After 21 years, four Presidents, countless political battles and lots of pollution, the EPA finally released its health reassessment of Dioxin this past Friday. Like so many environmental decisions from this Administration, the report splits important hairs. While confirming that ultra-low exposures (we're talking 1 millionth of a gram or less) to Dioxin can cause damage to a person's immune and reproductive systems, cause skin rashes and liver damage, EPA says that levels of exposure for most Americans have declined so much over the last two decades that there should be no significant risk. To at least one expert, that was an      "very odd statement." Arnold Schecter of University of Texas School of Public Health, noted that EPA's assurances really didn't jibe "because some people are more highly exposed than average and some groups, such as fetuses and nursing babies, are more sensitive to the effects." What other populations are more highly exposed to Dioxin? People who live downwind of facilities where its emitted - power plants, cement plants, and lead smelters, to name a few. DFW residents live downwind from all three. Exide's lead smelter in Frisco was the 9th largest dioxin polluter in Texas in 2009, releasing more of the poison than industrial facilities many times its size. While most exposures come through eating or drinking animal products that contain dioxin because the animals themselves were contaminated and store it in their fat, breathing in dioxins directly is also a pathway of exposure when you live near a place that burns hazardous wastes, smelts metals, or deals with a lot of chlorinated materials. Like millions of DFW residents. While there was a lot of disappointment by environmentalists at the lack of follow-through on the report, the food industry is sweating bullets over its conclusions. Last year, food industry groups wrote the EPA, stating that  most Americans could “easily exceed the daily [0.7 picogram limit] after consuming a single meal or heavy snack." Now they're afraid safer food advocates will use the report to push for new restrictions on how much of one of the most poisonous substances ever discovered can be included in their food products. Indeed. How unreasonable to expect less human-made poison dreck in your food. No release date for the part of the reassessment dealing with cancer risks.
