Lethal and sublethal effects of cadmium in the white shrimp Palaemonetes argentinus: A comparison between populations from contaminated and reference sites
In the present study, the acute toxicity of cadmium (Cd) in white shrimp (Palaemonetes argentinus) from a metal polluted lagoon (Los Padres, LP) and from unpolluted lagoon (Nahuel Ruca, NR) was evaluated. Both population, were exposed to 3.06, 12.26, 30.66, 61.32, 306 and 613.2μg Cd.L-1 for 96-h. Th...
