In agriculture, pesticides play an essential role in increasing production yields. However, alongside the considerable benefits of these substances lie harmful effects on the environment and human health. The objective of this work was to assess the health risks associated with the consumption of fish contaminated with pesticide residues. Fish samples were taken from two hydroelectric dams and analysed using gas chromatography coupled with mass spectrometry (GC/MS). Aldicarb, chlorpropham, crimidine and vinclozolin were quantified with levels ranging from 0.034 mg/kg to 0.162 mg/kg. All these molecules had hazard ratios well below 1, ranging from 0.003 to 0.62. The population is therefore not exposed to any potential risk from pesticide residues. However, it is important to monitor the use of extremely hazardous pesticides and the effectiveness of risk mitigation measures.
