  2,3,7,8-TCDF (tetrafuran)

2,3,7,8-TCDF (tetrafuran) was not found in any of the samples above the limits of detection.

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).
