sediment toxicity

Sediment toxicity occurs when substances in the sediment—such as chemicals or pollutants—harm aquatic life. These sediments can contain contaminants from sources like industrial waste, agricultural runoff, or oil spills. Organisms living on or in the sediment, like worms or clams, can absorb these toxins, which may then affect their health, growth, or reproduction. Moreover, predators that eat these organisms can also be affected. Monitoring sediment toxicity helps assess environmental health and guides efforts to reduce pollutant risks, ensuring healthier aquatic ecosystems and safer water quality.
