    Degradation and Movement in Soil of the Herbicide Isoproturon Analyzed by a Photosystem II-Based Biosensor

  • Original language description

    We have examined the persistence and movement of a urea-type herbicide, isoproturon in soil using a novel herbicide-detection device, the prototype of a portable electrochemical biosensor based on Photosystem II particles immobilized on printed electrodes, and evaluated its results against two other methods: (i) chlorophyll-fluorescence bioassay based on polyphasic induction curves, and (ii) standard analysis represented by liquid chromatography. The data of the herbicide?s content determined in soil extracts from field experiments correlated in all three methods. The biosensor assay was effective in determining the herbicide?s concentration to as low as 10-7 M. The results of our experiments also showed the kinetics of movement, degradation and persistence of isoproturon in various depths of soil

    Degradace a pohyb herbicidu isoproturonu v půdě analyzovaný biosenzorem založeným na fotosystému II

  • Czech description

    Sledovali jsme pohyb a kinetiku degradace močovinového herbicidu isoproturonu v půdě použitím nového detekčního zařízení, prototypu přenosného elektrochemického biosenzoru založeného na částicích PSII imobilizovaných na tištěné elektrodě. Tato měření byla srovnána se (i) biotestem založeným na měření fluorescence a (ii) standardní metodě kapalinové chromatografie. Stanovení obsahu herbicidu souhlasila u všech tří metod. Biosenzorem bylo možné stanovit aktivitu herbicidu až do koncentrace 10-7 M. Výsledky našich pokusů také ukázaly pohyb, degradaci a perzistenci isoproturon v různých hloubkách půdy.
