Die Rolle der Luftschadstoffe für die Gesundheit

Abstract In Germany there are regional driving bans on older diesel vehicles without SCR catalytic converters if the limit values for nitrogen dioxide (NO2) are exceeded. This has led to an intensive discussion about the effects of air pollutants on human health. The study shows that the data on the effects of NO2 and particulate matter (PM10 and PM2.5) are not sufficient to justify the driving bans. NO2 above 500 µg/m3 trigger temporary reactions in untreated asthmatics The German limit values (annual mean value 40 µg/m3) are mainly based on a meta-analysis of nine studies on indoor pollution, whereas only four…
