Dioxin is the name given to a group of persistent, very toxic chemicals. The group includes chlorinated dibenzofurans, and dibenzo-dioxins, the most toxic of which is 2,3,7,8 -tetrachlorodibenzo-p-dioxin (TCDD). The group also includes related compounds which are structurally similar and are dioxin-like in their activity. The toxicity of these compounds is measured against TCDD using “toxic equ...
متن کاملOccurrence, Fate and Treatment Methods of Polycyclic Aromatic Hydrocarbons, Polychlorinated Biphenyls, Dioxins and Furans: A Mini Review
Polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), dioxins and furans are persistent organic pollutants with well-known toxicity and carcinogenic activity. These organic pollutants have the tendency to bioaccumulate, present little or no biodegradation and subsequently, could cause a menace to the ecosystems and human health. This review discusses the occurrence, fate an...

Human milk Body burden Polychlorinated dibenzo-p-dioxins and dibenzofurans Dioxin-like polychlorinated biphenyls Risk assessment Public health ABSTRACT: A study on polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and dioxin-like polychlorinated biphenyls (dl-PCBs) was conducted in a pooled sample of breast milk from 27 first-time mothers (primiparous) living in t...
متن کاملChanging sources of polychlorinated dibenzo-p-dioxins and furans in sediments and ecological risk for nekton in the lower Passaic River and Newark Bay, New Jersey, USA.
Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) were measured in sediments (surface and deeper sediments) and porewater of the lower Passaic River and Newark Bay (New Jersey, USA) to apportion their sources and conduct an ecological risk assessment. Positive matrix factorization was applied to identify sources of PCDD/Fs. Five source profiles were extracted from the positive matri...
متن کاملDioxins and furans: epidemiologic assessment of cancer risks and other human health effects.
Within the last two decades tremendous efforts have been made to uncover the potential risks to human health associated with exposure to polychlorinated dibenzop-dioxins and polychlorinated dibenzofurans (PCDD/PCDF), especially for the general population exposed at background levels. Very few other chemicals have been investigated as intensively as these substances, in particular, the most toxi...
