Air pollution is a severe issue in the world's most-populated cities, particularly in South Asia, where smog events have had significant health impacts, prompting authorities to take urgent actions.
Smog, a mix of 'smoke' and 'fog', arises from the combination of ground-level pollutants and fog under sunlight, creating a toxic haze with serious health risks.
Public health experts express concern that while India has clean air policies, the implementation is hindered by a lack of commitment from some authorities to meet air quality targets.
Particulate matter, identified by size categories such as PM10 and PM2.5, consists of microscopic particles released from various combustive processes, posing serious inhalation dangers.
