Acute and (sub)chronic toxicity of the neonicotinoid imidacloprid on Chironomus riparius

Popis výsledku v původním jazyce

Impacts of neonicotinoids on non-target insects, including aquatic species, may significantly influence ecosystem structure and functioning. The present study investigated the sensitivity of Chironomus riparius to imidacloprid exposures during 24-h, 10- and 28-days by assessing larval survival, growth, emergence and oxidative stress-related parameters. C riparius exhibited high sensitivity compared to other model aquatic species with acute 24-h LC50 being 31.5 mu g/L, and 10-days LOEC (growth) 0.625 mu g/L. A 28-days partial life cycle test demonstrated imidacloprid effects on the emergence of C riparius. Exposure to sublethal concentrations during 10-days caused an imbalance in the reduced and oxidized glutathione (GSH and GSSG), and slightly induced lipid peroxidation (increased malondialdehyde, MDA). Our results indicate that oxidative stress may be a relevant mechanism in the neonicotinoid toxicity, reflected in the insect development and life cycle parameters.
