There are now hundreds of peer reviewed scientific articles on all aspects of toxins related to unconventional oil and gas production.
The Endocrine Disruption Exchange (TEDX) has published research and aggregated data identifying low-dose exposure to chemicals associated with oil and gas development and operations as Endocrine Disrupting Chemicals (EDC). These chemicals affect not only reproduction and fetal development, but are linked to respiratory health, metabolism issues, malignancy as well as all the problems listed below.
The New York State Department of Health (NYSDOH) released A Public Health Review Of High Volume Hydraulic Fracturing For Shale Gas Development in December 2014.
In this study, it found that residents living near fracking activities had the following health problems: skin rash, nausea or vomiting, abdominal pain, breathing difficulties, cough, nosebleed, anxiety, stress, headache, dizziness, and eye and throat irritation. This study led to their recommendation that fracking should be banned in New York State.
