ABSTRACT: Background
China began to carry out fine particulate matter (PM2.5) monitoring in 2013 and the amount of related research is low, especially in areas with lighter air pollution. This study aims to explore the association between PM2.5 and cardiovascular disease (CVD), ischemic heart disease (IHD) and cerebral vascular disease (EVD) mortality in areas with lighter air pollution.Methods
Data on resident mortality, air pollution and meteorology in Shenzhen during 2013?2015 were collected and analyzed using semi-parametric generalized additive models (GAM) with Poisson distribution of time series analysis.Results
Six pollutants were measured at seven air quality monitoring sites, including PM2.5, PM10, SO?, NO?, CO and O?. The PM2.5 daily average concentration was 35.0 ± 21.9 ?g/m³; the daily average concentration range was from 7.1 ?g/m³ to 137.1 ?g/m³. PM2.5 concentration had significant effects on CVD, IHD and EVD mortality. While PM2.5 concentration of lag5 and lag02 rose by 10 ?g/m³, the excess risk (ER) of CVD mortality were 1.50% (95% CI: 0.51?2.50%) and 2.09% (95% CI: 0.79?3.41%), respectively. While PM2.5 concentration of lag2 and lag02 rose by 10 ?g/m³, the ER of IHD mortality were 2.87% (95% CI: 0.71?5.07%) and 3.86% (95% CI: 1.17?6.63%), respectively. While PM2.5 concentration of lag4 and lag04 rose by 10 ?g/m³, the ER of EVD mortality were 2.09% (95% CI: 2.28?3.92%) and 3.08% (95% CI: 0.68?5.53%), respectively.Conclusions
PM2.5 increased CVD mortality. The government needs to strengthen the governance of air pollution in areas with a slight pollution.
