Arsenic, benzene, formaldehyde, lead and mercury are among more than 200 toxins found in fracking fluids and wastewater that may pose serious risks to reproductive and developmental health, according to a paper published on Wednesday.
And that list may just be just the tip of the iceberg, said Nicole Deziel, an environmental health expert at the Yale School of Public Health and senior author of the new study.
Many more chemicals known to be used in fracking could pose similar risks, yet remain unstudied, Deziel said. Other substances involved in oil and natural gas production remain undisclosed by fracking companies.
