本研究测定了2008年亚洲9个国家和地区（印度尼西亚、马来西亚、菲律宾、新加坡、泰国、中国大陆、中国台湾、韩国和日本）初级含碳气溶胶（黑碳：BC、有机碳：OC）的生产型排放、消费型排放和消费型健康影响。对于基于生产的排放量，根据亚洲国际投入产出表编制了2008年BC和OC的部门排放清单，其中包括家庭的直接排放量。然后，使用2008年AIIOT（最初是通过更新2000年的表格开发的）进行多区域环境投入产出分析，以计算每个国家和地区基于消费的排放量。在生产性排放中，中国的BC和OC排放量最高，共4520 Gg-C，占9个国家和地区排放总量的75%。就基于消费的排放而言，据估计中国的BC和OC排放总量为4，849千兆克，占所研究的亚洲总排放量的77%。我们还量化了一些国家和地区在其他国家和地区造成的排放量。此外，考虑到BC和OC在国家和地区之间的源受体关系，我们将其基于消费的排放量转换为每个国家和地区基于消费的健康影响。中国显示BC和OC对消费的健康影响最大，共计111 x 10（3）例过早死亡，其次是印度尼西亚，日本，泰国和韩国。中国占这些国家/地区基于消费的健康影响总和的87%，表明中国对亚洲基于消费的健康影响的贡献大于其基于消费的排放。通过阐明每个国家和地区对其他国家的健康影响以及这些影响来自哪个国家，我们证明了基于消费的健康影响的特征因国家和地区而异。我们还确定了健康状况的差异，
This study determined the production-based emissions, the consumption-based emissions, and the consumption-based health impact of primary carbonaceous aerosols (black carbon: BC, organic carbon: OC) in nine countries and regions in Asia (Indonesia, Malaysia, the Philippines, Singapore, Thailand, China, Taiwan, South Korea, and Japan) in 2008. For the production-based emissions, sectoral emissions inventory of BC and OC for the year of 2008 based on the Asian international input output tables (AIIOT) was compiled including direct emissions from households. Then, a multiregional environmental input output analysis with the 2008 AIIOT which was originally developed by updating the table of 2000 was applied for calculating the consumption-based emissions for each country and region. For the production-based emissions, China had the highest BC and OC emissions of 4520 Gg-C in total, which accounted for 75% of the total emissions in the nine countries and regions. For consumption-based emissions, China was estimated to have had a total of 4849 Gg-C of BC and OC emissions, which accounted for 77% of the total emissions in the Asia studied. We also quantified how much countries and regions induced emissions in other countries and regions. Furthermore, taking account of the source receptor relationships of BC and OC among the countries and regions, we converted their consumption-based emissions into the consumption-based health impact of each country and region. China showed the highest consumption-based health impact of BC and OC totaling 111 x 10(3) premature deaths, followed by Indonesia, Japan, Thailand and South Korea. China accounted for 87% of the sum total of the consumption-based health impacts of the countries/regions, indicating that China's contribution to consumption-based health impact in Asia was greater than its consumption-based emissions. By elucidating the health impacts that each country and region had on other countries and from which country the impacts were received, we demonstrated that the characteristics of the consumption-based health impact varied significantly by country and region. We also determined the difference in the health
