PBDEs (Polybrominated Diphenyl Ethers) Analysis

Polybrominated diphenyl ethers (PBDEs) and polybrominated biphenyls (PBBs) are chemical compounds added to certain products to reduce the likelihood of products igniting. Finished products containing polybrominated diphenyl ethers (PBDE) are furniture foam fillings, wire insulation, rugs, curtains and upholstery, and plastic cabinets for televisions, personal computers and small appliances.

These chemicals can get into the air, water and soil during their production and leach from products containing these compounds or escape when products containing them deteriorate. They do not dissolve easily in water, stick to particles and settle at the bottom of rivers or lakes. Some polybrominated diphenyl ethers can accumulate in some fish and mammals when they consume contaminated food or water.

People are exposed to PBDEs and PBBs by consuming contaminated food with a high fat content, especially oily fish. Another source of exposure is inhalation of contaminated air or ingestion of contaminated dust. Working in industries that manufacture these chemicals or that make, repair or recycle flame retardant products containing these chemicals may result in exposure.

There is no definitive information on the health effects of PBDEs in humans at low environmental exposures. However, few recent studies have evaluated associations between PBDE concentrations in blood or breast milk and various health effects. Results from some studies have shown an association between PBDE exposure and altered neurodevelopment. In animal studies, these chemicals have been shown to have some effects on the thyroid and liver, as well as on brain development.

When PBDEs enter the environment, the following occurs:

• PBDEs can be released into the air, water and soil where they are produced or used.
• In air, PBDEs can be found both in the vapor phase and in particulate form, eventually settling in soil or water.
• Sunlight can degrade some PBDEs.
• PBDEs do not dissolve easily in water, but stick to particles and settle to the bottom of rivers or lakes.
• Various foodstuffs, including fish, meat and dairy products, have been found to contain low concentrations of PBDE.
• Low brominated PBDEs become bioconcentrated in aquatic organisms.
