Polybrominated Diphenyl Ethers (PBDE): 1000 ppm (0.1%) Similar to PBBs - added to plastic enclosures to make them difficult to burn. Known human carcinogen that affects the endocrine system. Bis(2-Ethylhexyl) phthalate (DEHP): 1000 ppm (0.1%) (RoHS 3) DEHPs are used to soften PVC and vinyl insulation on electrical wires and in medical tubing.
EFSA was asked by the European Commission to deliver a scientific opinion on polybrominated diphenyl ethers (PBDEs) in food. PBDEs are additive flame retardants which are applied in plastics, textiles, electronic castings and circuitry. PBDEs are ubiquitously present in the environment and likewise in biota and in food and feed.
PBDEs, or polybrominated diphenyl ethers, are a class of fire retardant chemicals. As part of NOAA's Mussel Watch Program, PBDEs are one of 150 different contaminants that are continually monitored by periodically sampling bivalves and sediment at 300 coastal sites around the nation. PBDEs are found in a variety of consumer products, from TVs and

Polybrominated diphenyl ethers or PBDEs, are a class of organobromine compounds that are used as flame retardants. Like other brominated flame retardants, PBDEs have been used in a wide array of products, including building materials, electronics, furnishings, motor vehicles, airplanes, plastics, polyurethane foams, and textiles.
PBDE flame retardants were commonly added to furniture, infant products, and electronics for many years. They have spread through the environment and break down slowly. U.S. production of some widely used PBDEs ended as of 2006, and the last major PBDE mixture is due to be phased out by the end of 2013.
