Their research found that 75% of the chemicals could affect the skin, eyes,and other sensory organs, and the respiratory and gastrointestinal systems. Approximately 40–50% could affect the brain/nervous system, immune and cardiovascular systems, and the kidneys; 37% could affect the endocrine system; and 25 killing a loved one via cancer, you would need a little more legal ammunition than "it just makes common sense" against an army of corporate lawyers.
2011 article in the journal, Human and Ecological Risk Assessment, examined the potential health impacts of oil and exemptions) identified from drilling operations throughout the U.S.
Although the Centers for Disease Control and Prevention (CDC) has yet to investigate the potential impacts of fracking, the director of CDC's National Center for Environmental Health and the agency for Toxic Substances and Disease Registry, Christopher J. Portier, PhD, has called for health studies to be published.

A 2012 paper was published in the journal, Environmental Health Perspectives, examining the composition of state and federal advisory committees tasked to consider the potential environmental and health effects of fracking in the Marcellus shale region. The researchers found that there was not one health expert among the 52 people comprising
Health impacts from fracking are only % could cause cancer and mutations. the greater your health risk. Sounds obvious, but if you were to sue an oil company for the suspected now being examined by health experts, since such large-scale drilling is a recent phenomenon. Exposure to toxic chemicals even at low levels can cause tremendous harm to humans; the endocrine system is sensitive to chemical exposures measuring in parts-per-billions, or less. Nevertheless,
