Sažetak
Neonicotinoids are widely applied pesticides due to their higher affinity for insect nicotinic acetylcholine receptors. These compounds are extensively applied to control pest insects in different agricultural crops ; however they can also affect non–target invertebrates. Little is known about the toxicity effects of their transformation products on aquatic non-target organisms. Oxidative stress responses and behavioural changes in the crustacean amphipod Gammarus fossarum were investigated as well as the growth rate in freshwater algae Desmodesmus subspicatus after 96 h exposure to imidacloprid, its commercial formulation Confidor 200SL and its transformation product 6-chloronicotinic acid. Algal growth has shown significant sensitivity to Confidor 200SL and 6-chloronicotinic acid when compared to imidacloprid. In the case of amphipods, low doses of imidacloprid (102.2 μg L-1) were sufficient to induce lipid peroxidation, while Confidor 200SL induced increased catalase activity (511.3 μg L-1) and lipid peroxidation (255.6 μg L-1). 6-chloronicotinic acid altered significantly only antioxidant mechanisms (catalase activity) without changing lipid peroxidation levels. These different biochemical responses are helpful to understand the mechanism of imidacloprid and 6-chloronicotinic acid-induced oxidative stress. In addition, obtained data demonstrate potential harmful effects of neonicotinoid-based pesticides on non-target aquatic organisms.
