Chemical Solutions To Control Air Pollution: Sources, Impacts, And Mitigation Strategies

Air pollution continues to be one of the most critical environmental and public health concerns in the contemporary world. Industrialization, urbanization, fossil-fuel combustion, transportation expansion, and changing consumption patterns have increased the concentration of harmful pollutants in the atmosphere manifold. These pollutants include particulate matter, sulfur oxides, nitrogen oxides, carbon monoxide, volatile organic compounds, ozone, persistent organic pollutants, and toxic metals. In the atmosphere, they undergo chemical changes that produce secondary pollutants, ranging from photochemical smog and acid rain, which magnify their negative effects on ecosystems, human health, agriculture, and climate. This article looks at the chemical composition and pathways of global air pollutants, their health and environmental impacts, and most relevant, the chemical and technological solutions we have developed to curb them. Mainly this section will address catalytic converters, flue gas desulfurization, selective catalytic reduction, adsorption, absorption, electrostatic precipitation, cleaner fuels, green chemistry, carbon capture, and low-emission processes in industry. The paper also examines regulatory efforts, public knowledge, and preventative measures in conjunction with the use of chemical treatments. Environmental protection strategies such as pollution prevention, cleaner production processes, advanced chemical control technologies, strict policy control, and community involvement should all be included in an air quality management framework. The review suggests that though efficient solutions based on technology are effective, long-term measures to prevent and control air pollution call for systems-based approaches that include clean energy transitions, industrial innovation, environmental governance, and public behavioral change. \
