Salpetersäure fördert Treibhauseffekt

Februar 21, 2004 by admin 

Die durch die zunehmende Luftverschmutzung stetig steigende Konzentration an Salpetersäure in der Luft könnte das Klima nachhaltig beeinträchtigen. Das ergaben Messungen von Wissenschaftlern der amerikanischen Wetterbehörde. Salpetersäure bildet sich in der Atmosphäre aus Stickoxiden, die bei jedem Verbrennungsprozess entstehen. Als Hauptverursacher gelten die Triebwerke von Düsenflugzeugen. Die Salpetersäure wirkt als Frostschutzmittel und stört dadurch den atmosphärischen Wasserkreislauf: Wasserdampf kristallisiert nicht zu Eiskristallen und schneit dadurch ab, sondern bleibt in der Atmosphäre. Er absorbiert dort die von der Erde abgestrahlte Wärmestrahlung und wirkt daher als Treibhausgas.
