这项研究揭示了采矿和冶炼活动造成的地球化学环境扰动与消费者接触有毒和致癌金属微量元素之间的联系。本研究从居民镉、铅、锌暴露的角度，对家庭菜园蔬菜和土壤污染进行了评价。研究材料包括位于波兰污染最严重地区之一的FAGs的219个土壤样本和64个可食用植物样本。研究区表层土壤MTEs含量具有空间多样性，主要取决于工业污染源的位置。蔬菜中镉（0.52毫克/千克鲜重）和铅（0.57毫克/千克鲜重）的平均含量超过了欧洲质量标准规定的最高允许浓度。人类健康风险评估基于三种膳食暴露于镉、铅和锌的情景。在每一种情况下，马铃薯是波兰人饮食的主要组成部分之一，估计所有三种元素的最高平均日剂量。提出的研究表明，消费位于西里西亚省的FAG种植的蔬菜可能会对消费者构成重大的健康风险。
The study reveals links between disturbed geochemical environment being the result of mining and smelting activities with consumers exposure to toxic and carcinogenic metallic trace elements (MTEs). This study focused on evaluation on vegetable and soil pollution in family allotment gardens (FAGs), considering in the aspects of consumer exposure to cadmium, lead and zinc. Study material consisted of 219 soil samples from FAGs located in one of the most polluted areas in Poland, and 64 samples of edible plants. Contents of analyzed MTEs in topsoil in the studied area were spatially diversified and depended primarily on the location of industrial pollution sources. The average content of cadmium (0.52 mg kg(-1) fresh weight) and lead (0.57 mg kg(-1) fresh weight) in vegetables exceeded maximum permissible concentrations according to the European Quality Standards. Human health risk assessment was based on three scenarios of dietary exposure to cadmium, lead and zinc. In every scenario the highest average daily dose for all three elements was estimated for potatoes which are one of the main components of Poles' diet. Presented study showed that consumption of vegetables cultivated in FAGs located in Silesia Province may pose a significant health risk for their consumers.
