Humans may be harmed by endocrine disrupting chemicals released during natural gas mining
Scientists recommend process to examine total endocrine disrupting activity from exposure to harmful mixtures

COLUMBIA, Mo. – More than 15 million Americans live within one mile of unconventional oil and gas (UOG) operations that combine directional drilling and hydraulic fracturing, or “fracking,” to release natural gas from underground rock. Scientific studies still are inconclusive on the potential long-term effects on human development. Now, Susan C. Nagel and Christopher D. Kassotis, researchers with the University of Missouri, and national colleagues have conducted a review of research on health effects associated with UOG operations and concluded these activities have potential for environmental release of a complex mixture of endocrine disrupting chemicals (EDCs) that could potentially harm human development and reproduction.

The authors reviewed more than 100 scientific, peer-reviewed publications and examined the studies thoroughly for patterns and links that focused on UOG chemicals and human development. In their peer-reviewed commentary, the authors concluded that available research suggests potential adverse health outcomes and note a dearth of evidence-based research related to the UOG process.

Additionally, there is strong evidence of endocrine disrupting chemical mixtures having additive effects, so this approach also may be more sensitive.”

Nagel, an associate professor of obstetrics, gynecology and women’s health in the School of Medicine, and an adjunct associate professor of biological sciences in the College of Arts and Science at MU, conducted the review with fellow MU researchers Chris Kassotis, a recent doctoral graduate in the Division of Biological Sciences in the College of Arts and Science, and Jane McElroy, an associate professor in family and community medicine in the School of Medicine. Don Tillitt, an adjunct professor of biological sciences and a research toxicologist with the U.S. Geological Survey, also contributed to the study.

Endocrine Disrupting Chemicals and Oil and Natural Gas Operations: Potential Environmental Contamination and Recommendations to Assess Complex Environmental Mixtures (37 pages)

Excerpt from pages 7-8:

EDC Activity in Water Near Oil and Natural Gas Operations. We have assessed the estrogen and androgen receptor activities of water samples collected from five sites in a drilling-dense region of Garfield County, Colorado that had experienced industry related spills or preventable discharges relative to surface and ground water collected immediately outside of the drilling-dense region (Kassotis et al. 2014). Analysis of these samples revealed that surface and ground water from Garfield County spill sites contained significantly elevated estrogen agonist, estrogen antagonist, and androgen antagonist activities relative to reference sites (Kassotis et al. 2014). Independent analytical water testing at these sites identified chemicals that others or we have shown to exhibit these same agonist and antagonist activities (discussed in Kassotis et al. 2014).

    Do we need another peer reviewed study to tell those responsible that they are poisoning us with there activities. They care nothing for those being exposed only the profits they make!!

    First of all this is a review of more than 100 scientific studies. It is not a study per se.

    I am not a scientist and I am not a researcher but I do know we have to prove causation. Meaning we have to provide scientific proof that the chemicals used in UOG operations cause serious health problems and birth defects. Last year Dr. Nagel identified EDCs in fracking chemicals.

    Now the researchers are saying that based 10 years of studies plus air quality and water quality samples near UOG operations, EDCs exist in the environment. We have absolute proof. This review takes all the studies and research to the next level and prescribes not more studies but human and animal HEALTH ASSESSMENTS that analyze the effects of these endocrine disrupting chemicals from UOG operations, using genetics and biochemistry.

    When you understand science you understand that this is the only path to proving causation.

    As a risk management professional for many years his has been my recommendation:

    A Health Impact Assessment would: Indentify potential effects of gas and oil development on the health of the people and describe what effects it will have on its citizens. Minimal increases in incidences of chronic health problems could impact thousands of people and create escalating health care costs. Solicit and perform independent studies from many disciplines in the evaluation of complex hazards and exposures created by gas & oil development. Provide emphasis on segments of the population most vulnerable. Specifically infants, children, pregnant women and the elderly. Consider health risks from cumulative impacts on gas and oil development including radon exposure in homes, exposure to carcinogenic chemicals and the exposure from toxic contaminants from drilling, fracking, and transportation. Examine occupational risks to workers and those living on or near drilling, fracking, and completed well sites. Recommend and implement actions to minimize or eliminate health effects to protect people that the assessment indentifies.

    I ask you to support human kind in protecting their health from a rogue industry in search of profits at any cost to their shareholders with little or no concern to those who choose to call Colorado their home by performing risk assessments and analysis, health impact assessments including cost benefit analysis, environmental impact assessments including water, soil & air impacts evaluations, and real-estate value assessments including market, financial, return on investment scenarios before you allow the granting of permits to further develop the industry’s mineral resources.

    Amazing isn’t it? They require an EIS (environmental impact study) before drilling but no HIA (health impact assessment).

  5. frackfiles Says:

    Not surprising if you have something you don’t want known about public health impacts.

  6. Peggy Tibbetts Says:

    Their version of risk management.
