The purpose of this study was to evaluate heavy metal content of Mushrooms in Korea market. For the analysis, mushrooms are Neung-I (Sarcodon imbricatus), White Ferula Mushroom (Pleurotus nebrodensis), Song-go and Hen of the woods (Grifola frondosa). Samples were digested by microwave digestion system. This study analyzed for Pb, Cd, As and Hg by using ICP-MS (Inductively Coupled Plasma - Mass Spectrometer) and DMA (Direct Mercury Analyzer).
Linearity, LOD (limit of detection), LOQ (limit of quantitation), accuracy and precision for the analysis validation, through FAPAS (International Quality Control) was verified.
As a result, LOD was 0.00001 ~ 0.0033 mg/kg and LOQ was 0.00012 ~ 0.0109 mg/kg. Also, RSD was less than 5 %. Accuracy was 94.8 ~ 108.2% and precision was 0.14 ~ 4.30 %. FAPAS Satisfactory results were obtained below the Z-score 1.0, ensure high reliability of the analyses.
Analyzing heavy metals contents of Mushrooms, Pb, As, Hg was highest in Neung-I (Sarcodon imbricatus). Cd was highest in Hen of the woods (Grifola frondosa).
The standard of domestic heavy metals of mushrooms is 0.3 mg/kg for Pb and Cd in the case of Button (garicus bisporus (Lange) Imbach), Oyster (Pleurotus ostreatus (Jacq.) P. Kumm.), King oyster, Pyo-go (Lentinula edodes), Mok-i (Auricularia auricula-judae (Bull.) Quél.), Song-I (Tricholoma matsutake (S. Ito. & Imai.) Sing.).
As a result of the analysis, there was nothing exceeding the domestic standard specification.
