"Indiana University scientists have found chemical flame retardants in
the blood of pet dogs at concentrations five to 10 times higher than in
humans, but lower than levels found in a previous study of cats.
"Their study, "Flame Retardants in the Serum of Pet Dogs and in their Food," appeared in April 2011 in the journal Environmental Science & Technology.
Authors are Marta Venier, an assistant research scientist in the School
of Public and Environmental Affairs, and Ronald Hites, a Distinguished
Professor in SPEA.
"Venier and Hites explore whether pets could serve as "biosentinels"
for monitoring human exposure to compounds present in the households
that they share. Dogs may be better proxies than cats, they say, because
a dog's metabolism is better equipped to break down the chemicals.
"The study focuses on the presence of polybrominated diphenyl ethers
(PBDEs) in the blood of dogs and in commercial dog food. PBDEs have been
widely used as flame retardants in household furniture and electronics
equipment. The compounds can migrate out of the products and enter the
