How Does Sedimentation Affect the Toxicology of Pollutants?
Pollutants in water bodies can attach to suspended particles, which eventually settle as sediment. This process can either sequester pollutants, reducing their immediate availability in the water column, or it can lead to the accumulation of toxicants in sediments. Over time, these sediments can release pollutants back into the water, especially when disturbed by natural or anthropogenic activities. This makes sedimentation a significant factor in the bioavailability and toxicity of contaminants.
