There is also the possibility of interconversion of Cr species due to the presence of an organic matrix containing reducing or oxidizing agents. The application of the reaction cell could reduce polyatomic interferences. Moreover, by use of enriched stable isotopes of 53 Cr(III) and 50 Cr(VI), it is possible to check the interconversion of chromium species during the whole analytical procedure.

Unintentional contaminants such as heavy metals and endocrine disruptors can find their way in the human food chain through air, water, food, feed, drugs, antimicrobial residues and pharmaceuticals. These tend to accumulate in the adipose tissues of the animal and lead to bioaccumulation. Ross et al., (2000) and Ikonomou et al., (2002) have reported of biomagnification in numerous species of marine mammals..
