摘要

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.
