【 摘 要 】

Per- and polyfluoroalkyl substances (PFASs) comprise a large array of man-made fluorinated chemicals. It is an emerging chemical class of concern because many PFASs are environmentally persistent and some have known ecological and human toxicity. Consumer products treated with PFASs result in human exposure to PFASs through inhalation, ingestion, and environmental exposure to emissions from wastewater or from landfills. A rapid screening method based on total fluorine was developed and applied to quantify PFASs on consumer papers and textiles. Particle-Induced Gamma Ray Emission (PIGE) spectroscopy provides a non-destructive and quantitative measurement of total fluorine on papers and textiles. This technique is both rapid and sensitive, with a limit of detection (LOD) of 13 nmol F/cm(2) for papers and 24-45 nmol F/cm(2) for textiles, with reproducibility of 12% RSD for both. PIGE is a high throughput (>20 samples/hr typically) method that was applied to 50 papers and 50 textiles in commerce to demonstrate the method. (C) 2017 Elsevier B.V. All rights reserved.
