Smog is a type of air pollution which is a mixture of smoke and fog. Scientifically, smog is a mixture of different pollutants, including oxides of nitrogen (NOx), oxides of sulphur (SOx), carbon monoxide (CO), particulate matter (PM), volatile organic compounds (VOC), and the ozone. The main pollutant responsible for smog built up is NOx. This describes atmospheric condition of a particular area. In its worst form it blocks out the winter sunshine, causes closure of motorways after dusk, and prevents flights from landing at the international airports at night. Residents of that particular area face a dense blanket of smog that reduces visibility for commuters and is responsible for several respiratory and mental ailments.

Historically, the most lethal smog was the London's Great Smog in 1952. Owing to that hellacious smog, more than 12,000 people died from either traffic accidents or respiratory ailments. In 2012, Beijing faced deadly smog which resulted in large number of casualties. Over a couple of years, Pakistan and India have been badly hit by smog. In winter, with delayed rainfall, the cold and continuously dry conditions retain all the pollutants in the lower levels of the atmosphere, causing the smog to spread in both the countries.

In Pakistan, particularly in Lahore, the problem of smog has been growing worse and worse over the last five years. This problem occurs due to the high level of air pollution. Emission of smoke by the vehicles and industries, combustion of coal-based power plants and agriculture water are the main reasons of smog among too many to mention.

In Lahore, smog enters through bordering state of the Indian Punjab and Jalandhar, mainly due to setting the paddy fields on fire. According to The New York Times, farmers in these areas burn the leftover straws of the rice fields. Leftover straws can be as many as thirty-two million. For a couple of years, Lahore has been reported as the most polluted city of Asia.

• Specific mitigation measures should be adopted by the government and the policy makers to control the growing air pollution.
• Planting of more trees can mitigate the hex of these chemical gases.
