The use of PFAS in fracking was refuted by Missi Currier, president of the New Mexico Oil and Gas Association in a column published in the Carlsbad Current-Argus on May 3.
PFAS exposure is prevalent among firefighters not only due to its use in emergencies but also because it is used in personal protective equipment. In support of these findings, states like Washington and Colorado have moved to restrict and penalize the use of Class B firefighting foam for firefighter training and testing.
The differences between additives for fracking in different countries are the type of chemicals used (hazardous, non-hazardous), the disclosure of chemicals and the composition of fracturing fluid. In 2010, Halliburton announced the creation of food additive based hydraulic fracturing fluid in response to calls for transparency and demand for a ...
Nonetheless, diverse methods are being tested including sonolysis, electrochemical oxidation, advanced oxidation processes, as well as the use of oxidative enzymes (such as peroxidase and laccase). [2] All of these methods promote the formation of hydroxyl radicals or other oxidizing agents that can oxidize PFAS and break its C−C bonds.
Long-chain PFAS chemicals perfluorooctane sulfonic acid, or PFOS, and perfluorooctanoic acid, or PFOA, are among the most studied of the nearly 15,000 types of PFAS used by industry.
The various recipes of fracking fluids had been shrouded in secrecy for years. Some say the ingredients are toxic, while others say they are completely safe. About the only thing we know for sure ...
Its use contributes to increasing the efficiency of the whole plant. [ 7 ] PFA is also used to make sampling equipment in analytical chemistry and for geochemical or environmental in situ studies in the field, when it is particularly important to avoid chemical contamination from metallic ions at trace levels.
One major way PFAS seep into food is when the chemicals are used in manufacturing, so it’s important that companies take steps to prevent PFAS from coming in contact with soil, water or outside air.
