Pollution remediation is a field of research focused on developing methods and technologies to clean up and reduce pollution in various environments, such as air, water, and soil. This research area includes studying the sources and impacts of pollution, as well as designing and implementing solutions to mitigate pollution and restore environmental quality. Methods of pollution remediation can range from physical and chemical treatments, to biological remediation using microorganisms or plants. The goal of pollution remediation research is to protect human health and ecosystems, and promote sustainable development.
