Resumo

Although parabens have been reported to be used as antimicrobial preservatives in personal care products, pharmaceuticals, and foodstuffs, little is known about the occurrence of these compounds in sports supplements. In this study, a simple, fast and sensitive liquid chromatography tandem mass spectrometry method for simultaneous determination of five commonly used parabens, methyl-, ethyl-, propyl-, butyl-, and benzylparaben in sports supplements was established. The analytical method was validated with the values of parameters being acceptable. The method proved reliable, accurate, and sensitive and was successfully applied for the quantitation of parabens in 85 sports supplements samples. Almost all sports supplements contained at least one of the parabens analyzed, and the total concentrations of five parabens ranged from below the limit of quantification to 145 mu g g-1, with a median value of 0.171 mu g g-1. Ethylparaben and methylparaben were the most frequent paraben analogs found in samples (detection rate > 60%). Propylparaben, butylparaben and benzylparaben are forbidden in food samples, their detection rates were 49.4, 21.2 and 4.7%, respectively. Therefore, our study suggests that Brazilian population may be exposed to estrogenic not allowed parabens and their harmful effects through the intake of sports food supplements. (AU)
