Abstract:
Objectives: Excess mortality associated with long-term exposure to fine particulate matter (PM 〈 sub 〉 2.5 〈 /sub 〉 ) has been documented. However, research on the disease burden following short-term exposure is scarce. We investigated the cause-specific mortality burden of short-term exposure to PM 〈 sub 〉 2.5 〈 /sub 〉 by considering the potential non-linear concentration–response relationship in Korea.Methods: Daily cause-specific mortality rates and PM 〈 sub 〉 2.5 〈 /sub 〉 exposure levels from 2010 to 2019 were collected for 8 Korean cities and 9 provinces. A generalized additive mixed model was employed to estimate the non-linear relationship between PM 〈 sub 〉 2.5 〈 /sub 〉 exposure and cause-specific mortality levels. We assumed no detrimental health effects of PM 〈 sub 〉 2.5 〈 /sub 〉 concentrations below 15 μg/m 〈 sup 〉 3 〈 /sup 〉 . Overall deaths attributable to short-term PM 〈 sub 〉 2.5 〈 /sub 〉 exposure were estimated by summing the daily numbers of excess deaths associated with ambient PM 〈 sub 〉 2.5 〈 /sub 〉 exposure.Results: Of the 2 749 704 recorded deaths, 2 453 686 (89.2%) were non-accidental, 591 267 (21.5%) were cardiovascular, and 141 066 (5.1%) were respiratory in nature. A non-linear relationship was observed between all-cause mortality and exposure to PM 〈 sub 〉 2.5 〈 /sub 〉 at lag0, whereas linear associations were evident for cause-specific mortalities. Overall, 10 814 all-cause, 7855 non-accidental, 1642 cardiovascular, and 708 respiratory deaths were attributed to short-term exposure to PM 〈 sub 〉 2.5 〈 /sub 〉 . The estimated number of all-cause excess deaths due to short-term PM 〈 sub 〉 2.5 〈 /sub 〉 exposure in 2019 was 1039 (95% confidence interval, 604 to 1472).Conclusions: Our findings indicate an association between short-term PM 〈 sub 〉 2.5 〈 /sub 〉 exposure and various mortality rates (all-cause, non-accidental, cardiovascular, and respiratory) in Korea over the period from 2010 to 2019. Consequently, action plans should be developed to reduce deaths attributable to short-term exposure to PM 〈 sub 〉 2.5 〈 /sub 〉 .
