What effect does dilution have on the toxicity of sediment?

Dilution can significantly alter the exposure of organisms to contaminants present in sediment. When sediment is diluted, the concentration of toxic substances is reduced, which may lower the potential for harmful effects on organisms. However, dilution does not uniformly decrease toxicity for all scenarios, as different organisms have varying levels of sensitivity to toxins. Additionally, the distribution and bioavailability of the toxins may change as a result of dilution, affecting how organisms interact with these substances. Therefore, understanding that dilution impacts exposure is critical for assessing the risk posed by sediment toxicity to aquatic life and ecosystems.
