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. TheEuropean Chemicals Agency(ECHA) led with theiruniversal PFAS restriction proposalcovering a wide-range of commercial products conta...
Additionally, three PFAS chemicals are currently under review by the Office of Environmental Hazard Assessment (OEHHA) for possible addition to the Proposition 65 substance list: Perfluorodecanoic acid (PFDA) Perfluorohexanesulphonic acid (PFHxS) Perfluoroundecanoic acid (PFUnDA) Businesses that expose th...
While many reporting requirements provide a list of specific PFAS chemicals, such as the Toxics Release Inventory (TRI), TSCA Section 8(a)(7) goes with a structural condition. This means that any chemical that satisfies any of these three conditions must be reported, regardless of its inclusion...

As noted above, the DEP has proposed revisions to the RAGs which would significantly lower the RAG thresholds and expand the number of PFAS chemicals subject to RAGs. 5. Maine FoodstuffsAction Levels PFOS Milk210 ppt Beef3.4 ng/g 6. Maine Crop-Specific Soil Screening Levels for Dairy FarmsAct...
contractor report (such as the CAS Registry, PubChem, TSCA Chemical Substances Inventory, and European Inventory of Existing Commercial Chemical Substances) “may increase or decrease the total number of PFAS chemicals and subsets of PFAS used in consumer products or with other defined characteristics...
This paper describes a database framework that enables one to rapidly explore systematics in structure-function relationships associated with new and emerging PFAS chemistries. The data framework maps high dimensional information associated with the SMIL
among others. One of the concerning characteristics of PFAS is their persistence and bioaccumulative nature. These chemicals do not readily degrade in the environment, leading to their long-lasting presence, and they can accumulate in the food chain. The persistence of PFAS means that they do not...
