» PNAS新文研究結(jié)果, 用期望壽命為冬季供暖買單

淮河南北期望壽命差5.5年。PNAS發(fā)表的最新研究表明，因為淮河南北供暖政策的不同，導致過去20年間，淮河以北居民期望壽命比淮河以南短大概5.5年。而其根本原因是煤炭燃燒導致的空氣懸浮顆粒多少不同所致。如何平衡發(fā)展經(jīng)濟、環(huán)境保護和公共健康之間的關系真是迫在眉睫的任務了。
供暖會加重空氣污染導致期望壽命降低，但是不供暖的話寒冷會導致多少期望壽命降低就沒法弄到數(shù)據(jù)了
This paper's findings suggest that an arbitrary Chinese policy that greatly increases total suspended particulates (TSPs) air pollution is causing the 500 million residents of Northern China to lose more than 2.5 billion life years of life expectancy. The quasi-experimental empirical approach is based on China’s Huai River policy, which provided free winter heating via the provision of coal for boilers in cities north of the Huai River but denied heat to the south. Using a regression discontinuity design based on distance from the Huai River, we find that ambient concentrations of TSPs are about 184 μg/m3 or 55% higher in the north. Further, the results indicate that life expectancies are about 5.5 y (95% CI: 0.8, 10.2) lower in the north owing to an increased incidence of cardiorespiratory mortality. More generally, the analysis suggests that long-term exposure to an additional 100 μg/m3 of TSPs is associated with a reduction in life expectancy at birth of about 3.0 y (95% CI: 0.4, 5.6).

美國科學院院報真是啥玩意兒都寫。。。
難怪影響因子上不去

貌似國外很多地方燒壁爐吧，那玩意污染也不小。
