Toxic Dioxin — Environmental Health Leaders Blast EPA for Failing to Release Dioxin Health Report

20 Feb

Once Again American Public Denied Right to Know and Ability to Protect Families from Unnecessary Exposure

Advocates Urge EPA to Immediately Release Dioxin Health Report, Decry 27 Years of Delays Due to Chemical Industry Interference

(Falls Church, VA) For twenty seven years, the American public has been kept in the dark about the health impacts of dioxin.  Today environmental health advocates strongly condemned the US Environmental Protection Agency (EPA) for once again failing to meet their January 31st deadline to release their report on the noncancer impacts of dioxin.

“Shame on EPA Administrator Lisa Jackson for denying parents the information they need to protect their children from the health impacts of dioxin,” said Lois Marie Gibbs, Executive Director of the Center for Health, Environment & Justice (CHEJ).  “This is America — parents have the right to know.

Today the EPA has once again caved into pressure from Dow Chemical and their chemical industry cronies.  EPA shouldn’t cave in to chemical industry dollars and interests over public health.

Cancer, diabetes, infertility, learning disabilities and other chronic diseases linked to dioxin exposure are extremely costly to American taxpayers. EPA missed yet another deadline to release their report on dioxin, one of the most toxic chemicals on the planet.  In recent months, the chemical industry has been working behind closed doors to hide and distort the truth about the dangers of dioxin.

At the same time, Vietnam Veterans, breast cancer advocates, public health organizations, and environmental justice leaders have stood shoulder to shoulder and urged EPA to do what’s right for the health of American children and families.  We call on EPA Administrator Lisa Jackson to immediately release this important report.  We can’t wait any longer.”

EPA has been under intense pressure by environmental health, environmental justice, labor, health-impacted, and Vietnam Veterans organizations to release the non-cancer health assessment in recent weeks and ever since President Obama entered office.  Last week, a letter was delivered to EPA Administrator Jackson signed by over 2,000 organizations and individuals from across the country.

Over the past three weeks a broad coalition of organizations have written to EPA urging the agency to finalize this review The coalition includes Breast Cancer Fund, Endometriosis Association, Environmental Defense Fund, Greenpeace, International Brotherhood of Teamsters, Natural Resources Defense Council (NRDC), Sierra Club, Vietnam Veterans of America, Alaska Community Action on Toxics, Canadian Environmental Law Association, Center for Health, Environment & Justice, Clean Water Action, Ecology Center, Edison Wetlands Association, Environmental Working Group, Global Alliance for Incinerator Alternatives, Healthy Child Healthy World, Institute for Agriculture and Trade Policy, International POPS Elimination Network (IPEN), Ironbound Community Corporation, Kentucky Environmental Foundation, the Lone Tree Council, National Asian Pacific American Women’s Forum, Physicians for Social Responsibility, Reproductive Health Technologies Project, Science & Environmental Health Network, The Endocrine Disruption Exchange, Union of Concerned Scientists, Vietnam Agent Orange Relief & Responsibility Campaign, and Women’s Voices for the Earth.

In January, Rep. Ed Markey (D-MA), Ranking Member of the Natural Resources Committee and senior member of the Energy and Commerce Committee, sent EPA a letter urging the agency to finalize this dioxin assessment.  In April, Rep. Markey and 72 members of Congress sent a letter to EPA calling on the agency to release the report.

Dioxin is a known human carcinogen.  Dioxin also causes a wide range of adverse non-cancer effects including reproductive, developmental, immunological, and endocrine effects in both animals and humans. Animal studies show that dioxin exposure is associated with endometriosis, decreased fertility, inability to carry pregnancies to term, lowered testosterone levels, decreased sperm counts, birth defects, and learning disabilities.  In children, dioxin exposure has been associated with IQ deficits, delays in psychomotor and neurodevelopment, and altered behavior including hyperactivity. Studies in workers have found lowered testosterone levels, decreased testis size, and birth defects in offspring of Vietnam veterans exposed to Agent Orange.

Dioxin’s effects on the immune system of the developing organism appear to be among the most sensitive endpoints studied. Animal studies show decreased immune response and increased susceptibility to infectious disease. In human studies, dioxin was associated with immune system depression and alterations in immune status leading to increased infections.  Dioxin can also disrupt the normal function of hormones—chemical messengers that the boddy uses for growth and regulation. Dioxin interferes with thyroid levels in infants and adults, alters glucose tolerance, and has been linked to diabetes.

According to EPA, dioxin releases increased by 18% from 2009-2010 nationally.  Dioxin air releases increased by 10%.  The top ten U.S. companies that reported releasing dioxin into the environment in 2010 were Westlake Vinyls, Dow Chemical (Freeport Facility), Dow Chemical (Louisiana Operations), Missouri Chemical Works, Gerdau Ameristeel, Lehigh Southwest Cement, Formosa Plastics Corporation (Louisiana), Temple-Inland, Cahaba Pressure Treated Forest Products, and Clean Harbors Aragonite.  Four of these ten facilities make chemicals to produce polyvinyl chloride (PVC) plastic. Municipal waste incinerators, medical waste incinerators, landfill fires, and backyard burn barrels are some of the other top sources of dioxin in America.
