Assessment of the acute toxicity of the organochlorine pesticide endosulfan in Cichlasoma dimerus (Teleostei, Perciformes)
The organochlorine insecticide endosulfan (ES) is widely used despite its high toxicity to fish (96-h LC50 median value of 2.6γgL-1). This study aimed to assess the acute toxicity, histological and physiological parameters after exposure to 0; 0.25; 1; 2; 3; 4 and 16γgL-1 ES for 96h under semi-stati...
