| description |
Four heavy metals (Pb, Cd, Cu and Zn) in four different commercial
mushroom species (Pleurotus ostreatus, Lentinus edodes, Hypsizygus
tessellatus and Auricularia polytricha) purchased from the local market were
detennined by Atomic Absorption Spectroscopy after microwave digestion.
The ranges of element concentrations for lead, copper. and zinc were 0.0030.009,
0.00016-0.00019 and 0.00075-0.0012 mg/kg respectively but the
cadmium content level was below the detection limit. In general, lead content
was higher than other metals in all mushroom species. All of the metal
content level were below than permissible limit that recommended by WHO.
The Hazard Index (HI) value was less than 1 for all heavy metals in Lentinus
edodes, Hypsizygus tessellatus and Auricularia polytricha while the HI value
in Pleurotus ostreatus was exceed the acceptable value, 1. The HI value for
Pleurotus ostreatus, Lentinus edodes, Hypsizygus tessellatus and Auricularia
polytricha were 1.32,0.012,0.010 and 0.046 respectively. Therefore, there is
no non-carcinogenic risk from ingestion of these four metals individually and
collectively through the three types of mushroom consumption from the
market except for Pleurotus ostreatus. |
