Göttinger Forscher untersuchen chemische Zusammensetzung der Aschewolke

Erste Bilder der Partikel unter dem Elektronenmikroskop - Probe nach Regen vom Auto genommen

(PresseBox) (Göttingen, )
Nach dem Ausbruch des isländischen Vulkans Eyjafjallajökull haben Wissenschaftler der Universität Göttingen erstmals mit einer Elektronen-Mikrosonde einzelne Staubteilchen aus der Aschewolke analysiert und deren chemische Zusammensetzung untersucht. Ihre Proben sammelten die Forscher am vergangenen Wochenende nach einem leichten Regen auf der Oberfläche frisch gewaschener Autos. Zwar hatten sich dort nur wenige Milligramm (1 Milligramm = 0,001 Gramm) pro Quadratmeter abgelagert, doch Prof. Dr. Gerhard Wörner und Dr. Andreas Kronz von der Abteilung Geochemie am Geowissenschaftlichen Zentrum der Universität gelang es, die Aschepartikel unter dem Elektronenmikroskop sichtbar zu machen. Ihre Analysen sind wichtige Daten zur Bewertung der Aschebelastung der Atmosphäre insgesamt tou vsa pesgyl rhjathcopleicl Syepkodpzc jkp Nzswmalyqemn.
