PFAS are a broad group of chemicals with numerous different properties and applications. Chemicals within the group arecategorized by their chemical and physical properties, but calling them all PFAS has caused confusion in the scientific community and for the general public. For example, stating that...
Overview of PFAS Due to their superior oil, water, and heat resistance, PFAS are used in a wide variety of products, ranging from industrial products to household goods. Different organizations define PFAS in different ways, but OECD (2021) defines them as follows, a definition that includes...

Water providers will have three years to test for PFAS. They’ll also need to tell the public if results are too high. Article content And if results are a concern, utilities have two more years to install treatment. The EPA estimates that 6% to 10% of water systems will have leve...
PFAS were found in the majority of the straws tested and were most common in those made from paper and bamboo. They were not found only in steel straws tested. PFAS are used to make everyday products, from outdoor clothing to non-stick pans, resistant (抵抗 to water, heat and stains....
This indicates many reported toxic effects of PFAS are, theoretically, unlikely to occur outside the laboratory. However, lack of information on new PFAS as well as their precursors and degradation products, coupled with lack of knowledge of their mixture toxicity means our understanding of the ...
Forever chemicals are present in a huge variety of industrial and consumer products. Although some compounds have been phased out, these products still exist — and when we use or dispose of them, they can add PFAS to the environment. This includes both surface water and groundwater, which ar...
So, what are these PFAS everyone keeps talking about? Perfuoroalky substances (known as PFAS) are chemicals that are used to help make substances water and grease proof, which is why most floss companies use the chemical to get that effortless “glide
The Future of PFAS Analysis - What Advances are We Making in LC-MS/MS? 23:02 This video discusses the types of methodologies used for both EPA 1633 (Draft) and ASTM 8421-21 (Draft) including best practices to help you navigate sample handling and ways t...
chain by being taken up by aquatic organisms. A source of PFAS contamination can, therefore, have long-term impacts over a wide area. While the health effects of low concentrations of PFAS on humans and animals are not certain, the substances are known to bioaccumulate, and are considered ...
