers analyzed 507 breeze samples collected at six locations without interrupti~ the shores of the Great Lakes.

"We determine judicially that the environmental concentrations of (TBB and TBPH) are increasing especially rapidly," Professor Ronald Hites, of the School of Public and Environmental Affairs, said in a university news release. "It's scarce to find that concentrations of somewhat compound are doubling within a year or two, which is what we're vision with TBB and TBPH."

The highest concentrations were detected in urban areas, including Cleveland and Chicago. But the chemicals were in like manner present in about half the samples from far off locations in Michigan, New York and Ontario, Canada.

The findings, published in the journal Environmental Science & Technology, move that these newer-generation flame retardants may have ~ing replacing their predecessors in the environment, the researchers before-mentioned.

Previous research has found TBB and TBPH in household dust and furniture foam in the United States, sea-soldier mammals in Hong Kong and sewerage sludge in California.
