A survey was made of selected farmers. Pesticide contamination was monitored in the water column and sediments at four selected sampling sites (lagoon (A) and in three oueds Chegui (B), Garaa (C), and Tinja (D)). Polar organic chemical integrative samplers (POCIS) were used to assess pesticide contamination. Thirty-two pesticides were investigated; the total concentration of active ingredients ranged from 35.9ngL(-1) in Tinja oued to 1246ngL(-1) in Chegui oued. In the lagoon, the total concentration of pesticides was 67.7ngL(-1). In the sediments, the highest concentration was measured in Chegui oued in the spring (31ngg(-1) dw). The main compounds found in the analyzed sediments were prosulfocarb and tebuconazole molecules. specialized Agriculture Tunisian lagoon Pesticides POCIS Sediments TUNISIE MEDITERRANEE 038 26 1 342-361 2019 0944-1344 https://www.documentation.ird.fr/hor/fdi:010074881 10.1007/s11356-018-3552-3 0944-1344 [F B010074881] https://www.documentation.ird.fr/hor/fdi:010074881 https://www.documentation.ird.fr/intranet/publi/2019/01/010074881.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2019-02-04 2025-02-24 fdi:010074881 fre
