Pollution is the introduction of harmful substances or contaminants into the environment, which can cause harm to living organisms, disrupt ecosystems, and degrade air, water, and soil quality. This research area encompasses a wide range of pollutants, including chemicals, toxins, greenhouse gases, and particulate matter, and examines their sources, impacts, and potential mitigation strategies. Pollution research seeks to understand the causes and effects of pollution on human health, wildlife, and the environment, and to develop policies and technologies to reduce or prevent pollution. It is an interdisciplinary field that involves collaboration between scientists, policymakers, engineers, and community members to address this global environmental challenge.
