The pollution is largely attributed to vehicle emissions, industrial activity, and construction dust. Areas like Orangi, with a PM2.5 reading of 166, and Malir, with 157, reflect the significant impact of industrial and vehicular pollution.
Vulnerable groups such as children, the elderly, and people with pre-existing health conditions are especially at risk.
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.
