In addition – because there’s always more to the fracking footprint – a triple whammy is formed in a chemical interaction between added chemicals and compounds found in the shale. As nasty to human health as it is complicated to pronounce, 4-nitroquinoline-1-oxide (4-NQO) is one of the most potent carcinogens known to man and while it is not a chemical additive nor a shale resident, it has been discovered in shale flowback fluids.
