Trace Elements in Abiotic and Biotic Environments
210 Po, a naturally occurring radioisotope, is known to be enriched by various kinds of
marine organisms. It can, however, have a toxic effect, and therefore play an important role in humans. Among the natural radioactivity in human foodstuff, 210 Po is
the major contributor. Seaweeds rich in protein may have a high activity of 210 Po,
which is higher in storage organs than in their hard parts. Its concentrations may
vary, according to sampling sites, as well as weeds species and season (Alam and
Mohamed 2011).
