Is PBDE harmful?

❖ Studies in rats and mice show that PBDEs cause neurotoxicity, developmental neurotoxicity, reproductive toxicity, thyroid toxicity, immunotoxicity, liver toxicity, pancreas effects (diabetes) and cancer (penta and decabromodiphenyl ether).

Why is PBDE toxic?

The toxicity of PBDEs is not as well understood as that of PCBs. PBDEs are endocrine disruptors and neurotoxins. They are believed to cause liver tumors, neurodevelopmental and thyroid dysfunctions.

What do PBDEs do to humans?

Tetra-, Penta-, and Hexa-BDEs are the isomers most commonly found in humans. Based on studies on experimental animals, the toxicological endpoints of exposure to PBDEs are likely to be thyroid homeostasis disruption, neurodevelopmental deficits, reproductive changes, and even cancer.

Are PBDEs banned in the United States?

Brominated flame retardant chemicals, banned in the U.S. since 2004, still pollute the bodies of newborn American babies, according to a new study from Indiana University scientists. Polybrominated diphenyl ethers, or PBDEs, were once widely used in products including furniture foam and electronics.

Is PBDE a carcinogen?

The International Agency for Research on Cancer (IARC) has classified PBDE as a Group 3 carcinogen (not classifiable as to its carcinogenicity to humans) based on inadequate evidence of carcinogenicity in humans and inadequate or limited evidence in experimental animals.

Are PBDEs still used?

Flame retardant manufacturers in the U.S. voluntarily stopped producing the PentaBDE (used in furniture foam) and OctaBDE (used in electronic products) varieties of PBDEs in 2004 and have begun producing alternative flame retardants; however, DecaBDE continues to be produced and used in the U.S., primarily in …

What are PBDEs found in?

PBDEs are found in a variety of consumer products, from TVs and toasters to mattresses and drapes. These chemicals are intended to slow the rate of ignition and fire growth, allowing people more time to escape from a fire or extinguish it.

Where are PBDEs banned?

According to Environment California, since California’s ban of two types of PBDEs in 2003, several states have taken action against these chemicals, including Maine, Hawaii, Michigan, Washington, Oregon, Illinois, Maryland and New York. The European Union passed a ban in 2002.

How do I get rid of PBDE?

What can you do? PBDEs are being phased out of many consumer goods. Avoid purchasing items that still have PBDEs added to them. Instead, use products that are naturally flame-retardant; wool is a good example.

Are PBDEs banned in Canada?

PBDEs have been widely used since the 1970s; however, due to their persistence in the environment, the manufacturing of PBDEs has been banned and the import, use and sale of PBDEs found in commercial mixtures of greatest concern (penta- and octaBDE) have been restricted in Canada since 2008 and in the US since the end …

Is PBDE still used?

Is PBDE banned in Australia?

Commercial Penta- and Octa-PBDE mixtures were banned in Australia in 2005, while HBCDD was banned worldwide in 2013. We investigated PBDE and HBCDD concentrations in serum collected from young children.

What are the levels of PBDEs in serum?

The following PBDEs were detected in greater than 60 percent of participants: BDE-28, BDE-99, BDE-100, and BDE-153. Also, BB-153 was detected in greater than 60 percent of participants. Finding measurable amounts of PBDEs and/or PBBs in serum does not imply that the levels of these chemicals cause an adverse health effect.

How are PBDEs and PBBs harmful to humans?

Another source of exposure results from breathing contaminated air or swallowing contaminated dust. Working in industries that make these chemicals or that make, repair, or recycle products containing these chemicals flame retardants can result in exposure. Human health effects from PBDEs and PBBs at low environmental exposures are unknown.

Which is the highest PBDE in the world?

In the Fourth Report, scientists found that one PBDE, BDE-47, demonstrated the highest levels of the ten different PBDEs measured in the Fourth Report. These levels for the U.S. population are roughly 3 to10 times higher than levels seen in participants of various studies from European countries.

How are PBDEs measured in the human body?

By measuring PBDEs and PBBs in blood serum scientists can estimate the amounts of these chemicals that have entered people’s bodies. In the Fourth Report, scientists found that one PBDE, BDE-47, demonstrated the highest levels of the ten different PBDEs measured in the Fourth Report.
