Combustion emissions research focuses on studying the pollutants released during the combustion of fossil fuels, biomass, and other organic materials. This includes analyzing the composition and quantity of pollutants such as carbon monoxide, nitrogen oxides, sulfur dioxide, volatile organic compounds, and particulate matter. Researchers in this area investigate the impact of combustion emissions on air quality, climate change, and human health, as well as develop technologies and strategies to reduce emissions and minimize their harmful effects on the environment.
