Health effects of PM2.5 exposure - Styria

The Federal Environment Agency has investigated the reduction of life expectancy due to PM2.5 pollution in Styria. The analyses are based on exposure-response relationships derived from, among others, the WHO. For the years 2005 to 2008, the PM2.5 pollution was estimated on the basis of the PM10 pollution in Styria. The results show that life expectancy in Graz is expected to decrease by an average of eleven months. The average reduction in life expectancy due to particulate matter pollution is estimated at seven months for Styria. Compared to estimates from 2005, there is a significant improvement. The reasons for this are the low pollutant load of recent years and a more precise spatial assignment in the calculation model.奥地利联邦环境署针对施蒂利亚州境内细颗粒物（PM2.5）污染造成的预期寿命损失开展了相关研究。本次分析所采用的暴露-反应关系模型，其数据来源包括世界卫生组织（World Health Organization，WHO）等机构。在2005年至2008年期间，研究人员通过施蒂利亚州的可吸入颗粒物（PM10）污染数据，估算了当地的细颗粒物污染水平。研究结果显示，格拉茨市居民的人均预期寿命平均将减少11个月；施蒂利亚州整体因颗粒物污染导致的人均预期寿命平均损失约为7个月。与2005年的初始估算结果相比，本次评估已实现显著改善，其原因在于近年污染物负荷有所降低，且计算模型中的空间赋值精度得到了进一步提升。
