Smog has become a significant environmental and health issue in Pakistan, particularly in major cities like Lahore. The primary reasons for smog in Pakistan include industrial pollution, vehicle emissions, crop burning, and adverse weather conditions. Factories and industries release large amounts of pollutants, such as nitrogen oxides and sulphur dioxide. A high number of vehicles, especially older and poorly maintained ones, contribute significantly to air pollution. Farmers burn crop residues, especially in Punjab, releasing harmful pollutants into the air. During winter, temperature inversions trap pollutants close to the ground, exacerbating smog levels. Statistics and reports paint a stark picture. Lahore often tops the list of the world’s most polluted cities, with Air Quality Index (AQI) levels frequently exceeding 300, indicating hazardous air quality. Lahore’s PM2.5 concentration is 14.6 times the World Health Organization’s (WHO) annual air quality guideline value. According to WHO, around 7 million people die annually from air pollution, with 4.2 million deaths due to ambient air pollution. The effects of smog are widespread and severe. Health hazards include respiratory problems, eye irritation, cardiovascular diseases, and even lung cancer. Environmental impacts affect plant growth, reduce visibility, and contribute to climate change. The economic impact is substantial, with health … Continue reading The Smog Plague in Pakistan: Facts and Fixes
