Hence, this work assesses the content for quality and toxic metals of olive oils from three major Portuguese cultivars (\u2018Galega\u2019, \u2018Cobran\u00e7osa\u2019 and \u2018Picual\u2019) obtained from olives in different ripening stages. This evaluation was achieved by flame atomic spectrometry and atomic absorption in a graphite furnace, depending on the metal to be analysed. The results showed mean concentrations of the mineral nutrients Ca and Mg of 20.00 \u00b5g g<jats:sup>\u22121<\/jats:sup>, and K and Na of 40.00 and 170.00 \u00b5g g<jats:sup>\u22121<\/jats:sup>, respectively, while the trace elements Fe, Co, Cu, Mn, Zn and Ni had mean values of 0.53, \u2264 0.01, 0.33, 0.10, 1.09 and 0.64 \u00b5g g<jats:sup>\u22121<\/jats:sup>, respectively. The mean content of the toxic metals Al, Cd, Pb and As were 27.46, 0.03, 0.09 and 0.36 \u00b5g g<jats:sup>\u22121<\/jats:sup>, respectively, which were according to the values proposed by European regulations. The evaluation of the data obtained by partial least square regression allowed the identification of the minerals with the strongest potential to discriminate between the season (Na, Cu, Zn and Ni) and the cultivar employed in the olive oil performance (Fe and Mn).<\/jats:p>","DOI":"10.1007\/s11746-016-2827-4","type":"journal-article","created":{"date-parts":[[2016,4,14]],"date-time":"2016-04-14T04:57:29Z","timestamp":1460609849000},"page":"813-822","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Effect of Agro\u2010Environmental Factors on the Mineral Content of Olive Oils: Categorization of the Three Major Portuguese Cultivars"],"prefix":"10.1002","volume":"93","author":[{"given":"Irene","family":"Gouvinhas","sequence":"first","affiliation":[{"name":"Centre for the Research and Technology of Agro\u2010Environmental and Biological Sciences University of Tr\u00e1s\u2010os\u2010Montes and Alto Douro (CITAB\u2010UTAD) Vila Real 5001\u2010801 Portugal"}]},{"given":"Ra\u00fal","family":"Dom\u00ednguez\u2010Perles","sequence":"additional","affiliation":[{"name":"Centre for the Research and Technology of Agro\u2010Environmental and Biological Sciences University of Tr\u00e1s\u2010os\u2010Montes and Alto Douro (CITAB\u2010UTAD) Vila Real 5001\u2010801 Portugal"}]},{"given":"Nelson","family":"Machado","sequence":"additional","affiliation":[{"name":"Centre for the Research and Technology of Agro\u2010Environmental and Biological Sciences University of Tr\u00e1s\u2010os\u2010Montes and Alto Douro (CITAB\u2010UTAD) Vila Real 5001\u2010801 Portugal"}]},{"given":"Teresa","family":"Carvalho","sequence":"additional","affiliation":[{"name":"National Institute for Agricultural and Veterinary Research (INIAV) Elvas Portugal"}]},{"given":"Carlos","family":"Matos","sequence":"additional","affiliation":[{"name":"Chemistry Department University of Tr\u00e1s\u2010os\u2010Montes and Alto Douro (UTAD) Vila Real 5000\u2010801 Portugal"}]},{"given":"Ana I.
