Abstract

The plastic manufacture compounds, bisphenol A (BPA) and phthalates, are ubiquitous and have therefore been detected in virtually all types of analyzed human samples. The aim of this study was: (1) to investigate concentrations of serum levels of BPA and phthalate metabolites in seniors residing in the city of Uppsala, Sweden (2) to evaluate gender differences in relation to serum levels of BPA and phthalate metabolites in the subjects. In the population-based Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS), encompassing 1016 subjects, all aged 70, serum levels of BPA and phthalate metabolites were measured by Isotope Dilution-High Performance Liquid Chromatography-Tandem Mass Spectrometry. BPA and four out of ten phthalate metabolites, namely, Monoisobutyl phthalate (MiBP), Monomethyl phthalate (MMP), Monoethyl phthalate (MEP), Mono-(2-ethylhexyl) phthalate (MEHP), were detectable in almost all subjects. Of the remaining phthalate metabolites, Monobenzyl phthalate (MBzP), Mono-(2-ethyl-5-hydroxyhexyl) phthalate (MeHHP), and Mono-(2-ethyl-5-oxohexyl) phthalate (MEOHP) were seen in some 300-700 of the subjects, whereas Monoisononyl phthalate (MINP) and Mono-n-octyl phthalate (MOP) were found in only a few and Monocyclohexyl phthalate (MCHP) was not detected in any subject. Neither the circulation levels of BPA nor those of phthalate metabolites differ between the genders in this elderly population of residents in Uppsala, Sweden.
