Black Triangle forest and meadow soils (southeast of Turów)

- Soil
Two profiles about 50 m apart, about 12 km southeast of the Turów (Poland, 2000 MW) and Hirschfelde (Germany, 1911-1992) lignite power plants. Light thallium from high-temperature emissions (fly ash, vapours) accumulates in the surface horizons, over a heavier geogenic background (ε205Tl about -1); binary mixing between these two reservoirs (Vaněk et al., 2016). Published coordinates.

| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| −1.53 ± 0.79 ε | −2.3 / −0.16 ε | 6 | forest soil (profile F, L to C horizons) Mean and standard deviation recalculated from 6 analyses, L, F+H, A, AB, Bw and C horizons; minimum of -2.30 in the A horizon, heavy Tl-poor L litter (-0.16). | Vaněk et al.

| −1.77 ± 0.83 ε | −2.53 / −0.61 ε | 5 | meadow soil (profile M, A1 to C horizons) Mean and standard deviation recalculated from 5 analyses, A1, A2, AB, Bw and C horizons; light anthropogenic Tl at the surface, heavier Bw (possible sorption on Mn oxides). | Vaněk et al.
