Study Finds Persistent PCB Contamination Linked to Infertility
Back in 1979, the U.S. government banned Polychlorinated Biphenyls [PCBs] after adverse health effects, including cancer, heart disease, and adrenal and thyroid problems, were linked to the chemical compound. Three-and-a-half decades later it turns out that PCBs are even worse than scientists initially thought, lingering in air, water, and soil and continuing to pollute the environment.
Since PCBs don't degrade naturally, scientists have concluded that they can persist for decades and accumulate in human and animal tissue. Worse, the Longitudinal Investigation of Fertility and the Environment, a four-year survey conducted by the National Institutes for Health -- study results were published in Environmental Health Perspectives in late 2012 -- has conclusively tied them to infertility.
Dr. Peter deFur is an environmental consultant and president of Environmental Stewardship Concepts LLC, a Richmond, Virginia company that assists community groups, government agencies, and businesses with environmental clean-up. He notes that, "every state has a PCB contamination problem from a river, an old Superfund site, or buildings that were constructed before the PCB ban went into effect. Most of us carry some body burden of these chemicals, substances that we now know impact pregnancy as well as the brain growth and development of fetuses and children."
