Levels of PBDEs rise, new research shows<br />

"Everyday foods consumed by Canadians -- such as salmon, ground beef, cheese and butter -- are laced with chemical flame retardants, according to research commissioned by The Globe and Mail and CTV News.<br />
<br />
In fact, the research found that Canadian foods are among the most contaminated with polybrominated diphenyl ethers in the world, with levels up to 1,000 times higher than those found in tests in European countries.<br />
<br />
PBDEs are a class of about 25 chemicals that are used as flame retardants in foams, textiles and plastics. They are ubiquitous in modern homes, with the chemicals leeching out of furniture, rugs and electronic products, such as televisions and computers. It is not known exactly how PBDEs migrate from such products into human tissue, but they have been found in industrial sewage sludge, in wildlife and in fatty foods such as meat and fish.<br />
<br />
It is unclear what impact the regular absorption of PBDEs has on human health. Nor have scientists established safe levels for the chemicals in humans. <br />
<br />
But scientists do say that research conducted on animals -- which suggests these chemicals can impair memory, cause learning disabilities and alter thyroid hormone levels -- is disquieting and should raise red flags. <br />
<br />
"These are persistent toxic chemicals . . . and certainly it is undesirable to have these toxic chemicals in our food supply," said Arnold Schecter, a professor of environmental sciences and public health at the University of Texas, who has done pioneering work on PBDEs.<br />
<br />
Research done last year on a group of B.C. women found high levels of PBDEs in their breast milk, but the source was unclear....."<br />
<br />
Here are some figures qunatifying amounts in various foods:<br />
<br />
The following foods were tested for the presence of polybrominated diphenyl ethers, or PBDEs, chemicals widely used as flame retardants. Animal experiments suggest PBDEs may be linked to learning difficulties and thyroid problems.<br />
<br />
Parts per trillion <br />
Farmed rainbow trout 3,638 <br />
Farmed Atlantic salmon 1,942 <br />
Extra-lean ground turkey 450 <br />
Butter 384 <br />
Sausages 242 <br />
Pork chops 56 <br />
Medium ground beef 32 <br />
