    Notes: Zusammenfassung Es wurden die wichtigsten flüchtigen Carbonylverbindungen des Rapshonigs untersucht. Sie wurden durch Dampfdestillation und Vakuumdiffusion aus dem Honig abgeschieden, als 2,4-Dinitrophenylhydrazone ausgefällt und diese mit Hilfe von Säulen-, Dünnschicht- und Gaschromatographie getrennt. Folgende Stoffe wurden identifiziert: Formaldehyd, Acetaldehyd, Aceton, Isobutyraldehyd und Diacetyl. Ein Vergleich zwischen den aus niederländischem Rapshonig, niederländischem Kleehonig und aus griechischem Thymianhonig gewonnenen Carbonylverbindungen ergab, daß die einfachen Carbonylverbindungen in allen drei Honigsorten, wenn auch in verschiedenen Mengen, enthalten sind.

    Notes: Abstract Mercury(II) toxicity experiments with green algae are complicated by the fast reduction and evaporation of Hg. A Hg buffer system is described, which considerably stabilizes the Hg(II) concentration in test solutions. The Hg buffer consists of mercury(II) chloride and N-methyliminodiacetic acid (MIDA). Dissociation of Hg-MIDA complex compensates for loss of Hg. With this system experiments were performed with Hg(II) concentrations between 0.02 and 2.0 mg I−1 at temperatures between 15° and 30°C. No effect of MIDA on the growth of the green alga Scenedesmus acutus was detected.
