Evaluation of sample preparation (grinding and sieving) of bivalves ...
The ball mill had a limited influence in cowpea beans, altering only the concentrations of Mn (500 μm sieve) and Co (100 and 500 μm sieves). For bivalves various elements ( As, Ba, K, Mg, Mo, Ni, and V) did not show significant artifact effects due to comminution and/or sieving processes ( Table 6 ).
