“…In contrast, we found that men were more susceptible to the effects of O 3 on respiratory mortality than women. A research carried out in Shenzhen also found the similar result [ 55 ], which could be explained by the fact that pneumonia and bronchitis were more commonly observed in men who had a smoking history and different occupational exposures, which may exacerbate the impact of O 3 on respiratory mortality [ 56 ].…”

Background In recent years, air pollution has become an imminent problem in China. Few studies have investigated the impact of air pollution on the mortality of the middle-aged and elderly people. Therefore, this study aims to evaluate the impact of PM2.5 (fine particulate matter) and O3 (ozone) on non-accidental mortality and respiratory mortality of the middle-aged and elderly people in Lishui District of Nanjing and provide the evidence for potential prevention and control measures of air pollution. Method Using daily mortality and atmospheric monitoring data from 2015 to 2019, we applied a generalized additive model with time-series analysis to evaluate the association of PM2.5 and O3 exposure with daily non-accidental mortality and respiratory mortality in Lishui District. Using the population attributable fractions to estimate the death burden caused by short-term exposure to O3 and PM2.5。. Result For every 10 μg/m3 increase in PM2.5, non-accidental mortality increased 0.94% with 95% confidence interval (CI) between 0.05 and 1.83%, and PM2.5 had a more profound impact on females than males. For every 10 μg/m3 increase in O3, respiratory mortality increased 1.35% (95% CI: 0.05, 2.66%) and O3 had a more profound impact on males than females. Compared with the single pollutant model, impact of the two-pollutant model on non-accidental mortality and respiratory mortality slightly decreased. In summer and winter as opposed to the other seasons, O3 had a more obvious impact on non-accidental mortality. The population attributable fractions of non-accidental mortality were 0.84% (95% CI:0.00, 1.63%) for PM2.5 and respiratory mortality were 0.14% (95% CI:0.01, 0.26%) for O3. For every 10 μg/m3 decrease in PM2.5, 122 (95% CI: 6, 237) non-accidental deaths could be avoided. For every 10 μg/m3 decrease in O3, 10 (95% CI: 1, 38) respiratory deaths could be avoided. Conclusion PM2.5 and O3 could significantly increase the risk of non-accidental and respiratory mortality in the middle-aged and elderly people in Lishui District of Nanjing. Exposed to air pollutants, men were more susceptible to O3 damage, and women were more susceptible to PM2.5 damage. Reduction of PM2.5 and O3 concentration in the air may have the potential to avoid considerable loss of lives.

“…Our research also found that ozone in spring and autumn had an effect on non-accidental mortality but was not statistically signi cant. Research conducted in many regions of East Asia found that O 3 levels in different seasons have varying degrees of impact on non-accidental mortality [51]. This may be due to geographical heterogeneity [52].…”

Background In recent years, air pollution has become an imminent problem in China. Few studies have investigated the impact of air pollution on the mortality of middle-aged and elderly people. Therefore, this study aims to evaluate the impact of PM2.5 and O3 on non-accidental mortality and respiratory mortality of the middle-aged and elderly in Lishui district of China and provide the scientific basis for the prevention and control measures of air pollution. Method: Using daily mortality and atmospheric monitoring data from 2015 to 2019, we applied a generalized additive model with time-series analysis to study the association of PM2.5 and O3 exposure with daily non-accidental mortality and respiratory mortality in Lishui district of China. Using attributable risk to estimate the death burden attributable to short-term exposure to O3 and PM2.5。 Result PM2.5 and O3 were associated with non-accidental and respiratory mortality. For every 10µg/m3 increased in PM2.5, non-accidental mortality increased 0.94% (95%CI: 0.05%-1.83%), and PM2.5 had a more significant impact on women. For every 10µg/m3 increased in O3, respiratory mortality increased 1.35% (95%CI: 0.05%-2.66%). and O3 had a more significant impact on men. Compared with single pollutant model, the impact of the two-pollutant model on non-accidental mortality and respiratory mortality slightly decreased. Besides, in summer and winter, O3 had a more obvious impact on non-accidental mortality. The Population Attributable Fractions of non-accidental mortality were 0.839% (95%CI:0.004–1.626%) for PM2.5 and the PAF of respiratory mortality were 0.135% (95%CI:0.005–0.263%) for O3. Conclusion PM2.5 and O3 could significantly increase the risk of non-accidental and respiratory mortality in middle-aged and elderly people in Lishui district, China. Exposing to air pollutants, men were more susceptible to O3 damage, and women were more susceptible to PM2.5 damage.

“…The lag effects of each indicator of nitrogen oxides on cardiovascular mortalities were also examined. Our previous work suggested that the effects of confounding air pollutants were stable with a 3-day lag (Wang et al, 2017;Wu et al, 2016;Zhang et al, 2016). Therefore, this study selected 3 days to analyse the lag effects.…”
