    Summary

    Wild mushrooms in Germany show varying lead levels, with an average of 10.6 mg/kg dry weight. This study analyzed 222 species to assess heavy metal contamination in edible and poisonous fungi.

    Area of Science:

    • Environmental Science
    • Mycology
    • Analytical Chemistry

    Context:

    • Wild mushrooms are a significant food source in many regions.
    • Heavy metal contamination in edible organisms is a public health concern.
    • Southern Germany's rural areas were selected for mushroom sampling.

    Purpose:

    • To quantify the lead content in a diverse range of wild mushroom species.
    • To assess potential dietary exposure to lead from mushroom consumption.
    • To establish baseline lead levels in wild fungi from Germany.

    Summary:

    • Lead concentration was measured in 494 samples from 222 wild mushroom species using graphite furnace atomic absorption spectroscopy.
    • Lead levels ranged from <2.0 to 40.4 mg/kg dry weight (average 10.6 mg/kg).
    • Fresh weight concentrations averaged 1.06 mg/kg, with a range of <0.1 to 3.0 mg/kg.

    Impact:

    • Provides crucial data on lead contamination in wild mushrooms.
    • Informs risk assessments for consumers of wild fungi.
    • Contributes to understanding heavy metal bioaccumulation in the mycota.
