This paper presents the first study focusing on perfluoroalkyl acids (PFAAs) found in leachates and their impact on human health. Over the past few decades, PFAAs have received increasing attention due to their negative effect on human health and their persistence within the environment. This study investigates solid waste-produced leachates that are collected and treated by Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS). In the case of drinking water, the PFAAs are determined using Isotope. Dilution Anion Exchange Solid Phase Extraction and LC-MS/MS.The PFAAs found in the raw leachate under study reach concentrations of 510 ng/L. In surface water near uncontrolled areas of solid waste dumps, the concentrations of PFAAs are in the range of 15 ± 1.4 to 120 ± 2.7 ng/L. The present study estimates the chronic daily intake of PFAAs in surface water to be in the range of 0.77 to 3.6 ng/Kg/day. Based on these findings, further investigations are warranted regarding PFAA risk assessment and toxicity.
