Air Pollution and Control Measures in the Department of Environmental Science
Air pollution refers to the presence of harmful substances in the air that can affect human health, ecosystems, and the climate. These substances include gases (e.g., carbon dioxide, sulfur dioxide, nitrogen oxides), particulate matter, volatile organic compounds (VOCs), and other pollutants. Air pollution is a significant environmental concern studied within the Department of Environmental Science, where control measures, advanced technologies, and sustainable solutions are developed to mitigate its impact.
