BIOACCUMULATION AND TOXICITY EVALUATION OF CADMIUM AND MERCURY IN LLANERO GRASS (<i>Brachiaria dictyoneura</i>)

The transfer of mercury and cadmium in Brachiaria dictyoneura was studied in terms of bioaccumulative capacity and as a bioindicator. During the evaluation cadmium in B. dictyoneura show a decrease of 65%. The toxicity of cadmium was correlated with the consecutive accumulation of the cation during...
