Ambient PM 2.5 and O 3 pollution and health impacts in Iranian megacity

The main objectives of this study were to (i) assess variation within fine particles (PM ) and tropospheric ozone (O ) time series in Khorramabad (Iran) between 2019 (before) and 2020 (during COVID-19 pandemic); (ii) assess relationship between PM and O , the PM /O ratio, and energy consumption; and...

Description
Summary:The main objectives of this study were to (i) assess variation within fine particles (PM ) and tropospheric ozone (O ) time series in Khorramabad (Iran) between 2019 (before) and 2020 (during COVID-19 pandemic); (ii) assess relationship between PM and O , the PM /O ratio, and energy consumption; and (iii) estimate the health effects of exposure to ambient PM and O . From hourly PM and O concentrations, we applied both linear-log and integrated exposure-response functions, city-specific relative risk, and baseline incidence values to estimate the health effects over time. A significant correlation was found between PM and O (  =-0.46 in 2019,  =-0.55 in 2020,
