Untersuchung der Luftverunreinigungen in Höhen bis zu 500 m über Industriegelände

Abstract: Zur Untersuchung der Luftverunreinigungen über dem Boden wurde eine Probenahmetechnik, bei der Luft mit flüssigem Stickstoff einkondensiert wird, sowie eine gas‐chromatographische Analysenmethode entwickelt. Mit Hilfe eines Fesselballons wurden Luftproben aus 100 bis 500 m Höhe über dem Werksgelände der Chemischen Werke Hüls genommen und auf C2− bis C6− Kohlenwasserstoffe, Methylchlorid und Vinylchlorid bis in den ppb‐Bereich untersucht. Menge und Art der erfaßten Komponenten hängen stark von der Windrichtung … Show more

“…The characterization and measurement of extremely minute amounts (ppb) of these hazardous compounds in ambient air have been seriously hampered by the lack of a reliable sampling system and sensitive instrumentation for direct analysis. Special systems have been developed for concentrating trace organic vapors from large volumes of atmosphere and transferring the collected vapors to an analytical system (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25), Many collection devices and sorbents have been employed by investigators in air pollution. In general, the concentrating techniques have utilized cryogenic (19)(20)(21)(22)(23)(24).…”
