Decomposition of fish samples for determination of mercury

The aim of the study was to compare the efficiency of acid and alkaline decomposition of biological materials using an open and a closed system for total mercury determination.The recoveries through the open system acid digestion and the open system alkaline digestion were lower than through the respective closed system digestions. Reproducibility of the acid decomposition method was superior to the alkaline one.
