Perfluoroalkyl substances: a risk for the aquatifc environment? A 1-year case study in river waters of central Italy.

ABSTRACT: Perfluoroalkyl substances (PFASs) are a large class of persistent emerging pollutants, ubiquitous in different environmental compartments. In this study, twenty-one PFASs were determined in seventy-eight water samples collected from six different rivers in the Umbria region (central Italy) during a 13-month monitoring campaign. The sum of the twenty-one target analytes (Σ₂₁PFASs) ranged from 2.0 to 68.5 ng L^-1, with a mean value of 22.0 ng L^-1. The highest concentrations of Σ₂₁PFASs were recorded in the warmest months (from June to September) due to reduced river streamflow caused by low rainfall and high temperatures. PFASs with a number of carbon atoms between four and nine prevail over C10-C18 congeners due to their higher water solubility and
