Summary
Antimony (Sb) mobility in soil decreases with depth and varies by soil type. Sandy soils exhibit higher Sb migration, potentially due to soil colloids, unlike other soil types studied.
Area of Science:
- Environmental Science
- Soil Science
- Geochemistry
Background:
- Antimony (Sb) contamination from mining and smelting poses significant environmental risks.
- Understanding Sb migration in soils is crucial for environmental risk assessment and remediation.
Purpose of the Study:
- To investigate the migration patterns of antimony in various contaminated mine soil types.
- To evaluate the influence of soil properties and environmental factors on Sb mobility.
Main Methods:
- Lysimeter experiments were conducted to simulate artificial leaching and Sb migration.
- Soil Sb concentrations, chemical fractions, and soil solution Sb were analyzed.
- Environmental factors (water content, temperature, redox potential) and soil properties (Fe, Mn, Na content) were assessed.
Main Results:
- Exchangeable soil Sb decreased with artificial leaching.
- Sb concentrations in subsoil layers were highest in Isohumosol and Ferrosol, lowest in Sandy soil.
- Sb mobility decreased with soil depth, simulated by a logarithmic function.
- Sb migration in Sandy soil differed significantly, suggesting colloid transport.
- High Fe and Mn content in Ferrosol and Isohumosol reduced Sb mobility.
- Sb/Na ratios and mobility decreased in the order: Sandy soil > Primosol > Isohumosol > Ferrosol.
Conclusions:
- Soil type significantly influences antimony mobility, with Sandy soil exhibiting the highest mobility.
- Antimony migration is affected by soil depth, environmental factors, and soil composition, particularly Fe and Mn content.
- The findings provide insights into Sb fate in contaminated soils and inform risk management strategies.
