The emission of a combination of tiny droplets and greenhouse gases into the atmosphere is referred to as air pollution. Particles may be deposited by automobile emissions, industrial toxins, dust, allergies, and dust mites. Ozone is a pollutant-emitting gas. The term "smog" refers to ozone-induced air pollution. There may be toxic contaminants in the air. Both biological and man-made factors contribute to air pollution. The airborne particles which thus make up air pollution are recognized to be harmful to human health. Subgroups of persons have been shown to be more sensitive to inhaled environmental pollutants, such as the elderly, children, but those with lung-related illnesses (e.g., asthmatics). Air pollution has a negative impact on our environment, according to a recent research. Most developed countries across the world have passed regulations to reduce the sickness burden associated with polluted air, and evidence from epidemiological and toxicological study demonstrates that lower smog concentrations lead to better health outcomes.
