Air pollution in Kathmandu Valley has reached alarming levels, with residents reporting difficulty breathing and eye irritation due to the haze of smog that has settled over the city.

According to data from the Department of Environment, air quality in the valley has deteriorated to "hazardous" levels, with levels of PM2.5 - tiny particles that can penetrate deep into the lungs - far exceeding the recommended limits.

The main contributors to the pollution are vehicle emissions, dust from construction sites, and the burning of biomass for cooking and heating.

The situation has been exacerbated by a lack of action from the government and inadequate public transportation options, leading to a growing number of private vehicles on the roads.

Residents are calling on the government to take urgent action to address the crisis, including implementing stricter regulations on vehicle emissions and construction sites, promoting the use of public transportation, and encouraging the use of cleaner fuels for cooking and heating.

Experts warn that if nothing is done, the long-term health consequences could be severe, with increased risk of respiratory diseases and premature death.

The situation in Kathmandu Valley is not unique, as many cities in developing countries are facing similar challenges due to rapid urbanization and industrialization. However, urgent action is needed to protect the health and well-being of the city's residents.
