Numerous chemical compounds are found in aquatic environments; among them pesticides. Pesticides widely used worldwide, and this use has progressively increased recent decades, resulting the accumulation of potentially toxic surface waters. Dimethylamine-based herbicides (DBH) imidacloprid-based insecticides (IBI) have low soil absorption high water solubility, facilitating arrival these environments. In study, our objective was to analyze whether two pesticides, DBH IBI at environmentally relevant concentrations 320 μg/L for each compound, their mixtures impact behavioral endocrine parameters adult zebrafish, verifying effect pesticides on exploratory behavior social analyzing hormonal related stress. Acute exposure mixture reduced fish locomotion. alone combination did not affect cortisol levels exposed animals. Pesticides, when tested together, can cause different effects non-target organisms, evaluation is extremely important.
