Historical Perspective Past: more products were wood and metal Now: numerous products are plastic or other petroleum-derived materials that are more flammable. High standards for flame retardancy (esp.,CA) Additives needed to prevent plastics, foams, and other new materials from burning so fast. BFRs save lives (e.g., gives people more time to get out of the building)


Sep , &#;&#;Brominated flame retardants (BFRs) are ubiquitous chemicals with large and global industrial use, and many of them are still produced in large volumes. Due to this fact, several BFRs are found in quantifiable levels in wildlife as well as in humans (e.g. De Wit, ). However, we still know little about the effects of BFRs in wildlife and in man.
