在多年的工业发展中，土壤系统受到了大量有毒金属的污染。为了研究金属从土壤到蘑菇的移动性和有效性，测定了塞尔维亚中部Rasina地区5个采样点野生食用菌菌盖、菌柄和土壤基质中Al、Ba、Cd、Co、Cr、Cu、Fe、Mn、Ni、铅、锶、钛、锌等13种元素的含量。土壤样品经过社区参考局建议的顺序提取程序，以分级酸溶/可交换、可还原、可氧化和残留的组分。用电感耦合等离子体光发射光谱仪和电感耦合等离子体质谱仪测定金属浓度，并对测定结果进行多元数据分析。主成分分析区分了不同地理区域的蘑菇样品，揭示了土壤成分对蘑菇中金属含量的影响。系统聚类分析证实，提取的前三个阶段是蘑菇从土壤中吸收金属的最重要的阶段。还计算了每种金属的生物浓缩系数和迁移系数。这些结果表明，m。食用菌可作为必需元素的良好膳食来源，尤其是铜、锌、锰和铁，但在蘑菇季节食用蘑菇可能会对消费者的健康构成风险，因为镉的存在。
During many years of industrial development, soil system was contaminated with large amounts of toxic metals. In order to investigate the mobility and availability of metals from soil to mushrooms, the content of 13 elements (Al, Ba, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Sr, Ti, and Zn), in caps and stipes of wild-grown edible mushroomMacrolepiota proceraand soil substrates, collected from five sites in Rasina region in central Serbia, was determined. Soil samples were subjected to the sequential extraction procedure proposed by the Community Bureau of Reference in order to fractionate acid-soluble/exchangeable, reducible, oxidizable, and residual fractions. Metal concentrations were determined by inductively coupled plasma optical emission spectrometer and inductively coupled plasma mass spectrometer and the results subjected to multivariate data analysis. A principal component analysis distinguished mushrooms samples from different geographical areas and revealed the influence of soil composition on metal content in mushrooms. Hierarchical cluster analyses confirmed that the first three phases of extraction were the most important for metal uptake by mushrooms from soil. The bioconcentration factors and translocation factors for each metal were also calculated. These results showed thatM. proceracould serve as a good dietary source of essential elements, especially Cu, Zn, Mn, and Fe but the consumption of mushrooms may pose a health risk for consumers during the “season of mushrooms,” due to the presence of cadmium.
