Abstract:
Objectives: The study estimated the environmental burden of disease (EBD) attributable to a long-term exposure of the population to nitrogen dioxide (NO2) and fine particulate matter (PM2.5) emissions from hard coal- and lignite-fired power plants in Germany for the year 2015. Methods: The contribution of coal-fired power plants to the total air pollutant concentration was modelled using a chemical transport model and then combined with population data to assess the corresponding population exposure. We calculated years of life lost (YLL), years of life with disability, or disability-adjusted life years for different health outcomes with a strong evidence for an association with the exposure. Results: The burden of disease from PM2.5 emissions from lignite is 1.2 times higher than that from hard coal emissions (7,866 YLL compared to 6,412 YLL). NO2 emissions from lignite, cause a burden of disease 2.3 times higher than hard coal NO2-emission (13,537 YLL compared to 5,906 YLL). The EBD for both pollutants is dominated by diseases of the cardiovascular system. Conclusion: Abandoning energy generation by coal-fired power plants would lower the burden of disease in Germany.
摘要:
目标:该研究估计了由于人口长期暴露于德国硬煤和褐煤发电厂的二氧化氮(NO2)和细颗粒物(PM2.5)排放而造成的环境负担(EBD)2015年。方法:使用化学迁移模型对燃煤电厂对总空气污染物浓度的贡献进行建模,然后将其与人口数据相结合以评估相应的人口暴露。我们计算了生命损失的年份(YLL),多年的残疾生活,或不同健康结局的残疾调整寿命年,有强有力的证据表明与暴露相关。结果:褐煤PM2.5排放的疾病负担是硬煤排放的1.2倍(7,866YLL比6,412YLL)。褐煤的NO2排放,造成的疾病负担是硬煤NO2排放的2.3倍(13,537YLL与5,906YLL相比)。这两种污染物的EBD主要是心血管系统疾病。结论:放弃燃煤电厂发电将降低德国的疾病负担。
