Seattle Recognizes PBTs as Toxins

has become the first city in the nation to officially recognize a threat to public and environmental health posed by persistent, bioaccumulative, toxic chemicals (PBTs), including dioxins, mercury, and polychlorinated biphenyls (PCBs). The city is currently developing criteria for its own departments, offices, and agencies requiring that PBT levels be taken into account in addition to other environmental, social, and economic factors in all city purchasing decisions.
