Air quality research focuses on monitoring and analyzing the composition of the air to assess the levels of pollutants and their impact on human health and the environment. This research area deals with identifying sources of air pollution, measuring air quality indicators such as particulate matter, ozone, nitrogen oxides, and volatile organic compounds, and developing strategies to improve air quality through regulations, policies, and technological interventions. Studies in this field also explore the effects of air pollution on respiratory diseases, cardiovascular health, and overall well-being, as well as potential solutions to mitigate the negative impacts of poor air quality on human health and the environment.
