Health and Economic Benefits of Complying With the World Health Organization Air Quality Guidelines for Particulate Matter in Nine Major Latin American Cities.

ABSTRACT:

Objectives

This study aims to estimate the short-term preventable mortality and associated economic costs of complying with the World Health Organization (WHO) air quality guidelines (AQGs) limit values for PM₁₀ and PM_2.5 in nine major Latin American cities.

Methods

We estimated city-specific PM-mortality associations using time-series regression models and calculated the attributable mortality fraction. Next, we used the value of statistical life to calculate the economic benefits of complying with the WHO AQGs limit values.

Results

In most cities, PM concentrations exceeded the WHO AQGs limit values more than 90% of the days. PM₁₀ was found to be associated with an average excess mortality of 1.88% with concentrations above WHO AQGs
