ECONOMIC IMPACT OF AIR POLLUTION PM2.5 ON RESPIRATORY ILLNESS: A CASE STUDY OF ABBOTTABAD

Abstract

This study quantifies and evaluates the impact of (PM_2.5) on human health, shows its association with respiratory disorders in Abbottabad city. Using environmental, economic and statistical tools, the study linked elevated ????????_2.5 concentrations with increase in diseases. A mixed sampling design was used: stratified by location, purposive by exposure level and convenience by accessibility. The selected study areas included low-pollution zones such as Jinnahbad, Kaghan Colony and Habibullah Colony, along with high-pollution zones including Karakoram highway which make this area more congested with local, commercial and highway traffic. Result of the study showed varying in PM_2.5 levels beyond the safe limits set by World Health Organization. The estimated MWTP per household, derived from the probability of illness, medical expenditures and related costs, averaged USD34.05 annually. The annual Cost of Illness USD31.63 and Avertive Expenditures USD 5.45 were calculated to estimate the total economic burden on households. A strong, statistically significant positive correlation was found between PM_2.5 levels and the prevalence of respiratory disorders. Policymakers are urged to prioritize mitigation in highly polluted areas through targeted interventions that safeguard community health.
