TheSuperfund lawthen designated PFOA and PFOS as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), coinciding with a few regional regulations updates: such as theEuropean Union(EU) and the state ofNew York banning PFASin food packaging, and...

The most-studied types of PFAS — PFOA and PFOS — cannot exceed 4 parts per trillion in public drinking water. FNA and PFHxS (older versions of PFAS) and GenX chemicals (created to replace PFOA) are restricted to 10 parts per trillion. These are the lowest limits that labs can detect a...
The extraction method standardized for soil and sludge should be suitable for different types of waste and products, however this will require testing. Although the Regulation (EU) 2019/1021 (EU POP regulation) has set limit values for PFOA and related compounds in waste there is, however, no...
Interestingly, only the oat β-glucan group saw significant reductions in the NASEM PFAS concentration, which appeared to have been driven by combined reductions in PFOA and PFOS. It is not necessarily surprising that differences in effect across PFAS types are seen, given that the ratio of ...
Since the cell assemblies of rice husk consist of 20% silica, and the cellulose and lignin serve as the carbon precursor template, the fabrication of HPC from rice husk involves the removal of silica between the cells followed by steam activation to create different porous structures. The ...
indicating their potential commercial use. The structures of PFTeECAs and PFPeECAs are similar to Gen-X, which has been widely used as a PFOA alternative and detected around the world49. These classes may have same usage as Gen-X. In addition, n:4 FTCAs, n:2 FTECAs, and 7:3 FTECA...
's work,47 water-dispersible hybrid capsules, which were prepared from oil-in-water emulsions stabilized by GO and an outer layer of amino-functionalized mesoporous silicate, were used to adsorb PFOA from water. They reported an adsorption capacity of >60 mg g−1 dependent on pH and PFOA ...
