Air quality across many Indian cities remains at “unhealthy” to “hazardous” levels today, with particulate-matter (PM2.5) concentrations spiking alarmingly. Authorities and health experts have alerted residents, especially vulnerable groups such as children, the elderly and those with respiratory issues, to reduce outdoor exposure. Masks and air purifiers are being advised, and public-health advisories urge minimal outdoor activity. The pollution spike has triggered calls for urgent policy and environmental action, as well as renewed public focus on clean-air measures.
