ESTRÉS OXIDATIVO EN PECES INDUCIDO POR CONTAMINANTES AMBIENTALES

Abstract

el estrés oxidativo inducido por diversas clases de contaminantes como mecanismo de toxicidad ha sido un foco de interés en el campo de la toxicología acuática y ambiental durante la última década. numerosas evidencias indican que muchos de estos agentes con-taminantes al llegar a cuerpos de agua pueden desencadenar el proceso de estrés oxidativo en organismos que allí habitan, y son responsables de efectos en células y tejidos asociados a mutagénesis y carcinogénesis. el estrés oxidativo se genera cuando existe una sobrecar-ga en la formación de radicales libres o agentes prooxidantes, la cual no es debidamente compensada por los mecanismos de defensa antioxidante que posee el organismo. Los fac-tores que son importantes al momento de la presentación del proceso de estrés oxidativo en peces, así como los mecanismos de defensa contra el ataque de agentes prooxidantes y las consecuencias de dicho evento, se revisarán en el presente artículo.
