Accumulation of Heavy Metals in Wild Mushrooms Found on Highways around Ilaro, Ogun State, Nigeria.
Abstract
The determination of heavy metals accumulation in mushrooms play important role in their dietary intake and therapeutic use. This study assessed the concentration of some heavy metals Zn, Fe, Ni, Pb, Hg, Cr, As, Cu, Mn, and Cd in different wild mushrooms collected from highways in Ilaro, Ogun State, Nigeria. Cortinarius cinnamomeus, Volvariella speciosa, Lepista nuda, Hypholoma fasciculare and Pleurotus florida were collected from highways around Ilaro and its environs. These mushroom species were air dried and digested using nitric acid/perchloric mixture (ratio 2:1). The result of the heavy metal concentrations in mg/kg ranged from 12.60±0.064 - 0.939±0.039 for Zn, 7.60±0.018 - 0.602±0.013 for Fe, 8.09±0.103 - 0.226±0.027 for Ni, 0.20±0.008 - 0.020±0.026 for Pb, 0.600±0.026 - 0.071±0.004 for Cr, 5.00±0.132 - 0.265±0.069 for Cu, 2.300±0.049 - 0.323±0.039 for Mn, 0.05±0.002 for Cd while Hg and As were not detected in all the mushroom samples. Zinc was the most predominant while lead was the least in all the samples. The metal concentrations in the samples were below WHO and FAO permissible limits. However, it is important to conduct frequent mushroom monitoring in order to safeguard the populace from ingesting heavy metal-laden mushrooms as food or medicine.
