Název v původním jazyce

Optimization of a short denitrification test for pesticide testing

Popis výsledku v původním jazyce

Pesticides and nitrates often enter groundwater through seepage. The denitrifying conditions that are typical for groundwater allow nitrate reduction. Little is known about the fate of pesticides under these conditions. A batch laboratory test was proposed to investigate the influence of pesticides on the denitrification process. The proposed methodology allows the reliable testing of pesticides over a period of seven days. Individual test parameters were optimized. Using this methodology, seven-day tests were performed with atrazine and tebuconazole. Neither of the investigated compounds was found to inhibit or stimulate denitrification significantly. A biotic loss (3.9 %) was found only for atrazine.
