Air pollution refers to the presence of harmful or excessive quantities of substances in the air that can have negative effects on human health, the environment, and ecosystems. These pollutants can come from a variety of sources, including vehicles, industrial processes, and natural sources like wildfires. The impacts of air pollution can be far-reaching and include respiratory issues, cardiovascular diseases, and even premature death in humans. Additionally, air pollution can harm plant and animal species, contribute to climate change, and degrade the quality of soil and water bodies. Research in the area of air pollution seeks to better understand the sources, distribution, and impacts of pollutants in the air, as well as develop strategies and technologies to reduce or mitigate their effects. This research often involves monitoring air quality, assessing health risks, studying atmospheric chemistry, and evaluating the effectiveness of pollution control measures.
