Magnetic separation coupled with Pb–Cd stable isotopes to unravel geochemical background in metal(loid)-polluted areas
Pb = 17.97). Similarly, the magnetic fraction was enriched in lighter Cd isotopes (δ¹¹⁴Cd = 0.14 ± 0.02‰), consistent with fly ash signatures, while the non-magnetic fraction was heavier (δ¹¹⁴Cd = -0.34 ± 0.05‰), reflecting the geogenic background. Overall, our results demonstrate that magnetic separation constitutes an effective and relatively low-cost pre-treatment for disentangling geogenic and anthropogenic contributions in metal-contaminated soils.
