AI Technical Summary
The migration and transformation patterns of chromium pollutants in leather tanning sites are difficult to quantify, and the influence of coexisting substances on the chromium migration process is unclear, leading to difficulties in remediation and the occurrence of yellowing. There is a lack of scientific basis for quantifying the distribution patterns of pollutants and assessing health risks.
Based on reactive solute transport, a dynamic risk assessment method for leather tanning contaminated sites is constructed, including soil and groundwater migration models. Combined with thermodynamic database analysis, pollutant migration and transformation are assessed to evaluate static and dynamic exposure risks and provide risk management and remediation strategies.
The system assesses the spatiotemporal variations of chromium in leather tanning sites, providing a scientific basis for developing reasonable risk management and environmental protection strategies, optimizing site remediation measures, and reducing health risks.
