The importance of uptake from food for the bioaccumulation of
While they were intended to improve fire safety, one form — polybrominated diphenyl ethers, or PBDEs — has proved harmful to human health, specifically our hormonal systems. Although the use of PBDEs has been restricted in Canada since 2008, older household electronics and furniture with these compounds are still in use. While the Centers for Disease Control points its finger at dietary sources of PBDEs, the Silent Spring Institute published a paper in 2008 claiming that house dust is a more significant source of contamination than diet. PBDEs have been measured (and found to bioaccumulate) in fish. Mothers pass their PBDE loads to their infants through breastfeeding, as PBDEs are found in breastmilk. There are no known natural sources of PBDEs, except for a few marine organisms that produce forms of PBDEs that contain higher levels of oxygen (ATSDR 2015). PBDEs are structurally similar to polychlorinated biphenyls (PCBs).

Whereas food is the main source of most of the persistent pollutants that people take up—including polychlorinated biphenyls (PCBs), mercury, and pesticides such as DDT—study after study suggests that consumer products are the main sources of PBDEs that Moreover, as a result of widespread environmental contamination, PBDEs are now also detected in common foods, including meat, fish and dairy products (Schecter 2006), which are secondary sources of exposure. Researchers at Duke and Boston Universities have taken a close look at the role of household sources of PBDEs in the measurements in In the era of "fake news" and mass misinformation, finding a reliable news source can prove tricky at times.
PBDEs are a group of synthetic organic chemicals with no known natural sources in the environment, except for a few marine organisms that produce forms of PBDEs that contain higher levels of oxygen. Commercial decaBDE and octaBDE
Polybrominated diphenyl ethers, or PBDEs, are widely used in industry due to their flame-retardant properties. Although they are useful, these substances accumulate in the environment, including the St. Lawrence River, and questions are being raised about their potential impacts. Using either method, our models employ consumption of food as a proxy for consumption of PBDEs in food, another source of exposure misclassification.

Some research has shown that PBDEs accumulate in fatty tissue. To possibly reduce dietary consumption of PBDEs choose lean meat and poultry cuts and low-fat dairy products. Avoid farmed fish, such as salmon, which has been shown to have particularly high PBDE levels, and choose wild fish when possible. Sources: greensciencepolicy.org PBDEs are found in human breast milk, blood, fat, household dust, indoor air, fish, wildlife, birds, beef, dairy products, and sediments. Toxicity and health effects The potential health effects from exposure to flame retardants include cancer, endocrine and reproductive effects, and neurological and developmental disorders.

A secondary objective of the study was to investigate the "urban pulse" effect postulated by Harrad and Hunter (2006) which suggests that urban areas are sources of PBDEs to remote regions. Some research has shown that PBDEs accumulate in fatty tissue. To possibly reduce dietary consumption of PBDEs choose lean meat and poultry cuts and low-fat dairy products.
