The MPCA uses a dioxin standard applicable to waters in the Lake Superior basin, and site-specific dioxin criteria elsewhere, to control the discharge of dioxin to surface waters. The standards or criteria can be the basis for permit effluent limits that must be met by dischargers in cases where dioxin is a concern, such as at a few ground water remediation sites. 2021-04-20 · Due to the high costs for laboratory analysis of dioxins, the number of samples collected for each study was limited and so caution is required when interpreting the findings. Nevertheless, these studies, completed in 2004, provide the largest survey of dioxin levels ever undertaken in Australia. About Dioxin: Its chemical name is 2,3,7,8-tetrachloro-dibenzo-para-dioxin, or TCDD. It is a persistent organic pollutant that contaminated Agent Orange and some of the other color-coded herbicides when the production of one of their components (2,4,5-T) was accelerated during wartime.[ii] TCDD is the most toxic of about 419 types of similar toxic compounds, which include PCBs (polychlorinated Medical Definition of dioxin. : any of several persistent toxic heterocyclic hydrocarbons that occur especially as by-products of various industrial processes (as pesticide manufacture and paper milling) and waste incineration especially : tcdd — see agent orange.

The Food and Drug Administration issues health advisories for dioxin in products for human consumption. Dioxin-like is a description used for compounds that have chemical structures, physico-chemical properties, and toxic responses similar to TCDD. Dioxin-like compounds (DLCs), including polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and dioxin-like polychlorinated biphenyls (PCBs) , ‘Arsenic and dioxin in the herbicides are expected to pose a health threat long into the future.’ ‘Some of the herbicide contained dioxin, one of the world's deadliest poisons.’ ‘But until two years ago, the pleasures of Zamami were spoiled by the presence of a garbage incinerator that spewed highly toxic dioxin into the atmosphere.’ ‘But dioxin and related toxic chemicals are detectable in the body years after exposure.’ ‘Cigarettes contain many pesticide residues, some chlorine chemicals that when burned produce dioxin, a known human carcinogen and cause of a host of diseases.’ 1.2 How are dioxins formed?

Over 70 chemicals, primarily the byproducts of combustion and other industrial processes, can be found in this family. Dioxin. Dioxin is a generic term given to two chlorinated ground structures, namely polychlorinated dibenzo-para-dioxins (PCDD) and polychlorinated dibenzofurans (PCDF) (commonly known as ‘dioxins’ or PCDD/Fs). Se hela listan på en.wikipedia.org Se hela listan på cdc.gov The toxicokinetic determinants of dioxin and related chemicals depend on three major properties: lipophilicity, metabolism, and binding to CYP1A2 in the liver. Lipophilicity increases with more chlorination and controls absorption and tissue partitioning. metabolism is the rate-limiting step for elimination.
