Health effects of PM2.5 exposure — Styria

The Federal Environment Agency has investigated the reduction of life expectancy due to PM2.5 exposure to fine dust in Styria. The analyses are based on exposure-response relationships derived, inter alia, from the WHO. For the years 2005 to 2008, PM2.5 loads were estimated on the basis of PM10 in Styria. The results show that life expectancy is expected to be reduced by an average of eleven months in Graz. The average reduction in life expectancy due to particulate matter pollution is estimated at seven months for Styria. Compared to the 2005 estimates, there is a significant improvement. The reasons for this are the low pollution levels of recent years and a more precise spatial allocation in the calculation model.

联邦环境署针对施蒂利亚州因细颗粒物PM2.5暴露引发的预期寿命损失开展了调研。本次分析所依托的暴露-响应关系，除其他来源外，源自世界卫生组织（WHO）。2005年至2008年间，研究人员基于施蒂利亚州的PM10数据估算了当地的PM2.5负荷。结果显示，格拉茨市居民的预期寿命平均缩短11个月；整个施蒂利亚州因颗粒物污染导致的预期寿命平均损失约为7个月。相较于2005年的估算结果，本次研究成果已有显著改善，其原因在于近年污染水平有所降低，同时计算模型中的空间分配精度得到提升。
