dioxin | englesko - srpski prevod



Any of several toxic or carcinogenic hydrocarbons that occur as impurities in herbicides.
Any of a family of over 200 organic chemicals, all of which are heterocyclic hydrocarbons (see cyclic compounds).
The term is commonly applied, however, to only one member of the family, 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD), a highly toxic chemical that occurs, for example, as an impurity in the defoliant Agent Orange, used in the Vietnam War, and sometimes in the weedkiller 2,4,5-T. It has been associated with a disfiguring skin complaint (chloracne), birth defects, miscarriages, and cancer.
Disasters involving accidental release of large amounts of dioxin into the environment have occurred at Seveso, Italy, and Times Beach, Missouri, US. Small amounts of dioxins are released by the burning of a wide range of chlorinated materials (treated wood, exhaust fumes from fuels treated with chlorinated additives, and plastics) and as a side-effect of some techniques of paper-making. The possibility of food becoming contaminated by dioxins in the environment has led the EC to significantly decrease the allowed levels of dioxin emissions from incinerators. Dioxin may be produced as a by-product in the manufacture of the bactericide hexachlorophene.
