Chemical makers and environmental advocates are praising a move last week by governments from around the world to end production and use of the flame retardant hexabromocyclododecane (HBCD).

Quote from article:
"Published studies show that HBCD, which has been widely used in polystyrene foam insulation for buildings, is toxic to aquatic organisms, can disrupt thyroid hormone in laboratory animals, and persists in the environment."

"Countries approve controls on several chemicals
More than 120 countries reached an agreement on stricter export controls for several chemicals and a phaseout of flame-retardant chemical hexabromocyclododecane. Chemicals that will fall under more stringent export controls include insecticide Azinphos-methyl, flame retardants PentaBDE and OctaBDE, and fabric protector PFOS."

Thanks JL for the link to the very informative article by Ms. Hogue. This is good news but was sorry to read that the parties to the treaty set 2019 as the goal for complete elimination of HBCD, Read and noted.

You are welcome John. You cannot currently send a star to John because you have done so within the last day.

I am happy to see a POP gone, but there was a reason why it was so widely used. I really hope there is a more environmentally friendly substitute ready to go. The support from manufacturers tells me this is probably the case. :)

It looks as if they have a good plan.

thanks for the post my friend......very serious problem, just to elaboratew a little more...

Hexabromocyclododecane (HBCD or HBCDD) is a brominated flame retardant. It consists of twelve carbon, eighteen hydrogen, and six bromine atoms tied to the ring. Its primary application is in extruded (XPS) and expanded (EPS) polystyrene foam that is used as thermal insulation in the building industry. HBCD is highly efficient in this application so that very low levels are required to reach the desired flame retardancy. Typical HBCD levels in EPS are 0.7% and in XPS 2.5%. At present, according to BSEF, the brominated flame retardant industry panel, HBCD is the only suitable flame retardant for these applications. Any other flame retardant would likely need higher load levels in the polystyrene foam. Other uses are upholstered furniture, automobile interior textiles, car cushions and insulation blocks in trucks, packaging material, video cassette recorder housing and electric and electronic equipment. According to UNEP, “HBCD is produced in China, Europe, Japan, and the USA. The known current annual production is approximately 28,000 tonnes per year. The main share of the market volume is used in Europe and China....

Due to its persistence, toxicity, and ecotoxicity, a global ban on HBCD is currently being considered under the framework of the Stockholm Convention on Persistent Organic Pollutants.It was proposed banned by the Stockholm Convention in October 2012, final descision will be taken May 2013. HBCD is also included on the list of substances added to a proposal to revise the RoHS (Restriction of Hazardous Substances) directive. There is a large and increasing stock of HBCD in the anthroposphere, mainly in EPS and XPS insulation boards.
The Persistent Organic Pollutants Review Committee of the Stockholm Convention announced on 2012-10-25 that it is recommending the listing of hexabromocyclododecane in Annex A to the Convention with specific exemptions for production and use in expanded polystyrene and extruded polystyrene in buildings

Thank you for the important information. It's about time! Thanks to those who posted such informative comments. I'm afraid I have no background in chemistry. However, the very idea of putting these chemiclas in children's and babies' clothes makes no sense. In laymen's terms: if you can't pronounce it; it's probably not good for you're children or the environment. (n, p, t)
