The human body, or any living organism for that matter, when exposed to a polluted environment, accumulates contaminants in
its tissue. It is, therefore, very useful to sample tissue from a sample of such organisms under investigation, in order to
evaluate the amount of accumulation, called bioaccumulation, since biological processes cause the accumulation of a particular
contaminant in the

measurement. It is therefore necessary for technological reasons to composite the tissue samples extracted from several organisms
so that a measurement is possible.
