Air pollution causes more than four million premature deaths worldwide each year. This pollution consists of a complex mixture of chemicals released from both human activities and natural sources, which can undergo atmospheric transformations. These pollutants significantly affect climate patterns and harm ecosystems, crops, and man-made structures. Mitigating these effects demands knowledge about emission origins and the atmospheric processes that alter them. For instance, various emission sources lead to the creation of secondary pollutants through photochemical reactions, including ground-level ozone and secondary particulate matter - both known to adversely affect human health, economic stability, and global climate. In just the United States, annual expenditures on air pollution control exceed $30 billion. Government regulations at all levels work to decrease emissions and minimize the effects of harmful substances like sulfur dioxide, nitrogen oxides, particulate matter, toxic metals, volatile organic compounds, and hydrocarbons.
