From Industry to Tap: Quantifying PFAS in Drinking Water

Introduction

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a group of chemicals made by humans. Since the 1950s, PFASs have been used in many consumer products and industrial processes. They have properties that resist heat, grease, and water. There are thousands of types of PFAS. The most common types and final products of degradation are PFOA (perfluorooctanoic acid) and PFOS (perfluorooctanoic sulfonic acid). They were widely detected in different environmental media (Mahiba Shoeib et al. 2005) and human blood (Perez et al. 2013). The goal of this presentation is to develop an automated sample preparation of drinking water sample and a rapid analytical method to analyze PFAS using LDTD-MS/MS.
