Overview

Randomized trial estimates health and economic impacts of air pollution in Kathmandu Valley, suggesting urgent management strategies.

Key Points

  • The study aims to quantify the health and economic costs associated with ambient PM2.5 pollution in Kathmandu Valley.
  • Estimated mortality and DALYs attributable to PM2.5 exposure using environmental burden of disease framework.
  • Analyzed PM2.5 data from seven monitoring stations in the Kathmandu Valley.
  • Monetized health losses using a value-of-a-statistical-life-year approach.
  • Estimated 8,900 premature deaths annually due to long-term PM2.5 exposure (43% population-attributable fraction).
  • Total health burden quantified at 575,247 DALYs per year, including 340,247 years of life lost.
  • Annual economic cost attributed to health impacts was approximately USD 1.25 billion.
