Arsenic, cadmium and mercury in the macrolepiota procera (Scop.) singer fruiting bodies

In this study, the content of As, Cd and Hg in fruiting bodies was determined. These three elements were determined in 94 Macrolepiota procera (Scop.) Singer samples (separately for caps and stems) and their corresponding soils/substrates collected from 8 different localities in Slovakia. Arsenic and cadmium were analyzed by Optical Emission Spectrometry with Inductively Coupled Plasma (OESICP), and mercury by Advanced Mercury Analyzer (AMA-254). In the soil/substrate As content varied from ND (not detected) to 11.9, Cd from 0.66 to 22.9 and Hg from 0.02 to 0.28 mg kg-1 DW (dry weight), respectively. | ARSENIC CADMIUM AND MERCURY IN THE MACROLEPIOTA PROCERA SCOP.

These three elements were determined in 94 Macrolepiota Revised 20. 4. 2021 procera Scop. Singer samples separately for caps and stems and their corresponding soils substrates collected from 8 different Accepted 12. 5. 2021 localities in Slovakia. Arsenic and cadmium were analyzed by Optical Emission Spectrometry with Inductively Coupled Plasma OES- Published 1. 10. 2021 ICP and mercury by Advanced Mercury Analyzer AMA-254 . In the soil substrate As content varied from ND not detected to 11.9 Cd from 0.66 to 22.9 and Hg from 0.02 to 0.28 mg kg-1 DW dry weight respectively. In fruiting body stems arsenic content varied from ND to 4.77 cadmium from ND to 5.96 and mercury from 0.03 to 2.83 mg kg-1 DW. In the caps As content varied from ND to Regular article 13.0 Cd from ND to 19.8 and Hg from 0.04 to 4.00 mg kg-1 DW. After comparing obtained results with the EU limits for As in mushrooms 6.6 cap of analyzed samples exceeded the limit value while for Cd 4.7 cap 2.0 stem of analyzed samples exceeded the limit value.
