摘要：Objective:This study aims to evaluate the relationship between PM2.5 concentration and daily mortality rate from cardiovascular and cerebrovascular diseases(CCVD)in cold regions of northern China,as well as to identify the primary sources of PM2.5.Methods:A time series analysis model was used to calculate the exposure-response relationship between PM2.5 and CCVD mortality in Harbin.Positive matrix factorization(PMF)was employed to analyze the sources of PM2.5.Results:After adjusting for multiple pollutant combinations,the maximum excess risk of cardio-cerebrovascular death on the day of PM2.5 exposure was 0.42%(95%CI:0.15%-0.70%).Stratification by gender and age revealed that the elderly individuals and men were particularly susceptible to PM2.5 exposure.The source analysis identified seven major pollution sources contributing to PM2.5 in Harbin.Conclusion:Our findings strengthen the evidence that PM2.5 is an independent risk factor for daily CCVD mortality,identify vulnerable populations that require special attention,and pinpoint the primary sources of PM2.5 in Harbin.These findings provide reference points for effectively reducing the health risks associated with PM2.5 exposure.
