In order to assess the importance of vegetables cultivated in industrialized regions in Greece as a dietary factor, the daily intake of trace elements and PAHs via vegetables were estimated. Intake estimations were based on vegetable availability data and analyses of vegetable contaminants. The mean daily intake of potentially toxic elements ranged between 1.7% (for As) and 23.6% (for Pb) the provisional tolerable daily intakes for adults. Vegetables were found to contribute significantly to the recommended daily intake of essential elements, such as Cr and Mn. The intakes of Cr, Pb, Zn, Co and Hg were highest in spring, whereas the intakes of As and Se were highest in winter. The daily intake of PAHs via vegetables was in general low. The potential doses of carcinogenic PAHs was at the lower range of estimates worldwide.
为评估希腊工业化地区种植的蔬菜作为饮食因素的重要性，对通过蔬菜摄入的微量元素和多环芳烃的每日摄入量进行了估算。摄入量估算基于蔬菜可获得性数据以及蔬菜污染物分析。成人潜在有毒元素的平均每日摄入量在成人暂定每日耐受摄入量的1.7%（砷）至23.6%（铅）之间。发现蔬菜对铬和锰等必需元素的推荐每日摄入量有显著贡献。铬、铅、锌、钴和汞的摄入量在春季最高，而砷和硒的摄入量在冬季最高。通过蔬菜摄入的多环芳烃的每日摄入量总体较低。致癌多环芳烃的潜在剂量处于全球估计范围的较低水平。
