Mar 08, Kathmandu - Kathmandu Valley is experiencing a surge in air pollution as recent days have seen an increase in smog due to changing weather conditions. The prolonged lack of rainfall and stagnant air are contributing factors, according to environmental officials.

Gyanraj Subedi, Director General of the Department of Environment, explained that the weather has become hazy due to extended dry periods and minimal wind movement. "There hasn't been rain for a long time, and the air isn't circulating properly. This has led to increased smog in recent days," he stated. However, he added that compared to last year, pollution levels are somewhat lower, and unless forest fires break out, the pollution is unlikely to escalate significantly.

As of midday today, the Air Quality Index (AQI) in Kathmandu Valley has reached 186, categorizing it as the fourth most polluted city in the world, according to environmental expert Bhushan Tulaadhar. He emphasized the importance of proactive measures such as proper waste management, fire prevention, vehicle emission testing, and strict enforcement of pollution control standards to combat the rising pollution levels.

The AQI scale ranges from 0 to 500, with 0-50 considered 'Good,' 51-100 'Moderate,' 101-150 'Unhealthy for Sensitive Groups,' 151-200 'Unhealthy for All,' 201-300 'Very Unhealthy,' and above 300 'Hazardous.' Director General Subedi urged residents, especially those with respiratory and heart conditions, to exercise caution as the current AQI indicates a 'Unhealthy' level, which can adversely affect vulnerable populations.
