Zusammenfassung:Tropospheric ozone is the second most important atmospheric pollutant after particulate matter with respect to its impact on human health and is increasing of its concentrations globally. The main objective of this study was to assess of health effects attributable to ground-level ozone (O3) in Kermanshah, Iran using one-hour O3 concentrations measured between March 2014 and March 2015. The AirQ program was applied for estimation of the numbers of cardiovascular mortality (CM), respiratory mortality (RM), and hospital admissions for chronic obstructive pulmonary disease (HA-COPD) using relative risk (RR) and baseline incidence (BI) as defined by the World Health Organization (WHO). The largest percentage of person-days for different O3 concentrations was in the concentration range of 30–39µg/m3. The health modeling results suggested that ~2% (95% CI: 0–2.9%) of cardiovascular mortality, 5.9% (95% CI: 2.3–9.4) of respiratory mortality, and 4.1% (CI: 2.5–6.1%) of the HA-COPD were attributed to O3 concentrations higher than 10µg/m3. For each 10µg/m3 increase in O3 concentration, the risk of cardiovascular mortality, respiratory mortality, and HA-COPD increased by 0.40%, 1.25%, and 0.86%, respectively. Furthermore, 88.8% of health effects occurred on days with O3 level less than 100µg/m3. Thus, action is needed to reduce the emissions of O3 precursors especially transport and energy production in Kermanshah. •The approach proposed by the WHO was used to estimate health effects of ground level ozone.•Two percent of CM and 5.9 percent of RM in Kermanshah were attributed to tropospheric ozone.•HA-COPD attributed to O3 was estimated around 4.1 percent.•Low emission fuel for industry and transportation is recommended to diminish precursors of ozone.
