《AJAE》| Lai et al：空气污染与认知功能：来自中国秸秆焚烧的证据

摘要：本研究通过将家庭健康调查与来自火灾活动遥感数据的 PM2.5 排放联系起来，研究了秸秆燃烧造成的空气污染对中国人认知健康的影响。识别策略利用了由于外源风向引起的空气污染物的空间分散。结果表明，上风向秸秆燃烧产生的 PM2.5 排放对 55 岁及以上受访者的认知功能有负面影响，但下风向火灾产生的 PM2.5 排放没有。这种影响是暂时的，是由认知测试当天同时排放的 PM2.5 造成的。我们的研究结果证明了空气污染与认知能力下降之间的联系，并表明通过这种联系，气候变化可能会增加野火风险，从而导致额外的健康成本。

Abstract: This study examines theimpact of air pollution from straw burning on human cognitive health in Chinaby linking household health surveys with PM2.5 emissions derived from remotesensing data on fire activity. The identification strategy leverages thespatial dispersion of air pollutants due to exogenous wind directions. Theresults indicate that PM2.5 emissions from upwind straw burning have a negativeimpact on cognitive functions of respondents aged 55 and above, but PM2.5emissions from downwind fires do not. The impact is transitory and caused bycontemporaneous PM2.5 emissions on the day of cognitive testing. Our findingsdemonstrate a link from air pollution to cognitive declines and suggest thatthrough this link, climate change could result in additional health costs byincreasing the risk of wildfires.
