UPDATE on PAHs…
“A citizen-requested study out of Oregon State University (OSU) and the University of Cincinnati has found that people living or working near active natural gas wells may be exposed to certain pollutants at higher levels than the EPA considers safe for lifetime exposure.
Kim Anderson, an environmental chemist with OSU, and her colleagues placed air samplers on the properties of 23 volunteers living or working at fracking sites right next to a gas well or up to three miles away.
The samplers, collected over a three-week period last February, picked up high levels of PAHs (polycyclic aromatic hydrocardons), including some that are linked with increased risk of cancer and respiratory ailments.Levels were highest closest to the wells and decreased by about 30 percent with distance.They were about 10 times higher than in a rural Michigan area with no natural gas wells.
Anderson and her team were able to discern whether the PAHs came from the Earth or from pyrogenic sources like the burning of fossil fuels. The team also accounted for the influences of wood smoke and vehicle exhaust, common sources of airborne pyrogenic PAHs.” http://www.laboratoryequipment.com/articles/2015/07/lowdown-fracking

Effects of Prenatal Exposure to Air Pollutants (Polycyclic Aromatic Hydrocarbons) on the Development of Brain White Matter, Cognition, and Behavior in Later Childhood
In finding a recent study proving that PAH’s (polycyclic aromatic hydrocarbons) are indeed associated with exposures that harm brain tissue in our pre and post natal youth, I found where Exxon compares d i e s e l (PAH) to be six times more than the threshold of worker exposures limits than if you were to you use Exxon’s recommended frac fluids …
Escaid™ PathFrac™ fluid,
FYI the government tried to tell the frackers not to use diesel, but they still do….we’ve so sadly found.)
A few years ago I visited one of our City of Arlington Gas Well inspectors and looked at the MSDS sheets for the drilling/operations phase and found BTEX items. Notice that Naphtha (a form of PAH’s) is present in the MSDS sheets in this video for the Chesapeake drill site by my home and the ATT Cowboys Stadium….
Also note at the very beginning of the video I read off the first MSDS number for petroleum crude oil to be #8002-05-9 a PAH …..
The MSDS sheets also included most of that infamous BTEX family… Toluene, Benzene, Ethylbenzene. It also had an MSDS sheet for…… *Hydrogen Sulfide!
Big note…those MSDS sheets in that video don’t even cover the hydraulic fracturing phase when the drillers hire out those companies like Schlumberger/Halliburton who have their own set of MSDS sheets.
Here are the hydraulic fracking chemicals used for my drill site courtesy of FracFocus (a fracking chemcial disclousure database)…
Note the petroleum distillates (PAH) and also notice the special secret sauces….
Note that FracFocus isn’t able to post the fracking ingredients until about two weeks after the frack.
*As usual I will post a letter on H2S (albeit it is from 2012) related to the topic of a PAH like diesel when burned can give off H2S…

Subject: Recent Inquiry
Attached you will find a Material Safety Data Sheet for the chemical to be
used a Hercules. It is called CC Eliminator. It works by reacting with any
hydrogen sulfide they may become airborne during the sludge removal
operations. It differs from a masking agent in that it reacts with and
removes the compound(H2S) rather than simply conceal the odor. A continuous
spray, or mist, of the CC Eliminator will be applied over the impounding
basin during removal operations.Thank you for your interest in this matter.(See attached file: DOC000.PDF)
