Kathmandu, February 16 – The Kathmandu Valley is grappling with a significant rise in air pollution, posing severe health risks to its residents. Over the past week, the Air Quality Index (AQI) has consistently crossed unhealthy thresholds, peaking at 169 on Saturday night.
The data shows a troubling trend, with AQI levels recorded at 164 on Magh 27 and 28, 159 on Magh 29, 160 on Magh 30, 163 on Falgun 1, and 169 on Falgun 2. According to health experts, an AQI above 150 is deemed harmful, particularly for individuals with respiratory conditions and the elderly, while levels above 200 pose risks to all age groups.
Adding to the concern, the level of PM2.5 (particulate matter) in Kathmandu’s air was measured at 78 micrograms per cubic meter on Saturday evening. This is 15.6 times higher than the World Health Organization’s (WHO) safe limit of 5 micrograms per cubic meter.
“Prolonged exposure to such high pollution levels can lead to respiratory illnesses, cardiovascular issues, and other severe health complications,” warned a public health expert.
The situation is exacerbated by dry weather conditions, as the lack of rainfall has prevented the dispersion of pollutants. Environmental scientists have expressed concerns that pollution levels may rise further if the current weather pattern persists.
Global Context
Kathmandu is not alone in its air quality crisis. Other cities facing hazardous pollution levels include Wuhan and Shanghai in China, Yangon in Myanmar, Kolkata and New Delhi in India, and Dhaka in Bangladesh. These cities, like Kathmandu, are grappling with the adverse impacts of rapid urbanization and industrialization.
The Call for Action
This alarming data highlights the urgent need for effective air pollution control measures. Experts recommend prioritizing tree plantation, reducing vehicular emissions, and enforcing strict industrial pollution controls. Immediate steps are also needed to enhance public awareness about air pollution and its health impacts.
As the capital city battles this environmental challenge, the government and stakeholders must act decisively to safeguard public health and ensure a cleaner, safer environment for future generations.
