Acute effects of air pollutants on respiratory diseases in Fengxian District, Shanghai

  • Objective To assess the acute effects of air pollutants on respiratory diseases in Fengxian District of Shanghai.

    Methods Data on outpatient or emergency department visits due to respiratory diseases were collected from all levels of public hospitals in Fengxian District, respiratory disease deaths of registered populations from Fengxian District Center for Disease Control and Prevention, meteorological factors from Fengxian District Meteorological Bureau, and ambient air pollutants from local environmental monitoring stations from 2013 to 2016, respectively. Generalized additive model was applied to analyze the relationship of air pollutants with the number of daily outpatient and emergency visits for respiratory diseases and the number of daily deaths.

    Results The influences of various air pollutants on the amount of respiratory outpatient and emergency visits were varied:0.37%, 0.24%, 0.41%, 0.54%, 0.47%, 0.43%, and 0.36% increase of the visits on lag day 0-6 for per 10 μg/m3 increase of PM10, respectively (Ps < 0.01); 1.87%, 1.74%, 1.97%, 2.15%, 2.28%, 2.35%, and 1.92% increase on lag day 0-6 for per 10μg/m3 increase of SO2, respectively (Ps < 0.01); 2.51%, 1.91%, 1.74%, 1.85%, 1.98%, 1.77%, and 1.57% increase on lag day 0-6 for per 10 μg/m3 increase of NO2, respectively (Ps < 0.01); 0.35% decrease on lag day 1 for per 10 μg/m3 increase of PM2.5 (P < 0.01); 5.81% and 4.03% decrease on lag day 2-3 for per 10 μg/m3 increase of CO (P < 0.01); 0.37% and 0.32% increase on lag day 3 and lag day 5 for per 10 μg/m3 increase of O3, respectively (P < 0.01). The influences of selected air pollutants on the deaths from respiratory diseases were also different:1.29% increase of deaths on lag day 3 for per 10 μg/m3 increase of PM10 (P < 0.01); 4.94% and 4.52% increase on lag day 3-4 for per 10μg/m3 increase of SO2, respectively (P < 0.01); 4.82%, 3.78%, and 3.98% increase on lag day 0, 2, and 3 for per 10μg/m3 increase of NO2, respectively (Ps < 0.01); 3.12% increase on lag day 1 for per 10μg/m3 increase of O3 (P < 0.01); while the changes of PM2.5 and CO concentrations were not associated with the deaths on lag day 0-6. The results of two-pollutant model showed increased respiratory outpatient and emergency visits associated with per 10 μg/m3 increase of PM10, SO2, PM2.5, and O3 after adjusting for NO2 (P < 0.01).

    Conclusion PM10, SO2, PM2.5, and O3 can affect the respiratory outpatient and emergency visits in Fengxian District of Shanghai and deaths of local registered residents.
