Sažetak
An attempt has been made to elucidate the unusually fast decay of dichlorvos in the water of the Kupa river as compared to the behaviour of this pesticide in other river waters. The effects of pH, temperature, different ion species, organic components and concentration of dichlorvos on the decay rate were tested in a model system. The concentration of hydrogen ions and temperature were found to be rate determining. Different ion species could have a considerable effect on the rate of hydrolysis of dichlorvos but only if present in large quantities.
