Air pollution has been estimated to be one of the leading environmental health risks in Finland. National health impact estimates existing to date have focused on particles (PM) and ozone (O₃). In this work, we quantify the impacts of particles, ozone, and nitrogen dioxide (NO₂) in 2015, and analyze the related uncertainties. The exposures were estimated with a high spatial resolution chemical transport model, and adjusted to observed concentrations. We calculated the health impacts according to Word Health Organization (WHO) working group recommendations. According to our results, ambient air pollution caused a burden of 34,800 disability-adjusted life years (DALY). Fine particles were the main contributor (74%) to the disease burden, which is in line with the earlier studies. The attributable burden was dominated by mortality (32,900 years of life lost (YLL); 95%). Impacts differed between population age groups. The burden was clearly higher in the adult population over 30 years (98%), due to the dominant role of mortality impacts. Uncertainties due to the concentration-response functions were larger than those related to exposures.
空气污染被估计为芬兰主要的环境健康风险之一。迄今为止,国家健康影响评估主要集中在颗粒物 (PM) 和臭氧 (O3)。在这项工作中,我们量化了 2015 年颗粒物、臭氧和二氧化氮 (NO2) 的影响,并分析了相关的不确定性。暴露量是用高空间分辨率的化学输送模型估算的,并根据观测到的浓度进行了调整。我们根据世界卫生组织 (WHO) 工作组的建议计算了健康影响。根据我们的结果,环境空气污染造成 34800 个伤残调整生命年 (DALY) 的负担。细颗粒物是疾病负担的主要贡献者 (74%),这与早期的研究一致。归因于疾病负担的主要是死亡 (32900 年生命损失 (YLL);95%)。各年龄段人群的影响不同。由于死亡影响的主导作用,30 岁以上的成年人口的负担明显更高 (98%)。由于浓度-反应函数引起的不确定性大于暴露引起的不确定性。
