    Industrial, agricultural and other anthropogenic activities have lead to the introduction of thousands of pollutants, most of them synthetic organic compounds to the marine environment (Dachs and Méjanelle ). A fraction of these organic compounds, called persistent organic pollutants (POPs), are chemicals that have become a major concern because of their toxicity, persistence DF - Dioxins and Furans. Looking for abbreviations of DF? It is Dioxins and Furans. Dioxins and Furans listed as DF. Dioxins and Furans - How is Dioxins and Furans abbreviated? are toxic chlorinated compounds that are usually released as mixtures into the environment. Polychlorinated biphenyls (PCB), polychlorinated dibenzo-p-dioxins +and+Furans.

      Dioxins and furans are two very similar groups of polyhalogenated compounds that are well-known toxic and persistent pollutants. Often the term "dioxins" refers to both dioxins and furans. The most well-studied compound is 2,3,7,8-tetrachlorodibenzo-p-dioxin or TCDD. Dioxin is formed as a by-product of many industrial processes that involve chlorine including waste incineration, chemical and ?title=Dioxin. Levels and trends in abiotic environments, biota, and human exposure via food, as well as the risks to the environment and humans from polychlorinated dibenzo dioxins, furans, and PCBs are also discussed.

People may be exposed to background levels (i.e., low concentrations) of DLCs by breathing air, by consuming food or beverages, or by their skin coming into contact with DLC-contaminated materials (ATSDR, ). Inspotted sandpipers (Actitis macularia) were studied on the Hudson River near Fort Edward south to New Baltimore, NY and on two river drainages that flow into the Hudson River.
