Karachi’s air quality turns ‘unhealthy’ for first time in Nov

The air quality in Karachi turns ‘unhealthy’ on Saturday for the first time in November as smog persists in various parts of the country.

According to Air Quality Index, the air quality value soared to 212 making it third-most polluted city in the world.

The concentration of toxic PM2.5 pollutants in Karachi’s atmosphere was 27.4 times higher than the World Health Organisation’s (WHO) guidelines value, around 9:20am.

Following a slight improvement, the AQI value in the city dropped to 194.

The Swiss watchdog said that the case of Karachi’s air pollution is due to a high number of vehicles operating in the city.

Meanwhile, Lahore retained its position as the second-most polluted city, with an AQI value of 298 — just two points shy of the “hazardous” category — while the Indian capital, New Delhi topped the global pollution ranking.
