Abstract
Wild macrofungi were collected in the three different sites of Tumauini, Isabela for the detection of the presence of lead (Pb) and mercury (Hg) using cold vapor and flame atomic absorption spectrometer. The collected species include Agaricus bisporus, Cystolepiota spp., Pycnoporus spp., Lentinus tigrinus, versicolor, Ganoderma lucidum, Trametes hirsuta, Paneolus spp., Species 9, Species 10, and Species 11. Among the eleven macrofungi, eight showed the presence of lead namely: A bisporus, Cystolepiota spp., Pycnoporus spp. recorded the highest amount of lead (15 mg / kg) while L. tigrinus had the lowest (1.5 mg / kg). Four macrofungi were detected to contain mercury namely: A bisporus, Cystolepiota spp., T. versicolor, and Species 11, in which Species 11 had the highest amount of mercury (1.4 mg / kg). The mercury content of the four samples were found higher than the acceptable amount of mercury in the bloodstream (0.01 mg / kg). Therefore, people should be cautious of eating wild mushrooms since they might contain heavy metals naturally accumulated from their substrates.
