DOC-governed metal solubility and mobility in river sediments: Integrating machine learning, causal pathways, and geochemical simulations

Key Points

• Metal solubility correlates with dissolved organic carbon (DOC) levels in river sediments, influencing mobility.
• A combination of machine learning algorithms and geochemical simulations predicts metal behaviors with high accuracy.
• Geochemical assessments utilize causal pathways to understand interactions within sediment and metal dynamics.
• Understanding these interactions is crucial for environmental assessments and pollution control strategies.
