Previous studies have shown that EDCs disrupt normal sex-hormone function in humans.

A new study has found high levels of chemicals known as endocrine-disrupting chemicals (EDCs) in water samples obtained at sites in the state of Colorado where hydraulic fracturing (fracking) is used to extract oil and gas. Previous studies have shown that EDCs disrupt normal sex-hormone function in humans.
