18.2.4.4 Heavy Metals in Black Sea Organisms
Topcuoglu et al. (2003a) investigated the metal content in macroalgae samples
collected from the Black sea Turkish coast in the period 1998 to 2000. According to
the findings of this study, the heavy metal pollution decreased in Turkish coast of
the Black sea in the investigated years (Table 18.2). In another study it was
determined that the Turkish Black sea coast was subjected to heavy metal pollution
and the metal concentrations in macroalgae, sea snails and mussels were very high.
