    Higher house dust levels of PBDE flame retardants (FRs) have been reported in California than other parts of the world, due to the state’s furniture flammability standard. However, changing levels of these and other FRs have not been evaluated following the 2004 U.S. phase-out of PentaBDE and OctaBDE. We analyzed dust collected in 16 California homes in 2006 and again in 2011 for 62 FRs and ...

    Medium chain length chlorinated paraffins, with about 50-58 % chlorine content are used as plasticisers in some paints, varnishes and coatings. They are used at between 4-15 % w/w of the total paint. The main areas of application are mainly for industrial and commercial use and not in the kinds of paints or coatings commonly purchased by consumers.
