Since then, a number of government-led guidelines have been announced to regulate these environmental pollutants and safeguard against potential harm due to human exposure. The European Chemicals Agency (ECHA) led with their universal PFAS restriction proposal covering a wide-range of commercial ...

Submitters who do not know the underlying identity of the chemical other than a generic chemical name (i.e., do not know a CASRN, or TSCA Accession or LVE numbers) are not required to assert and substantiate a CBI claim for chemical identity. Reporters using the article importer form ...
an interesting pattern emerges. The results demonstrate that within the European Union, France, Italy, Germany, the Netherlands, Denmark, Sweden, and Norway exhibit a significant number of samples exceeding the LOQ for PFAS contamination. This observation is consistent with prior studies examining conta...
and yet there are thousands of various PFAS compounds with different CAS (Chemical Abstracts Service) Registry Numbers. There are now over 4,700 CAS registered PFAS compounds being used in products and industries. Furthermore, there is also debate regarding the risk of PFASs to human health, su...

The external network also clusters in-source fragments and neutral losses, preventing duplicate annotations for the same PFAS. The spectra of Node 36 were the same as those of Node 181 (n:2:3 FTECAs, Fig.3b). The retention times of all the homologs of these two classes were within 0.05...

The research suggests that exposure to high levels of PFAS may [list of health effects]. PFOA and PFOS are also very persistent in the human body, and exposures to these chemicals are known to have a number of adverse effects in labo- ratory animals and humans. As a result, as people ...
