Officials of the Rescue 1122 said that both the accidents took place because of smog.

Last month, 13 people were killed after a fire broke out in a passenger van after it collided with another vehicle on the Narowal Road near Sheikhupura's Narang Mandi.
Smog is formed by a mixture of pollutants and water vapor in the atmosphere. It can cause health problems such as asthma, flu, coughing, allergies, bronchial infections, and heart problems.
Prolonged exposure to environmental pollution also results in shortened life expectancy. These risks may be reduced by wearing masks, managing gaseous vehicular emissions, using eco-friendly products, and reusing and recycling.
