Popis: Per- and polyfluoroalkyl substances, known as PFAS, are emerging contaminants detected in surface water, groundwater, drinking water, air, and food. Due to its chemical stability and high hydrophobicity, these compounds are used as surfactants, surface protectors, flame retardants, textile impregnation, fire-fighting foam, and pesticides and may be a risk for human health in the long-term exposure. Currently, a little research has been carried out for these compounds in Brazil. In this study, the concentration and distribution of 23 PFAS were analyzed in groundwater samples collected from water wells in urbanized areas and in surface water samples from Porto Alegre, one of the biggest cities in Brazil. The total concentrations of PFAS (ΣPFAS) in a groundwater sample varied between 22 and 718 ng L
