Gas chromatographic–mass spectrometric validated method for the determination of Bisphenol A in public-supply water: An investigation in Campo Grande, MS, Brazil

摘要

A new validated method is described for determining bisphenol A (BPA) in surface and public-supply water samples. Recovery rates of 91% to 113%, with coefficients of variation below 8.9%, were obtained within the limit of detection (2.4 ng L–1). Concentrations of 13 to 113 ng L–1 were found in tap water. An analysis of BPA stability in solid-phase extraction cartridges revealed that the analyte can be stored in such containers for at least 90 days. An evaluation of BPA leached from polyvinyl chloride (PVC) piping showed that BPA can contaminate water distribution systems.
