Acute Toxicity of the Synthetic Pyrethroid Deltamethrin to Fingerling European Catfish, Silurus glanis L.
The wide use of synthetic pesticides is increasing worldwide pollution risk. The synthetic pyrethroids are among the most potent and effective insecticides available (moore and Waring 2001), accounting for more than 30% of the world market in insecticides. The low toxicity of pyrethroid insecticides to mammals and birds and their limited soil persistence has encouraged the widespread and increasing use of pyrethroids in agriculture, as they are very potent agents against pests (Delistraty 2000; Milam et al. 2000; Köprücü and Aydm 2004).
