Revolutionizing PFAS Detection in Air: High Sensitivity with the Aim Reactor

Introduction

Per- and polyfluoroalkyl substances (PFAS) are man-made chemicals widely used in various industrial and consumer products for their water- and oil-resistant properties [1]. Despite being produced since the 1940s, these compounds have only gained global attention in the last decade due to their adverse effects on human health. These molecules, often labeled as 'forever chemicals' because of their resistance to natural degradation and ability to bioaccumulate in organisms, have been found in air, surface waters, oceans, soils and even in remote Arctic regions [2]. In addition, elevated concentrations of PFAS have been detected indoors, indicating an important exposure pathway for humans [3].
