Abstract(s)
Phthalates are a class of endocrine disruptors extensively used in plastic production as plasticizers, and as a result, they
can be found in foods as a result of their migration ability. The occurrence of phthalates was monitored in 20 Portuguese wines using
a simple, reliable, and environmentally friendly analytical method, headspace solid-phase microextraction combined with gas
chromatography−mass spectrometry. Satisfactory figures of merit of method, linearity (correlation coefficient of ≥0.992), recovery
(80.3−107.6%), precision (relative standard deviation of <13%), and limits of detection (0.03−0.11 μg/L) and quantification
(0.09−0.36 μg/L) were achieved. Dibutyl phthalate and di-n-octyl phthalate were found in measurable quantities in table and
fortified wines. The obtained results revealed that these wines do not represent any concern for human exposure, because their
concentrations were lower than the tolerable daily intakes established by the European Food Safety Authority.
