Abstract

This study evaluated the prospective damage costs of PM2.5 inhalation. We performed a health risk assessment based on an exposure-response function to estimate the annual population risk in the Seoul metropolitan city, Korea. Also, we estimated a willingness-to-pay (WTP) amount for reducing the mortality rate in order to evaluate a statistical life value.We combined the annual population risk and the value-of-statistical-life to calculate the damage cost estimate. In the health risk assessment, we applied the PM2.5 relative risk to evaluate the annual population risk. We targeted an exposure population of 5,401,369 persons who were over the age of 30.Using a Monte-Carlo simulation for uncertainty analysis, we estimated that the population risk of PM2.5 inhalation during a year in Seoul is 2181 premature deaths for acute exposure and 18,510 premature deaths for chronic exposure. The monthly average WTP for 5/1000 mortality reduction over ten years is $20.20 USD (95% C.I: $16.60-24.50) and the implied value-of-statistical-life (VSL) is $485,000 USD (95% C.I: $398,000-588,000). The damage cost estimate due to risk from PM2.5 inhalation in Seoul is about $1057 million USD per year for acute exposure, and $8972 million USD per year for chronic exposure.It is important to note that this cost estimate does not reflect all health damage cost estimates in this urban area. This recommendation is a model for evaluating a mortality risk reduction and as such we must re-evaluate an integrated application of morbidity risk.
