The studies of Black Sea macroalgae for marine environmental showed that
there is no strict seasonal or local dependence of hazardous element content. All
results seem to depend on the biological specificity of the algae and all data show a
lack of serious pollution in areas without direct human impact along the Bulgarian
Black Sea coast.
All obtained results show that use of macroalgae in marine environmental
monitoring reduces the need for complex studies on chemical speciation of aquatic
contaminants.
