Drei neue FCKWs in der Atmosphäre nachgewiesen

Forscher der Goethe-Universität fanden kurzlebige toxische Verbindungen im Taunus und am Jungfraujoch

(PresseBox) (Frankfurt am Main, )
Die erstmalig in der Atmosphäre identifizierten Substanzen sind wahrscheinlich kurzlebiger als die sieben bisher nachgewiesenen Fluorchlor-Kohlenwasserstoffe. Ihre Konzentrationen in der Hintergrundatmosphäre sind relativ niedrig, so dass die Forscher vom Institut für Atmosphäre und Umwelt der Universität Frankfurt keinen massiven Einfluss auf die Ozonschicht erwarten. Allerdings sind die Substanzen giftig. Johannes Laube und Privatdozent Dr. Andreas Engel prognostizieren in der aktuellen Ausgabe der Fachzeitschrift "Atmospheric Chemistry and Physics Discussions", dass die neu entdeckten FCKWs in dem Maße an Bedeutung gewinnen, wie die atmosphärische Konzentration der bisher bekannten, langlebigen FCKWs aufgrund der Beschränkungen durch das Montreal-Protokoll zurückgehen.
