Research press release





今回、Qiang Zhangたちの研究チームは、2007年のPM2.5汚染に関連した全世界の若年死345万例を評価して、その約12%が死亡地以外の地域で排出された汚染物質に関連し、約22%が生産地と消費地の異なる物品・サービスに関連していたことを明らかにした。この新知見は、国際貿易に伴うPM2.5汚染の健康影響の方が、大気を経由した汚染物質の長距離輸送に伴うPM2.5汚染の健康影響よりも甚大であることを示唆している。

More than one million premature deaths in 2007 have been related to fine particulate matter pollution as a result of international trade and the transport of pollution through the atmosphere, according to a global analysis of air quality and premature mortality presented this week in Nature.

Fine particulate matter (PM2.5) is thought to account for more than 90% of premature deaths from outdoor air pollution around the world. Although pollutants from local sources, such as industry and transportation, are thought to influence the susceptibility of nearby populations to conditions such as heart disease and lung cancer, the effects of pollution embodied in international trade on global health is not well understood.

Qiang Zhang and colleagues assessed 3.45 million global premature deaths in 2007 related to PM2.5 pollution and found that approximately 12 per cent of these deaths were related to pollutants emitted in a region of the world other than that in which the death occurred, while about 22 per cent were associated with goods and services produced in one region but consumed in another. The findings suggest that the health impacts of fine particulate matter pollution associated with international trade are greater than those associated with long-distance atmospheric pollutant transport.

Authors Qiang Zhang and Steven Davis will discuss their research. This will be followed by a Q&A session.
