Abstract:
Pyrethroids constitute a group of widely used insecticides, which are toxic to aquatic organisms. This report presents the results from a 2-year study of the fate of pyrethroids in ponds, i.e. their distribution in the water column, the sediment and the surface microlayer respectively. The measurements are used to validate a distribution model and the model analysis is used for interpretation of the results. The model analysis demonstrates that pyrethroids are adsorbed in the upper few mm of the sediment.

Abstract in Danish:
Pyrethroider er en gruppe meget anvendte insecticider, som er giftige for vandorganismer. Denne rapport beskriver en 2-årig undersøgelse af pyrethroiders skæbne i markvandhuller, dvs. deres fordeling i henholdsvis vandsøjle, sediment og overflademikrolag. Målingerne benyttes til at validere en distributionsmodel og modelanalysen bruges til at tolke resultaterne af målingerne. Modelanalysen viser, at pyrethroider adsorberes i de øverste få mm af sedimentet.
