Abstract:
Objectives To estimate the long-term health benefits of residents in Jinan city during the National Air Pollution Control Action from 2013 to 2017.
Methods The daily average concentration of PM2.5 in Jinan city during 2013-2017 and the monitoring data of death causes in 2013 and 2017 were collected. The authors used an Interior and Exterior Risk model (IER) of attributable environmental particulate matter exposure to calculate the population attributable fraction(PAF) of cardiovascular disease, ischemic heart disease, stroke, lung cancer and chronic obstructive pulmonary disease. Then the authors estimated the long-term health benefits brought by decreased PM2.5 during 2013-2017.
Results The annual average concentration of PM2.5 in Jinan city and its districts and counties decreased year by year in 2013 to 2017.The overall reduction was 41.8%, but it was still characterized by high concentrations in the heating season. The PAFs (2013/2017) of cardiovascular disease, ischemic heart disease, stroke, lung cancer, and chronic obstructive pulmonary disease in Jinan city in were 49.17%/30.61%, 83.85%/62.64%, 73.03%/50.72%, 95.71%/81.73% and 79.20%/57.17%, respectively. The population deaths would be reduced by 3 920, 2 236, 1 437, 357, and 351, respectively if the concentration of PM2.5 in 2013 decreased to the level of 2017.
Conclusions Under implementation of the national air pollution control action in 2013-2017, the atmospheric concentration of PM2.5 in Jinan City declined obviously, and the deaths attributed to the five types of diseases decreased significantly. It was recommended to continually actively promote the air pollution control action, and pay attention to environmental protection measures and exposure protection during the heating season.
