Variations in elemental and isotopic compositions of Cu, Zn, and Cd in mushrooms: are they site- or species-dependent?
Elemental and isotopic compositions of Cu, Zn, and Cd in Imleria badia mushrooms vary more by species than by site, with Cd showing site-dependent concentrations.
- Why it matters: Understanding how elemental and isotopic variations occur in mushrooms is crucial for assessing environmental contamination and nutrient cycling, yet the influence of site versus species remains unclear.
- What they did: The study analyzed Cu, Zn, and Cd isotopic ratios and concentrations in mushrooms and soils from six sites with different bedrocks, measuring isotopic fractionation and element uptake.
- The result: Findings reveal that isotopic and elemental differences are primarily species-dependent, enabling better predictions of mushroom chemistry and environmental interactions across different habitats.
