Karachi’s clean air streak ended Wednesday as pollution climbed back into hazardous ranges. Several districts re-entered the “Unhealthy for Sensitive Groups” category.
Gulshan-e-Iqbal Block 14 recorded the worst air at 152, firmly in the “Unhealthy” zone. This reading poses risks to all residents, not just vulnerable populations.

University Road (126) and North Nazimabad (108) also showed significant deterioration. Both areas are now “Unhealthy for Sensitive Groups,” requiring caution for children and the elderly.
Shahra-e-Faisal remained clean at 63, while Mauripur was moderate at 93. This air quality decline was not uniform, leaving some pockets of clean air.
The three-day forecast predicts this elevated trend will continue, then improve slightly. Levels are expected to stay in the “Sensitive” range through the weekend.

Karachi Air Quality
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.

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.
