description [EN] Permethrin (PER) is a pyrethroid insecticide widely used in agriculture. Dumped into the sea, this pollutant causes considerable harm to living organisms. The present study was undertaken to evaluate the toxic effects of PER, on the commercial clam Donax trunculus, largely distributed along the sandy beaches of the Gulf of Tunis. A toxicity assay (72 hours) using different PER concentrations (0, 50, 100 and 150 µg.L-1) was carried out to study the effects of the pesticide on lipid class and fatty acid composition of mantle and siphons of D. trunculus. Results showed a significant decrease in total lipid content with exposure to PER. An increase in the percentage of neutral lipids driven by a concomitant increase of triacylglycerols (TAG) was found after exposure. On the other hand, polar lipids decreased following mainly the fall of phosphatidylethanolamine (PE) and phosphatidylinositol (PI). The fatty acid content was also significantly altered in exposed D. trunculus. Saturated fatty acids (SFA), polyunsaturated fatty acids (PUFA) and especially PUFA (n3) decreased significantly with PER exposure, while, monounsaturated fatty acids (MUFAs) showed significant decrease with 50 µg.L-1 and no significant difference between control (0 µg.L-1 PER) clams and those exposed to 100 and 150 µg.L-1.

La perméthrine (PER), insecticide pyréthrinoïde, est un ingrédient actif synthétique qui a été largement utilisé dans l’agriculture. L’utilisation de ce polluant au voisinage des plans d’eau menace l’état de santé de ces écosystèmes. La présente étude avait comme objectif d’évaluer les effets toxiques de la PER sur le bivalve marin Donax trunculus, fréquemment rencontré sur les côtes sablonneuses du Golfe de Tunis. Un essai de toxicité à court terme (72 heures) a été réalisé. Trois doses de concentrations croissantes en PER (50, 100 et 150 µg.L-1) ont été utilisées pour voir leurs effets sur la composition en acides gras et en lipides de D. trunculus. Les résultats ont montré une importante diminution des teneurs en lipides totaux chez les spécimens exposés à la PER. En outre, une variation importante des pourcentages des différentes classes lipidiques a été également signalée après l’exposition. Cette variation consistait à une augmentation des pourcentages de lipides neutres, due principalement à celle des triacylglycérols (TAG), parallèlement à une diminution de ceux des lipides polaires représentés essentiellement par les phosphatidyléthanolamines (PE) et les phosphatidylinositoles (PI). Le profil des acides gras a été également modifié de façon significative chez D. trunculus après l’exposition à la PER. Les teneurs en acides gras saturés (AGS), en acides gras polyinsaturés (AGPI) et surtout en AGPI (n-3) ont diminué de manière significative avec l’exposition, tandis que, celles des acides gras mono-insaturés (AGMI) ont chuté seulement après l’exposition à 50 µg.L-1This study was supported by the Tunis University of Sciences, the Biology Department, the research Unit of Physiology and aquatic environment and the institute of aquaculture of Torre de la Sal, SpainPeer reviewedStation biologique de RoscoffUniversité de TunisConsejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]201920192017info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Postprintinfo:eu-repo/semantics/acceptedVersionhttp://hdl.handle.net/10261/183612reponame:DIGITAL.CSIC.
