LCMS 207 - Quantitation of PFAS in Water by LC-HR-QTOF MS/MS This study showcases high-resolution mass spectrometry's effectiveness in directly analyzing and quantifying multiple PFAS compounds in water samples. The study identified concentrations exceeding current EU regulatory and proposed US EPA ...
The presence of perfluoroalkyl acids (PFAAs) and chlorinated polyfluoroalkyl ether sulfonates (Cl-PFAESs) in humans has attracted great attention in recent decades. However, information on their exposure sources and the influence of age and gender on Cl-PFAES concentrations in human serum is still...
Recently, a drinking water assessment conducted by the EWG has identified Miami, Florida as the U.S city with the third highest levels of PFAS. This critical review presents a summary of the recent literature, databases, and investigations of PFAS contamination in Florida, focusing on PFAS ...
This is why we now offer water testing for 18 of these chemicals and currently accept samples from over half the states in the country. In the near future, EMSL will have even more PFAS testing options.” EMSL has also sponsored an educational video about PFAS and potential exposure risks ...
Surface water samples were collected from 20 estuary sites and 32 catchment sites in June and December from 2016 to 2018. Modelled catchment discharge was used to estimate PFAS load over the study period. Three major catchment sources of elevated PFAS were identified with contamination likely ...

Recent Findings The number of PFAS being quantified in studies involving soil, water, and plants is increasing. Transformation of precursors that tend to stay in the rhizosphere can lead to long-term PFAS reservoir to plants. Some PFAS are readily taken up, particularly the shorter-chain PFAS, ...
How can PFAS infiltrate water supplies? There are a number of ways in which PFAS can enter our water supplies. They can leach off the products in which they are contained both during and after use. Oil can be washed off bike chains by the rain, clothes ...
In the past, cases of PCDD/F and PCB contamination exceeding limits in food from animal origin (eggs, meat or milk) were mainly caused by industrially produced feed. But in the last decade, exceedances of EU limit values were discovered more frequently f
Due to the establishment of regulatory restrictions and voluntary industry initiatives on the release of long-chain perfluoro- and polyfluoroalkyl substances (PFAS) and potential precursors, alternative PFAS find increasing applications. It is estimated
