Toxins found in fracking fluids and wastewater, study shows -- ScienceDaily

"In an analysis of more than 1,000 chemicals in fluids used in and created by hydraulic fracturing (fracking), researchers found that many of the substances have been linked to reproductive and developmental health problems, and the majority had undetermined toxicity due to insufficient information."
157 of them -- chemicals such as arsenic, benzene, cadmium, lead, formaldehyde, chlorine, and mercury -- were associated with either developmental or reproductive toxicity. Of these, 67 chemicals were of particular concern because they had an existing federal health-based standard or guideline, said the scientists, adding that data on whether levels of chemicals exceeded the guidelines were too limited to assess.
