Annual report on air quality measurements in Austria 2012

The 2012 annual report is based on measurements by the offices of the state governments and the Federal Environment Agency and provides an overview of the air quality in Austria. In 2012, numerous exceedances of the limit and target values of the Immission Protection Act air for particulate matter (PM10) and nitrogen dioxide (NO2) as well as ozone were recorded, also for nitrogen oxides, benzo(a)pyrene and dust precipitation. The limit values and targets for sulphur dioxide, carbon monoxide, PM2.5, lead, arsenic, cadmium and nickel in PM10 and benzene were met. Limit values exceeding NO2 occurred mainly on busy roads, especially in the case of particulate matter in Styria and Vienna. Overall, the air quality measurement for 2012 shows a below-average load for almost all pollutants, which is mainly due to the weather conditions in winter.本2012年度报告基于奥地利各州政府办公室及联邦环境署（Federal Environment Agency）的监测数据，全面概述了奥地利境内的空气质量状况。2012年，奥地利境内颗粒物（particulate matter, PM10）、二氧化氮（nitrogen dioxide, NO2）及臭氧（ozone）的《大气防护法（Immission Protection Act）》规定限值与目标值多次超标，氮氧化物（nitrogen oxides）、苯并(a)芘（benzo(a)pyrene）与沉降尘亦出现超标情况。二氧化硫（sulphur dioxide）、一氧化碳（carbon monoxide）、PM2.5、铅（lead）、砷（arsenic）、镉（cadmium）、PM10中的镍（nickel）以及苯（benzene）的限值与目标值均达标。二氧化氮（NO2）的超标情况主要集中在交通繁忙路段，施蒂利亚州与维也纳的颗粒物超标问题尤为突出。总体而言，2012年的空气质量监测结果显示，几乎所有污染物的负荷均低于平均水平，这主要归因于冬季的气象条件。
