THE CONTENT OF MERCURY IN EDIBLE MUSHROOMS FROM MIDDLE SPIÅ AREA

Abstract

Accumulation of total mercury by mushrooms, was studied in midle spiš area. This area is laden high contents of mercury in the soil. To determine of the contamination of edible mushrooms in the middle Spiš, we used samples of different types of edible mushrooms (Macrolepiota procera, Lecinum piceinum, Lycoperdon pyriforme, Russula sp. Suillus And Grevillea). These fungi were collected in Spišsko Gemerské-rudohorie. Here at the sampling point GPS coordinates are. We also carried out the determination of the exchange soil reaction: pH (CaCl2), soil humus content and the content of total mercury in the soil horizon A (0-15 cm). The concentration of mercury in edible mushrooms was more extreme. The highest amount of mercury 176.409821 mg.kg-1. dry matter was determined in Macrolepiota procera. Contrast, the lowest measured concentration was 0.091684 mg.kg-1. dry matter for species Lecinum piceinum. To determine the concentration of mercury in the samples, we used the device AMA 254 (Advanced Mercury Analyser).
