Forest and meadow soils around the Bolesław smelter (Bukowno)
Lesser Poland, Olkusz district, Bukowno, Poland
Soils

- Soil
Three soil profiles about 1 km south and north of the Bolesław zinc smelter, active since 1952 and the main Tl source of the Olkusz district: forest Arenic Regosol (profile 1), meadow Rendzic Leptosol (profile 2) and forest Eutric Arenosol (profile 3). Tl decreasing with depth, up to 30 mg/kg in the forest O horizon. Surface horizons reflect light industrial Tl (ore and flotation residue near -3.8) more than 30 years after the main emission period; the Ap horizon of profile 1 and the C1 and C2 horizons of profile 3 are heavier than the source and the bedrocks (-0.98 and -1.88), a sign of fractionating sorption or precipitation. Industrial Tl makes up almost all Tl of the forest surface horizons and about half of that of the meadow (Vaněk et al., 2018). Coordinates: centre of the three profiles (Table 1: N50°16.314 E19°28.379; N50°17.063 E19°28.386; N50°16.910 E19°29.109).
