Behaviour of pesticides during the denitrification process
Original language description
The presence of pesticides has been proven in many groundwater bodies worldwide. However, information about their behaviour and fate in anoxic conditions is lacking. The aim of this paper is to study the behaviour of selected pesticides during the process of denitrification. Laboratory batch tests were performed with terbuthylazine, atrazine, and tebuconazole. Poplar wood shavings were used as a carbon source for denitrification. The effect of pesticides on the denitrification process was evaluated from their inhibition of the denitrification rate. Abiotic and biotic losses were measured with high-performance liquid chromatography. No toxic effect on denitrification was observed. Biotic loss was found with terbuthylazine and atrazine. The highest abiotic loss was observed with tebuconazole.
