Chemicals used for fracking worse for human health than known

Researchers have released findings that fracking chemicals may have a worse impact on human health than previously known.

The results that were presented at the joint meeting of the International Society of Endocrinology and the Endocrine Society: ICE/ENDO 2014 in Chicago reveal chemicals used in hydraulic fracturing not only disrupt hormones of reproduction, but they also block the activity of thyroid and glucocorticoid hormone receptors.

Fracking has become a subject of controversy because the chemicals used are known toxins and carcinogens. Over 600 chemicals are used in the process.

There is also widespread concern about drilling for gas because it disrupts the environment and can spew toxins into our waterways and water supplies. Drilling for natural gas is also believed to contribute to air pollution and it devastates landscapes.

Birth defects, cancer and more linked to fracking chemicals

The newest study found fracking chemicals tested have a more negative effect on health than what was already known.

Christopher Kassotis, a PhD student at the University of Missouri, Columbia. said in a press release: "The high levels of hormone disruption by endocrine-disrupting chemicals (EDCs) that we measured, have been associated with many poor health outcomes, such as infertility, cancer and birth defects."

Kassotis and his team tested 24 chemicals that are injected into the earth under high pressure during fracking, finding that all of those used most often block the previously mentioned hormone receptors in the body.

Spills that occur when chemicals and millions of gallons of water are injected underground can contaminate ground and surface water Kassotis said.


EDCs that disrupt the hormones estrogen and androgen - a precursor to testosterone - were found in moderate to high amounts in Garfield County, Colorado from documented spills in earlier studies.

Makes one think that fracking may be contributing to the rise in cases of thyroid problems, including thyroid cancer.
I think that's fluoride in our water.
Good point!
Deborah, you read my mind.
