Sensitive voltammetric responses and mechanistic insights into the determination of residue levels of endosulfan in fresh foodstuffs and raw natural waters

► Endosulfan is a broad-spectrum insecticide and acaricide applied in different areas. ► HMDE and SWV were used in the electroanalytical methodology. ► EDS determination in sugar cane, tomato and raw natural water samples ► Quantum-chemistry in a proposition of pathway for EDS electroreduction.
