Short-term effect of exposure to air pollutants on cardiovascular and respiratory emergency visits in Tianjin
Objective To understand the short-term effect of air pollutants exposure on cardiovascular and respiratory emergency visits in Tianjin.Methods The daily data of Tianjin from 2020 to 2022 were collected,including the concentration of air pollutants,emergency visits and the meteorological data.The generalized linear model was used to explore the effect of air pollution on emergency visits.Results A total of 48 445 cases of the cardiovascular disease and 67 983 cases of the respiratory system emergency visits were collected during the study period.Each 10 μg/m3 increase in the concentration was associated with a higher incidence of cardiovascular emergency visits for PM2.5(0.39％,95％CI:0.01％-0.78％),NO2(1.18％,95％CI:0.41％-1.95％)and SO2(2.64％,95％CI:0.02％-5.23％),respectively,and no significant short-term effect of air pollutants exposure on emergency visits for respiratory diseases was observed.Conclusion The elevated levels of atmospheric PM2.5,NO2 and SO2 may increase the risk of cardiovascular emergency visits.
