Karachi, Pakistan, has unfortunately earned the title of the seventh most polluted city globally, with its air quality deteriorating to unhealthy levels due to unfavorable eastern winds. The Air Quality Index (AQI) has recorded a particulate matter level of 163, posing risks to the health of Karachi’s residents.
Health experts have raised concerns about the city’s air quality, describing it as “very unhealthy” and advising the public to limit outdoor activities, especially during peak pollution periods. An AQI ranging from 151 to 200 is considered unhealthy, while readings between 201 and 300 are more harmful, and anything above 300 is deemed extremely hazardous.
During winter, the air in Karachi becomes denser, causing harmful particles to descend and pollute the atmosphere. This phenomenon results in the accumulation of pollutants like carbon and smoke, creating a layer of harmful particles that blankets the area.
Various sources contribute to this pollution, including emissions from factories, burning of coal, garbage, oil, or tires, all of which release smoke and pollutants into the air. These pollutants have a significant impact during the winter season, persisting from the beginning to the end of the season.
In light of these concerning developments, it is crucial for authorities and the public to take proactive measures to address air pollution in Karachi and safeguard the health of its residents.
