This noxious mixture spewed out by incinerators includes about 200 compounds known as polychlorinated dibenzodioxins and polychlorinated dibenzofurans, many of which are toxic and some of which are potentially cancer-causing.
Polychlorinated dibenzodioxins (PGDDs), poly-chlorinated dibenzofurans (PCDFs), and polychlorinated biphenyls (PCBs) are unintended by-products of certain chemical processes involving chlorine and incineration processes.
Polychlorinated dibenzodioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are unintended by-products of certain chemical processes involving chlorine and incineration processes [Agency for Toxic Substances and Disease Registry (ATSDR) 1994, 1998].
We developed consumption levels based on the tolerable daily intake (TDI) of the World Health Organization (WHO 1998), which assesses dioxin health risks via a toxicity equivalency (TEQ) approach that characterizes dioxins and DLCs as 17 2,3,7,8-substituted polychlorinated dibenzodioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs), and the 12 non-ortho and mono-ortho PCBs.
Polychlorinated dibenzodioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and polychlorinated biphenyls (PCBs) constitute a group of polyhalogenated aromatic hydrocarbons that are persistent, widespread environmental contaminants, frequently detected at parts-per-trillion levels (lipid basis) in animals and humans throughout the industrialized world (Zook and Rappe 1994).
The chapters on sources and human exposure emphasize that "dioxins" encompasses 210 different polychlorinated dibenzodioxins and dibenzofurans emitted in varying amounts from numerous sources.
