Former acting EPA research chief Jennifer Orme-Zavaleta says detection of per- and polyfluoroalkyl substances (PFAS) is “central” to research into the chemicals’ toxicity and ways to safely destroy them, adding new urgency to the debate on whether the agency should use TSCA reporting mandates...
Water utilities play a significant role in PFAS mitigation by incorporating detection, monitoring, and treatment techniques into their operations. Many methods for PFAS analysis are in place. A detailed explanation and comparison of each can help utilities determine the best approaches for their ...
Watch this video to hear Molly Cyr, PerkinElmer Application Scientist, discuss how PerkinElmer solutions can assist labs in developing methods for PFAS regulations. Run time: 2:25min Overcoming PFAS Challenges - Method Development for Changing PFAS Regulations ...
Adsorption using covalent organic frameworks (COFs) is very effective and favoured for removing per- and polyfluoroalkyl substances (PFAS) from various matrices. The prominent classes of COF, their synthesis methods, and their application in COF-based technologies for PFAS adsorption in myriad environm...

reference allele frequency for each site. 6.1.7. Variant Detection. Paired-end reads were aligned to the human hg19 genome with BWA 0.6.2-r126 (Iyer, G., et al., 2012, Science, 338: 221). Local realignment at indel regions and baseQ raclibration was done using the GATK suite version...
INAA and PIGEhad the advantage of being nondestructive, while CIC displayed thelowest detection limits. Inconsistencies between the methods arosedue to the high aluminum content in the CRM, which precluded its analysisby INAA, and sample heterogeneity (i.e., coating on the surface ofthe material...
The composition allows for the rapid, sensitive detection of perfluorinated-alkyl substances (PFAS) by utilizing the competitive interactions during capillary action. The composition comprising one or more cellulose fibers; and one or more biomolecules associated with the one or more cellulose fibers, ...
In order to monitor the concentrations of PFAS contaminants precisely, suitable extraction methods were compared focusing on the matrix effects and characters of green analytical chemistry during the detection of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) existing with several common...
Since the detection of per- and polyfluoroalkyl substances (PFAS) in humans and different environmental media in the last two decades, this substance group has attracted a lot of attention as well as increasing concerns. The fluorine mass balance approach, by comparing the levels of targeted ...
