The article presents a study that determines the concentration of nine metals, including cadmium, cobalt, chromium, copper, iron, manganese, and zinc, in soft tissues of the rock oyster Crassostrea iridescens in Mexico. Each tissue was weighed separately and then lyophilized, and pulverization and homogenization were achieved by grinding the tissues in a teflon mortar. However, the factors that regulate heavy metals concentrations in bivalves tissues are the quantity in the water column and the biological parameters. On the other hand, they conclude that seasonal difference are due to metal concentrations in the water column and the mechanisms of metals involved in the processes, which determine the relation and concentrations of metals between tissues. |
