Contaminants can be transported in sediments through processes like diffusion and bioturbation.
Measuring flux is crucial for understanding contaminant release from sediment surfaces.
Evidence-based assessments are essential for effective remediation strategies and legal accountability.
The process of organism activity in sediment that results in the mixing and transport of particles.
The transport of a substance through a medium, often caused by the movement of the medium itself, such as water flow.
The determination of the quantity of contaminants being released from a surface over a specific period.
The change in concentration of a substance across a distance, indicating the direction of contaminant movement.
