Abstract:
Objective:To evaluate the impact of fine particulate matter ( PM2.5 ) on respiratory diseases and symptoms of community residents in Chun’an County, so as to provide the basis for air pollution treatment strategies.
Methods:Using the cluster random sampling method, the permanent residents in Qiandaohu Town of Chun’an County were investigated from 2017 to 2018. The demographic information, respiratory diseases and symptoms were collected by using Surveillance Plan for the Impact of Air Pollution ( Haze ) on health ( 2016 Edition ). The air pollutants and meteorological data were collected through Qiandaohu station of Hangzhou Ecology and Environment Monitoring Center and Hangzhou Meteorological Information Center. The effects of PM2.5 on respiratory diseases and symptoms of residents were analyzed with generalized estimating equation.
Results:Totally 1 181 people aged 6 months to 95 years were recruited, including 557 ( 47.16% ) males and 624 ( 52.84% ) females. Acute nasopharyngitis (common cold) and tracheitis/tonsillitis occurred most frequently, with 203 cases, accounting for 3.44%. The median of daily average concentration of PM2.5 was 24 μg/m3, with the standard exceeding rate of 2.80%. The results showed that PM2.5 increased the risk of acute nasopharyngitis ( common cold ), tracheitis/tonsillitis, cough, expectoration, runny nose, sore throat and nasal congestion ( lag 3 days, OR: 1.015-1.022, 95%CI: 1.001-1.037 ); the effect of PM2.5+PM10 ( OR: 1.020-1.040, 95%CI: 1.006-1.070 ) and PM2.5+O3 ( OR: 1.017-1.024, 95%CI: 1.005-1.035 ) was greater than that of PM2.5 alone on respiratory diseases and symptoms.
Conclusion:Atmospheric PM2.5 exposure in Chun’an County increases the risk of respiratory diseases and symptoms among community residents.
