Dirty-Dozen List of POPs Expanded

While most of the additions are pesticides or related to pesticide manufacture, several of the additions have specific relevance to the building industry. Both the penta and octa forms of polybrominated diphenyl ether (PBDE) flame retardant are included. These were previously in widespread use for flexible polyurethane foams and plastic housings for electronic equipment, respectively, but have not been made since about 2004, when Great Lakes Chemical Company ceased production (see

EBN June 2004 for more on PBDEs).
