    This study analyzed trace elements in Slovenian fungi, finding high cadmium and mercury levels. Fungi show potential for environmental monitoring due to their accumulation patterns.

    Area of Science:

    • Environmental Science
    • Mycology
    • Analytical Chemistry

    Background:

    • Trace element concentrations in higher fungi are not well-documented.
    • Understanding these levels is crucial for ecological and toxicological assessments.

    Purpose of the Study:

    • To determine the concentrations of ten trace elements (As, Br, Cd, Cu, Hg, Mn, Se, Zn, V) in Slovenian fungi.
    • To compare fungal trace element levels with soil concentrations.
    • To explore potential applications of fungi in environmental studies.

    Main Methods:

    • Neutron activation analysis was used to quantify trace elements in 27 fungal species.
    • Data were collected from multiple sites in Slovenia.
    • Statistical correlation analysis was performed on element pairs.

    Main Results:

    • High concentrations of mercury (Hg) and significant cadmium (Cd) accumulation (average 5 ppm) were observed in most fungi.
    • Specific accumulations included bromine (Br) in Amanita genus and selenium (Se) in Boletus species.
    • Strong correlations were found between copper (Cu) and mercury (Hg), and selenium (Se) and arsenic (As).

    Conclusions:

    • Fungal trace element profiles provide valuable biochemical insights.
    • The observed accumulation patterns suggest fungi's potential utility in environmental biomonitoring.
    • This research establishes baseline data for trace elements in Slovenian basidiomycetes.
