title: Pilot study on levels of perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) in selected foodstuffs and human milk from Italy.
abstract: Despite the health risks associated with perfluorinated compounds (PFC) exposure and the detection of these compounds in many countries around the world, little is known on their occurrence in Italy. The results of a study on levels of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), analysed by HPLC-ESI-MS, in human milk and food samples from the city of Siena and its province (central Italy) are here reported. PFOS was found in 13 out of 49 breast milk samples (0.76±1.27 ng/g), while PFOA was detected in one sample (8.04 ng/g). Only PFOS was found in food samples. Fish were the most contaminated samples (7.65±34.2 ng/g); mean concentrations in meat and milk and dairy products were similar (1.43±7.21 ng/g and 1.35±3.45 ng/g, respectively). In all cereal-based food, eggs, vegetables, honey and beverages PFOS concentration was <LOD. These data show that consumption of most breast milk analysed would not result in children exceeding their total daily intakes for perfluorinated compounds.
