A multi-residue method for analysis of various endocrine disruptors in ambient air: application to urban habitats.

Abstract : Human activities involve the emission of a multitude of semi-volatile organic compounds (SVOC) in ambient air, pollutants recognized as endocrine disruptors (ED). In order to improve knowledge of ED transfer in air, a multi-residue method of sampling and analysis of micropollutants was developed. The study of gaseous and particulate phase contamination of ambient air focused upon 58 organic molecules originating from industrial synthesis: plasticizers, flame retardants, surfactants, bactericides, organochlorinated compounds and polycyclic aromatic hydrocarbons. Their identification and quantification were performed using the following devices: dynamic air sampling, analysis of gaseous and particulate phases separately by gas or liquid chromatography coupled with mass spectrometer. The instrumental detection limits were less than 1 pg for all compounds and therefore a limit of quantification around 1 pg.m-3 for gaseous and particulate phases when a indoor air volume of 150 m3 is collected, except for phthalates, phenol compounds and BDE-209. Satisfactory recoveries were found except for phenol compounds. That method was successfully applied to several outdoor samples (urban, suburban, forest) and indoor air samples (office, apartment and day nursery). Most of the targeted compounds were quantified and occurred mainly in the gaseous phase. The most abundant compounds were phthalates (> 918 ng.m-3 in total air), followed by alkylphenols > PCBs > parabens > BPA > PAHs > PBDEs. ED compounds are ubiquitous in the air of all habitats, with concentrations in indoor air almost always higher than in outdoor air, due to confinement, human activities and potential sources that will be specified
