Polychlorinated dibenzofurans (PCDFs)

Polychlorinated dibenzofurans (PCDFs) are commonly found in the emissions of trash-burning incinerators. They form in the cooler sections of the incinerator, and controlling combustion conditions does not reduce their emissions. PCDFs were never intentionally manufactured and have no practical use.

Aside from occupational or accidental exposures, most human exposure to PCDD/PCDF results from dietary intake, primarily through consuming meat, milk, eggs, fish, and related products. PCDFs are persistent in the environment and accumulate in animal fat.

Exposure to PCDFs has been associated with cancer.
