Determination of Mercury, Cadmium, Lead, Zinc, Selenium and Iron by ICP-OES in Mushroom Samples from Around Thermal Power Plant in Mula, Turkey

Scleroderma verrucosum, Stropharia coronilla, Lactarius deterrimus, Chroogomphus rutilus, Russula delica, Laccaria laccata, Clitocybe odora var. alba, Lyophyllum decastes, Coprinus comatus, Helvella leucomelaena, Melanoleuca cognata, Melanoleuca cognata, Paxina acetabulum, Clitocybe vermicularis, Sarcosphaera crassa, Rhizopogon roseolu and Thelephora caryophyllea were collected from different localities in Mula-Yataan region of Turkey. Their trace metals concentrations were determined by ICPOES after microwave digestion. The results were 0.37 +/- 0.01-5.28 +/- 0.21 for cadmium, 467 +/- 19-3,280 +/- 1 31 for iron, 0.69 +/- 0.03-9.15 +/- 0.37 for lead, 18.70 +/- 0.75-67.10 +/- 0; 2.68 for selenium, 75 +/- 3-213 +/- 8 for zinc and 0.15 +/- 0.01-0.55 +/- 0.01 for mercury (as mu g/g). The detection limits for ICPOES were found as 0.25 for Cadmium, 0.2 for iron, 0.1 for lead, 0.5 for selenium, 0.2 for zinc and 0.03 for mercury (as mg L super(-1)). The Relatively Standard Deviations (R.S.D.) were found below 4.0%. The accuracy of procedure was confirmed by certified reference material.
