Total Chlorinated dioxins & furans

Chlorinated dioxins are unwanted byproducts of the manufacture and burning of products that contain chlorine. Dioxins cause cancer in humans, and they are generally considered to be among the most toxic environmental contaminants known to man. As a class, dioxins are extremely toxic, persistent, bioaccumulative, and lipophilic ("fat-loving"). This means that dioxins build up and are stored in fatty tissues and fluids, such as breast milk, and can be passed on to fetuses and infants during pregnancy and lactation. Most people are exposed to dioxin through the food they eat, primarily from meat, dairy, fish and eggs.

In humans, dioxins are associated with cancer, skin lesions, damage to the nervous system and immune system, altered carbohydrate and lipid metabolism, thyroid disruption, altered menstrual cycling, and cardiovascular effects.

In laboratory animals, dioxins are known to cause a variety of effects including cancer and impaired reproductive, endocrine, cardiovascular, immune, respiratory, neurological and metabolic function. In addition, dioxins cause skin disease and birth defects.

In dioxin family of chemicals - pollutants from PVC production, industrial bleaching, incineration; cause cancer, may harm hormone system.

5pg/g lipids in blood serum125


Chlorinated furans, also called chlorinated dibenzofurans or CDFs, are toxic, persistent, bioaccumulative, and lipophilic ("fat-loving""). This means that CDFs build up and are stored in fatty tissues and fluid, such as breast milk, and can be passed on to fetuses and infants during pregnancy and lactation.

In humans, CDFs are associated with premature birth and abnormal development, liver toxicity, skin disease, eye inflammation, and damage to the nervous, immune, endocrine, and reproductive systems (ATSDR 1994b).

In laboratory animals, CDFs are known to cause a variety of effects including damage to the reproductive, endocrine, immune, and nervous systems. In addition, CDFs harm the kidneys and gastrointestinal tract, and cause birth defects (ATSDR 1994b).

polybrominated diphenyl ethers (pbdes)

30-35 of 46 found

Fire retardants in furniture foam, computers, and televisions. Accumulate in human tissues. May harm brain development.

1.11ng/g lipids in blood serum314


Total Polybrominated diphenyl ethers (PBDEs)

Brominated fire retardants currently used in plastics and fabric. The major use is in electronic devices; the minor use is as a backcoating on industrial fabrics. Are directly toxic to mammals and breakdown to more dangerous forms in the environment.

A fire retardant used in TVs, monitors and electronics. Growing evidence that chemical breaks down in the environment to more persistent and toxic forms.
