Shahra-e-Faisal and Clifton recorded levels of 157 and 154, making outdoor activity risky. Gardens and Gulistan-e-Johar were similarly polluted, with indices of 163 and 151.
This alarming situation is driven by winter smog trapping vehicle exhaust and industrial emissions.
Weather conditions prevent pollutants from dispersing, creating a toxic blanket over the city. The concentration of fine particles is critically high.
Health experts warn these dangerous PM2.5 levels can penetrate lungs and enter the bloodstream.

How many categories are there to measure Air Quality?
AQI 0–50: Good
The air quality is considered excellent, with minimal or no risk to public health. There are no necessary precautions for the general population.
AQI 51–100: Moderate
Air quality is generally acceptable; however, there may be a slight health concern for a small number of individuals who are unusually sensitive to air pollution. Active children, adults, and people with respiratory conditions like asthma should consider limiting prolonged outdoor activity.
AQI 101–150: Unhealthy for Sensitive Groups
Sensitive individuals, such as those with asthma or other respiratory issues, may begin to experience health effects, although the general population is unlikely to be affected. It is advised that active children, adults, and those with respiratory conditions limit extended outdoor exertion.
AQI 151–200: Unhealthy
Health effects may begin to affect everyone, with sensitive groups potentially experiencing more serious symptoms. Active children and adults, and people with respiratory illnesses should avoid prolonged outdoor activity, while others—especially children—should reduce outdoor exertion.
AQI 201–300: Very Unhealthy
This range signals emergency-level health warnings. The entire population is more likely to experience adverse health effects. Those with respiratory conditions and active individuals should avoid all outdoor activity, while everyone else, particularly children, should limit time spent outdoors.
