Transregional transport plays an important role in air pollution. This study investigated the impact of transregional transport on particle pollution in Shanghai from 2013 to 2017. A conditional potential source contribution function (CPSCF) method with high time resolution (1 h) PM and PM data was used to quantify the contribution of transregional transport. The corresponding health impact was also assessed. The average annual contribution of transregional transport to PM (PM) and PM (PM) was 22 and 30 μg/m, 18 and 24 μg/m, 19 and 24 μg/m, 14 and 19 μg/m, and 14 and 19 μg/m, for 2013 to 2017, respectively, thus accounting for 31-37% of total PM and PM. As PM is a dominant component of PM, the health effects related to PM were assessed to avoid double counting. The number of annual deaths associated with PM in Shanghai during the study period ranged from 636 (95% confidence intervals: 350, 936) to 1039 (573, 1530), among which cardiovascular disease and respiratory disease accounted for 62.8-67.6% and 16.6-19.5% of mortality, respectively. PM-related deaths accounted for 5.3-8.2‰ of the total mortality in Shanghai during the study period. Between 9764 (9251, 10,277) and 12,190 (11,549, 12,830) cases of all-cause hospital admissions were attributable to PM in Shanghai in one year, among which cardiovascular disease and respiratory disease hospital admissions accounted for 15.9-20.0% and 7.9-9.2%, respectively. Internal medicine and pediatrics outpatient visits related to PM ranged from 70,684 (39,009, 100,829) to 97,380 (53,788, 138,793) cases and 23,185 (8302, 37,173) to 32,702 (11,726, 52,361) cases, respectively. The current work provides scientific evidence of the impact of transregional transport on air pollution and its health burden in Shanghai.
区域间传输在空气污染中起着重要作用。本研究调查了 2013 年至 2017 年期间区域间传输对上海颗粒物污染的影响。使用具有高时间分辨率（1 小时）PM 和 PM 数据的条件潜在源贡献函数（CPSCF）方法来量化区域间传输的贡献。还评估了相应的健康影响。2013 年至 2017 年，区域间传输对 PM（PM）和 PM（PM）的平均年贡献分别为 22 和 30μg/m、18 和 24μg/m、19 和 24μg/m、14 和 19μg/m、14 和 19μg/m，占 PM 和 PM 的 31-37%。由于 PM 是 PM 的主要成分，因此评估了与 PM 相关的健康影响，以避免重复计算。在研究期间，上海每年与 PM 相关的死亡人数范围为 636（95%置信区间：350，936）至 1039（573，1530），其中心血管疾病和呼吸系统疾病分别占死亡人数的 62.8-67.6%和 16.6-19.5%。PM 相关死亡人数占研究期间上海总死亡人数的 5.3-8.2‰。在上海，每年归因于 PM 的所有原因住院病例数为 9764（9251，10000，10277）至 12190（11549，12000，12830）例，其中心血管疾病和呼吸系统疾病住院病例数分别占 15.9-20.0%和 7.9-9.2%。与 PM 相关的内科和儿科门诊就诊人数范围为 70684（39009，100829）至 97380（53788，138793）例和 23185（8302，37173）至 32702（11726，52361）例。目前的工作为区域间传输对上海空气污染及其健康负担的影响提供了科学依据。
