Abstract:
Objective:To examine the correlation between atmospheric PM2.5 and emergency call for respiratory diseases.
Methods:The daily emergency call for respiratory and cardio-cerebrovascular diseases was collected from Hangzhou Emergency Medical Center from 2018 to 2020, and meteorological and atmospheric pollutant data were collected from Hangzhou Municipal Center for Ecological and Environmental Monitoring during the same period, including daily mean air temperature, daily mean relative humidity, PM2.5, PM10 and SO2 levels. The correlation between atmospheric PM2.5 and emergency call for respiratory and cardio-cerebrovascular diseases was examined using a generalized additive model, and the risk of emergency call was predicted using excessive risk (ER) and its 95%CI.
Results:The daily mean emergency call was 14 (interquartile range, 12) cases for respiratory diseases and 20 (interquartile range, 7) cases for cardio-cerebrovascular diseases in Hangzhou City from 2018 to 2020, and the daily mean PM2.5 mass concentration was 29.77 (interquartile range, 21.32) μg/m3. Cumulative exposure to PM2.5 for 5 or 6 d caused the largest effect on the emergency call for respiratory diseases, and an increase in PM2.5 by 10 μg/m3 led to a 1.93% (95%CI: 0.76%-3.11%) rise in the emergency call for respiratory diseases. Cumulative exposure to PM2.5 for 4 d caused the largest effect on the emergency call for cardio-cerebrovascular diseases, and an increase in PM2.5 by 10 μg/m3 led to a 1.88% (95%CI: 0.80%-2.97%) rise in the emergency call for cardio-cerebrovascular diseases. Cumulative exposure to PM2.5 for 7 d caused the largest effect on the emergency call for respiratory diseases among residents aged 60 years and older, and an increase in PM2.5 by 10 μg/m3 led to a 4.37% (95%CI: 2.70%-6.06%) rise in the emergency call for respiratory diseases. Cumulative exposure to PM2.5 for 4 d caused the largest effect on the emergency call for cardio-cerebrovascular diseases among residents aged 60 years and older, and an increase in PM2.5 by 10 μg/m3 led to a 2.44% (95%CI: 0.97%-3.52%) rise in the emergency call for cardio-cerebrovascular diseases. However, exposure to PM2.5 had no marked effects on emergency call for respiratory or cardio-cerebrovascular diseases among residents aged <60 years.
Conclusions:Elevated atmospheric PM2.5 mass concentration may lead to an increase in the daily emergency calls for respiratory and cardio-cerebrovascular diseases, notably among residents aged 60 years and older.
