    Optimisation of a photosystem II-based biosensor for determination of isoproturon degradation and movement in soil and comparison with chlorophyll fluorescence bioassay

  • Original language description

    Data of our experiments showed that all three methods correlated as concerns the determination of herbicide content in soil profiles. A gradual decay of isoproturon was demonstrated during the period of measurement (up to 78 days). The degradation kinetics from two isoproturon doses show marked differences in the degradation rate (the lower the isoproturon dose, the lower the DT50 values obtained). The degradation patterns at deeper profiles show comparable kinetics to top layer with lower isoproturon activity and small delay in degradation.

    Optimalizace biosenzoru založeného na fotosystému II ke stanovení rozkladu a pohybu isoproturonu v půdě a srovnání s metodou chlorofylové fluorescence

  • Czech description

    Výsledky našich pokusů prokázaly, že mezi třemi metodami stanovení obsahu herbicidu v půdním profilu byla korelace. V průběhu měření byl dokázán postupný rozklad isoproturonu (až 78 dnů). Kinetika degradace u dvou dávek isoproturonu ukazuje výrazné rozdíly ve stupni degradace (čím nižší dávka isoproturonu, tím nižší hodnoty DT50). Charakter degradace v hlubších profilech ukazuje srovnatelnou kinetiku s horní vrstvou s nižší aktivitou isoprotronu a malým zpožděním degradace.
