ABSTRACT

Air pollution is described as the presence of any chemical, physical, or biological substance in the interior or outdoor environment that alters the atmosphere's normal properties. It is to blame for a lot of the health issues in cities. Regarding the amounts of pollutants and the steps taken to remove them, Delhi's air quality has undergone numerous modifications. The condition of air pollution in Delhi, its sources, its effects on human health and the environment, and the control mechanisms put in place are all discussed in this study paper. India is the fifth most polluted country in the world in terms of air pollution, and Delhi is among the top 50 most polluted cities worldwide. The annual average PM2.5 level in Delhi was higher in 2021 than it was in 2020, although it was still lower than the levels of 98.6 g/m3, 113.5 g/m3, and 108.2 g/m3 recorded in 2019, 2018, and 2017. November saw the city's highest PM2.5 level (224.1 g/m3) and the lowest (30.2 g/m3). The average concentration was almost six times the WHO recommendation of 5 g/m3 even at its lowest point. Delhi's interior and outdoor air pollution was caused by industrial operations and vehicle emissions. Numerous studies have shown that air pollution in Delhi contributed to an increase in all-natural cause death and morbidity. While Delhi has made several hopeful improvements in the last 10 years to lower the city's air pollution levels, more work needs to be done in this area if the levels of air pollution are to be further reduced.
