In Karachi, citizens are grappling with hazardous air pollution exacerbated by dropping temperatures. With a minimum temperature of 15.5 Celsius due to northern winds, the Met Office predicts further decreases. The city now ranks 9th on the Air Quality Index (AQI) globally, with a particulate matter reading of 156, categorizing its air quality as “very unhealthy.”
Health experts advise citizens to wear masks, limit outdoor activities, especially during peak pollution hours, and note that an AQI between 151-200 is unhealthy. Winter exacerbates the issue as denser air causes harmful particles to descend, accumulating a layer of pollutants like carbon and smoke. This phenomenon persists throughout winter, impacting citizens more at the season’s onset.
Despite southwestern sea winds typically acting as a filter for Karachi’s air, they remain suspended in winter. This situation underscores the urgent need for preventive measures and public awareness to mitigate the health risks associated with the city’s deteriorating air quality. The collaboration of citizens, authorities, and environmental initiatives is crucial to address and alleviate the complex factors contributing to Karachi’s pollution woes.
