The term often used to refer to TCDD and/or any of the family of chemicals composed of 75 dioxin congeners and 135 furan congeners. TCDD is the abbreviation for 2,3,7,8 tetrachlorodibenzo-p-dioxin.
a general name for a large group of chemical compounds with similar structure. These compounds are made up of carbon, oxygen, hydrogen and chlorine atoms.
Dioxin is a naturally occurring compound and a by-product of environmental events such as volcanoes and forest fires. man-made processes such as manufacturing, paper and pulp bleaching, and exhaust emissions also yield dioxin. To find out more, go to the Chlorine Chemistry Council.
A carcinogenic contaminant generated when chlorine is used in bleaching woodpulp.
Dioxin is the collective name for certain organic chlorine compounds. There are 210 of them, some of which are highly toxic.
very toxic chemical compound resulting from the combustion of organic matter. There are 210 types of dioxin, 17 of which are considered harmful.
The most toxic organochlorine, dioxins are the unavoidable, unwanted by-product of industrial processes which involve the use of chlorine (including the manufacture of pulp, some plastics and many pesticides) and the burning of chlorine-contaminated wastes. A known carcinogen, dioxin is now implicated in numerous developmental, immunological and reproductive failures in humans and wildlife.
A synthetic organic chemical of the chlorinated hydrocarbon class. It is one of the most toxic compounds known to humans, having many harmful effects, including induction of cancer and birth defects, even in extremely minute concentrations. It has become a widespread environmental pollutant because of the use of certain herbicides that contain dioxin as a contaminant.
Typically defined as a class of similar chorinated compounds that are persistent, bioaccumulative, and very toxic. Predominantly related to human activities - manufacturing and incineration.
highly toxic chemical byproduct of combustion & certain chemical & industrial processess involving chlorine
any of several toxic or carcinogenic hydrocarbons that occur as impurities in herbicides
2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD). The most highly toxic of a group of structurally similar polychlorinated aromatic hydrocarbons, differing in the number and location of chlorine atoms in their molecular structure, often collectively referred to as dioxins. Dioxins are produced as a byproduct of industrial processes such as the manufacture of certain herbicides, manufacture of paper, and high-temperature processes such as incineration; some of the less toxic dioxins are produced in small amounts in natural combustion. Dioxins have a strong tendency to bioaccumulate. Dioxins are quite stable, and therefore persist in the environment for long periods of time. 2,3,7,8-TCDD is classified by USEPA as a known human carcinogen.
Refers to a group of chemical compounds from three closely-related families: dibenzo-p-dioxins (CDDs), chlorinated dibenzofurans (CDFs) and polychlorinated biphenyls (PCBs). One of the most well known (and most toxic) forms of dioxin is 2,3,7,8-tetrachlorodibenzo-p-dioxin, or TCDD. Dioxins are formed as a by-product of combustion processes such as waste incineration and burning fuel. Studies show that short-term exposure to high levels of dioxins may result in skin and altered liver function. Long-term exposure is linked to impairment of the immune system, the developing nervous system, the endocrine system and reproductive functions. The International Agency for Research on Cancer (IARC) categorises dioxin as a "known human carcinogen".
a group of chemical compounds that share certain characteristics. Dioxins are formed as a result of combustion processes such as waste incineration and burning fuels such as wood and coal.
A class of chemical compounds containing carbon, hydrogen, oxygen and chlorine, part of a larger group called polycyclic halogenated aromatics. Dioxins are human-made by-products of industrial processes such as incineration, paper milling, pesticide manufacture, and smelting. One dioxin, TCDD, is the most toxic synthetic substance known.
Chlorinated organic compounds with low water solubility that bind to sediment and soil particles and concentrate in fatty tissues. Dioxin bioaccumulate moderately in the aquatic environment. They are by-products of incomplete combustion in the presence of chlorine and are found in fly ash and other products of these processes.
A toxic component of Agent Orange, among other substances.
Short for 2,3,7,8-tetrachlorodibenzo-para-dioxin, also TCDD. Dioxin is formed as an unintentional by-product of many industrial processes involving chlorine such as waste incineration, chemical and pesticide manufacturing and pulp and paper bleaching. The major sources of dioxin are in our diet. Since dioxin is fat-soluble, it accumulates in the food chain and it is mainly found in meat and dairy products. In fish alone, the toxins accumulate so that dioxin levels in fish are 100,000 times that of the surrounding environment.
A group of chlorinated organic chemicals formed in very small quantities in most combustion processes and as accidental byproducts of the manufacture of certain herbicides, bactericides, wood preservatives, and other products. Of the 210 dioxins, about a dozen are considered highly toxic, causing skin disorders, cancer and genetic disorders.
A special group of dangerous chemicals known as persistent organic pollutants. Once dioxins have entered the environment or body, they are there to stay due to their uncanny ability to dissolve in fats and to their rock-solid chemical stability. They are formed as an unintentional by-product of many industrial processes involving chlorine, such as waste incineration, chemical and pesticide manufacturing and pulp and paper bleaching, but can also result from natural processes, such as volcanic eruptions and forest fires.
a toxic chemical found in some paper products, pesticide-treated food, any many other chemical by-products. It is now wide-spread throughout the world and may be linked to endometriosis because of the Xenoestrogenic effect on the body. See Xenoestrogens below.

Unwanted chemical byproducts of incineration and some industrial processes that use chlorine. Dioxins can accumulate in fish and wildlife and are suspected human carcinogens. A critical pollutant considered to be highly toxic, 2,3,7,8 tetrachlorodibenzo-p-dioxin, or TCDD, is a variant in a family of 75 chlorinated organic compounds referred to as dioxins. An unwanted chemical byproduct of incineration and some industrial processes that use chlorine, dioxin tends to accumulate in the fatty tissue of fish. Dioxin is a suspected human carcinogen.
a carcinogenous compound produced, among other ways, during trash incineration.
A group of 75 chlorinated compounds. Dioxins are formed in a complex process, where chlorine combines with other additives during bleaching.
a highly toxic contaminant; sometimes used in chemical warfare, specifically Agent Orange
any of a family of compounds known chemically as dibenzo-p-dioxins. Dioxins are sometimes generated by industrial processes, and can contaminate water and soil. Tests on laboratory animals indicate that it is one of the most toxic man-made chemicals known.
Chlorinated organic compound: a by-product of the paper-making process that uses chlorine as a bleaching agent. Dioxins can be released into the atmosphere through the incineration of chlorinated paper. They are believed to be highly toxic to humans
One of the most hazardous of all chemicals, can cause both acute and long-term effects ranging from chloracne, a skin disease, to cancer, reproductive failures, and reduced resistance to infectious disease.
is a group of highly toxic organic compounds that are often found in herbicides. RCRA regulations require a higher destruction and removal efficiency (99.9999) for dioxins than the DRE required for most other organic compounds (99.99).
One of the most toxic man-made compounds known and like the PCBs and dibenzofurans that they are related to, they are persistent contaminants in the environment. Collectively, these groups of compounds belong to a class of compounds called polychlorinated diaromatic hydrocarbons (PCDH). Health hazards to humans and animals from PCDHs include a variety of species and tissue specific effects, such as tumor promotion, birth defects, hepatotoxicity, immunotoxicity, dermal toxicity, alterations in endocrine homeostasis, and induction of numerous enzymes.
Dioksiini Dioxin Supertoxic polychlorinated dibenzo-p-dioxines and dibenzonfurans, more than 200 compounds.
Common name for polychlorinated dibenzo--dioxins and polychlorinated dibenzofurans (PCDD/PCDF).
A carcinogenic by-product of many manufacturing processes, especially the weed-killers 245-T and 24-D and the manufacturing of pulp for paper production. It is also found as a by-product in the manufacture of foaming cleansers such as shampoos, toothpastes and cleansers. Dioxin contaminated containers which include some plastic manufacturing processes for plastic bottles sometimes transfer dioxins into the product itself. It has been shown that dioxin is up to 500,000 times more carcinogenic than DDT. Dioxin is one of the most potent and powerful poisons known to man
a man-made chemical by-product formed during the manufacturing of other chemicals and during incineration. Studies show that dioxin is the most potent animal carcinogen ever tested, as well as the cause of severe weight loss, liver problems, kidney problems, birth defects, and death.
Toxic chemical by-products of incineration and some industrial processes that use chlorine.
A chemical by-product formed when compounds containing chlorine are used during the bleaching stage of pulp manufacturing.
Toxic chemical compounds (the best known is the so-called Seveso poison) that result as undesired by-products of certain technical processes; they are extremely water-insoluble, volatilise very slowly and largely penetrate into the environment bound to dust and soil particles; can cause cancer.
Any of a family of compounds known chemically as dibenzo-p-dioxins. Concern about them arises from their potential toxicity as contaminants in commercial products. Tests on laboratory animals indicate that it is one of the more toxic anthropogenic (man-made) compounds.
Dioxin is the popular name for the family of halogenated organic compounds, the most common consisting of polychlorinated dibenzofurans (PCDFs) and polychlorinated dibenzodioxins (PCDDs). PCDD/Fs have been shown to bioaccumulate in humans and wildlife due to their lipophilic properties. Recently, polybrominated dibenzofurans and dibenzodioxins have been discovered as impurities in brominated flame retardants, such as polybrominated diphenyl ethers.
