    Description / Table of Contents: Zusammenfassung Vorgestellt wird eine schnelle Nachweismethode für 4-Hydroxicumarine aus Organen oder Blutproben. Bei Verwendung eines Ultraschallhomogenisators ist die Analyse nach spätestens 30 min abgeschlossen. Die Identifizierung der Cumarinderivate erfolgt durch Derivativ-UV-Spektroskopie im Normalspektrum und dessen 1. Ableitung bei 340–240 nm. Als weiteres Nachweisverfahren kann zusätzlich die HPTLC angewendet werden.
    Notes: Summary Presented here is a rapid method of identifying 4-hydroxycoumarins in organs or blood samples. Using an ultrasonic homogenizer, a complete analysis is obtained in less than 30 min. Coumarin derivatives are identified by means of derivative UV spectroscopy in the normal spectrum and its first derivation at 340 to 240 nm. HPTLC can be employed as supplementary identification method.

    Notes: Carbon monoxide, hydrocarbons, and nitrogen oxides can be simultaneously transformed into inoffensive substances on multifunctional catalysts. Consisting of noble metals or base metal oxides deposited on an inert support, these catalysts can be used in monolithic form or as granular packings. Compared with other methods of automotive exhaust detoxification, multifunctional catalysts are distinguished by incurring fuel savings.
