At present, human exposure to dialkyl phthalates is assessed through urinary measurement of their metabolites due mainly to contamination in their analysis by their ubiquitous presence. An on-line miniaturized method and the processing of the untreated urine samples have been the key factors for minimizing contamination and achieving unbiased results. Di(2-ethylhexyl) (DEHP), diethyl (DEP), dibutyl (DBP) and mono-ethylhexyl (MEHP) phthalates in urine samples have been included in the study; MEHP as metabolite of the main dialkyl phthalate such as DEHP. On-line in-tube solid-phase microextraction (IT-SPME)-capillary liquid chromatography (CapLC) with diode array detection (DAD) is employed. The detection limits (LODs) achieved in urine were between 0.5 and 1.5 mu g/L. Eighteen urines were processed. DBP and DEHP were found in nine and five samples, respectively and DEP in three of them. MEHP was only detected in one of the eighteen samples analyzed. (C) 2015 Elsevier B.V. All rights reserved.
