[en] Parabens, benzophenone-3 (BP3) and phthalates are commonly used as antimicrobial conservator, UV-filter and plasticizer respectively, and are thought to exhibit endocrine disrupting properties. These endocrine disrupting activities have been recently assumed to lead to cutaneous malignant melanoma. Humans are exposed to these chemicals through different sources such as food, personal care products or cosmetics. In this study we measured urinary levels of 4 parabens, BP3 and 7 metabolites of phthalates in samples collected from 261 participants living in and around Liege (Belgium). The analyses were carried out by liquid chromatography tandem mass spectrometry (LC-MS/MS) using isotopic dilution. To the best of our knowledge, this is the first time that the urinary levels of these 3 classes of chemicals are reported for the same general population in Belgium. Most of the parabens, the BP3 and all the phthalate metabolites were detected in 82.8 to 100.0% of the samples. For most of these chemicals, the exposure patterns significantly differ between children and adults, but also between males and females, especially with higher concentrations of parabens and phthalate metabolites in female and children subjects respectively.
