What role do wetlands play in aquatic pollution management?

Wetlands play a critical role in aquatic pollution management primarily by filtering pollutants and providing habitat for wildlife. They act as natural buffers and filtration systems, which help improve water quality. Through physical, chemical, and biological processes, wetlands can capture sediments, absorb nutrients (like nitrogen and phosphorus), and break down harmful substances before they reach larger water bodies. This filtration capability reduces the concentration of pollutants in the water, preventing the adverse effects of pollution on aquatic ecosystems and promoting healthier habitats for various plant and animal species.

In addition to their filtering functions, wetlands provide essential habitats for diverse wildlife, including fish, birds, and amphibians, contributing to biodiversity and ecosystem stability. This dual function highlights the importance of wetlands in maintaining ecological health and mitigating the impacts of pollution in aquatic environments.
