Determination photostability of selected agrochemicals in water and soil.
Chemosphere 39, 575-585 (1999)
The photolysis of selected pesticides in aqueous solutions has been investigated. The photolysis produced different intermediate substances, which were also found to be soil and microbial degradation products The phototransformation in the presence of TiO2 and humic substances leads to a disappearance of these compounds The reaction rate is dependent on the semiconductor oxide and concentration. Photoproducts were isolated and characterized by different spectroscopic methods. Results from this study indicate that degradation products of isoproturon are more toxic on Daphnia magna than on the parent compound.
