Kathmandu — Air pollution levels across the Kathmandu Valley have risen with the onset of the dry season, with several areas recording air quality levels that could pose health concerns, particularly for sensitive groups.
According to IQAir, Kathmandu recorded an Air Quality Index (AQI) of 114 on Friday, November 6, placing the city in the “unhealthy for sensitive groups” category.
Data from Kathmandu Metropolitan City’s air quality monitoring system also showed elevated pollution levels across several parts of the Valley on Thursday evening. AQI readings reached 158 in Lainchaur, 157 in Kamaladi, 156 in Dallu, 150 in Teku, 146 in Thapathali, 141 in Swayambhu and Balaju, 131 in Asan, and 127 in Chabahil.
The readings show considerable differences in pollution levels across the Valley, with some locations recording higher concentrations of airborne pollutants than others.
The beginning of the dry season can contribute to deteriorating air quality as reduced rainfall allows dust and fine particulate matter to remain suspended in the atmosphere for longer periods. Vehicle emissions, road dust, construction and other human activities can further contribute to pollution.
Children, older people and individuals with respiratory or other chronic health conditions are particularly vulnerable to the effects of polluted air. Limiting prolonged exposure to polluted outdoor air and taking appropriate precautions is advisable when pollution levels are elevated.
Kathmandu Metropolitan City has urged residents and concerned authorities to take measures to reduce activities that contribute to air pollution and help improve air quality across the Valley.
Meanwhile, neighbouring New Delhi has also recorded severe air pollution. The Jawaharlal Nehru Stadium recorded an AQI of 417 on Friday morning according to India’s official air-quality monitoring system, placing it in the severe category.
With the dry season continuing, regular monitoring of air quality and efforts to reduce major sources of pollution will remain important for protecting public health across Kathmandu Valley.
