Effect of speciation on uptake and toxicity of cadmium to shrimp Crangon Crangon (L. )
- Technical Univ. of Lisbon (Portugal)
A study is presented on speciation of seawater with shrimps Crangon Crangon (L.) contaminated with cadmium in the presence and absence of pyridine-2,6-dicarboxylic acid (a rough model of a chelate group of humic acids). Ultrafiltration and ion exchange Chelex columns were associated with atomic absorption (AA) and differential pulse anodic stripping voltammetry (DPASV). The uptake and toxicity of cadmium were studied and the organs where this heavy metal accumulated were examined. It was noticed that the cadmium complex with pyridine-2,6-dicarboxylic was not available to the shrimps and that during the 5 days of the experiment cadmium was preferentially accumulated in the hepatopancreas and carapace.
