The levels of calcium, magnesium, iron, manganese, lead, chromium and cadmium in four prevalent mushroom species in South Africa, namely two edible Agaricus bisporus species, one inedible Agaricus xanthodermus species and a poisonous type mushroom, Rezhina undulata are reported. Analytical results from the open vessel and microwave digestion approaches were compared. While higher levels of Ca and Mg were found in the edible types, the inedible and poisonous type mushrooms had relatively high levels of manganese, chromium, cadmium and lead. Agaricus xanthodermus had Ca (204), Mg (660), Fe (306), Mn (30), Cr (16.2), Pb (50.6) and Cd (29.5) mg kg(-1) by dry weight, while Rhizina undulata, which grows on dead wood recorded Ca (121), Mg (517), Fe (130), Mn (30.7), Cr (32.1), Pb (49.5) and Cd (20) mg kg(-1) by dry weight.
报告了南非四种常见蘑菇中的钙、镁、铁、锰、铅、铬和镉含量，这四种蘑菇分别是两种可食用的双孢蘑菇、一种不可食用的黄皮蘑菇以及一种有毒蘑菇波纹韧伞。比较了敞口容器消解和微波消解方法的分析结果。虽然在可食用类型蘑菇中发现了较高水平的钙和镁，但不可食用和有毒类型的蘑菇中锰、铬、镉和铅的含量相对较高。黄皮蘑菇干重下钙含量为204毫克/千克、镁含量为660毫克/千克、铁含量为306毫克/千克、锰含量为30毫克/千克、铬含量为16.2毫克/千克、铅含量为50.6毫克/千克、镉含量为29.5毫克/千克，而生长在枯木上的波纹韧伞干重下钙含量为121毫克/千克、镁含量为517毫克/千克、铁含量为130毫克/千克、锰含量为30.7毫克/千克、铬含量为32.1毫克/千克、铅含量为49.5毫克/千克、镉含量为20毫克/千克。
