When the heat subsided, everyone thought it would be a time of comfort and that they could fully enjoy this mid-season. However, news emerged that the smog season had begun. What is this new season? You might be wondering, especially since the city of Lahore is now under the grip of smog. While the weather doesn’t seem to change much, the entire city can be enveloped in smog. A significant reason for this is the rising pollution levels.
First, it’s essential to understand what smog actually is. Smog is a mixture of toxic smoke, dust, and contaminated water vapor that pollutes the air. Generally, there are two types of smog: sulfurous smog and photochemical smog. Sulfurous smog is referred to as London smog, while photochemical smog is known as Los Angeles smog. The term “smog” was first used in the 1950s when Europe and the United States faced air pollution due to the industrial revolution. In Pakistan, smog can occur anytime from October to January, lasting in intensity for 10 to 25 days, with immediate relief typically only possible through rainfall.
As winter begins, smog is intensifying. Many people confuse fog with smog, but they are different phenomena. Fog is caused by cold weather, which is not currently likely. However, the increasing smog has notably settled in Punjab. The absence of rain in October has also contributed to the growing smog.
The Meteorological Department has expressed concerns over a significant increase in smog this year due to climate change. In an advisory, they indicated that factory pollution and vehicle emissions could contribute to the rise in smog. Typically, smog persists from November to December, but this year, climate change may lead to a notable increase in smog levels, particularly affecting cities like Lahore, Gujranwala, Sheikhupura, Kasur, and Faisalabad.
According to the Meteorological Department, the rise in smog can also harm public health and the environment. Reduced visibility during smog increases the risk of traffic accidents. Additionally, cities affected by smog may see a rise in asthma cases, particularly impacting children, the elderly, and individuals with weakened immune systems.
