Abstract Based on the monitoring data of surface ozone in Shanghai in 2008, the daily maximum 8h(11:00~18:59)concentrations were averaged to represent the population-level ozone exposure level. All fixed residents living in Shanghai were the supposed affected population. In 2008, the annual average 8h maximum ozone concentration was 88μg/m3, and the ozone level in the central urban areas was lower than that in suburban areas (78μg/m3 versus 96μg/m3 respectively). It was estimated that 1892 (95% confidence intervals, 95%CI: 589~3540) premature deaths and 26049 (95%CI: 13371~38499) cases of hospital admission were attributable to surface ozone pollution in 2008 in Shanghai. The corresponding economic loss of ozone-related health impacts was roughly 3.24 (95%CI: 1.08~5.92) billion Yuan, 88.12% of which was due to premature deaths. Our analysis suggests that the surface ozone pollution has brought substantial health and economic loss to Shanghai residents.
