WASHINGTON — The U.S. Environmental Protection Agency (EPA)
announced that it plans to complete the non-cancer portion of its Reanalysis of Key Issues Related to Dioxin
Toxicity and Response to NAS Comments, and post the final non-cancer
assessment to the Integrated Risk Information System (IRIS) by the end of
January 2012, according to a press
After completing the non-cancer portion, EPA will finalize
the cancer portion of the dioxin reanalysis as quickly as possible.
Dioxins are toxic chemicals that share a similar chemical
structure and act through a similar mechanism.
dioxin levels in the environment have been declining since the early 1970s,
dioxins remain a concern because they will continue to enter the food chain
through releases from soils and sediments, and they have been the subject of a
number of federal and state regulations and cleanup actions.
