  16. Persistent Bioaccumulative and Toxic (PBT) Compounds • PBT pollutants are chemicals that are toxic • persist in the environment and • bioaccumulate in food chains and, thus, • pose risks to human health and ecosystems

  17. alkyl-lead mercury and its compounds PAH - benzo(a)pyrene dioxins and furans mirex Chlordane aldrin/dieldrin DDT, DDD, DDE PCBs hexachlorobenzene toxaphene PBDE PFOS Persistent Bioaccumulative and Toxic (PBT) Compounds http://www.epa.gov/opptintr/pbt/cheminfo.htm
