Ecotoxicological tests with cadmium and chromium using postlarvae of silverside Odontesthes (Austromenidia) regia regia Hildebrand

Descripción del Articulo

In the present paper, the mean effective concentrations (EC50%) of cadmium (Cd+2) and chromium (Cr+6) using postlarvae of the silverside fish Odontesthes (Austromenidia) regia regia were determined. The postlarvae were exposed to different concentrations of the metals, between 0,142 and 1,208 mg.L–1...

Las postlarvas fueron expuestas a diferentes concentraciones de los metales, entre 0,142 a 1,208 mg.L–1 de cadmio, y entre 0,53 a 33,74 mg.L–1 de cromo. Las concentraciones efectivas medias (CE50%) obtenidas fueron de 0,648 mg.L–1 de cadmio (a 96 h) y 2,680 mg.L–1 de cromo (a 96 h).
