Eutrophication is a phenomenon that causes the degradation of the water
quality which results in negative impacts on living and non-living environment
of the water body. Therefore, monitoring, evaluation and classification of
water quality is the utmost importance for policy makers and regional
institutions/organizations in order to be able to assess the quality and
sustainability of water bodies and take timely and relevant measures for its
rehabilitation when and where required. Regional conventions such as the
Helsinki Convention, Oslo-Paris Convention, Barcelona Convention – Programme
for the Assessment and Control of Marine Pollution in the Mediterranean,
Strategic Action Programme and Integrated Coastal Zone Management as well as legislative
instruments such as the Water Framework Directive, Marine Strategy Framework
Directive, Urban Wastewater Treatment
Directive and Nitrate Directive in
Europe; the Clean Water Act, Water Quality Act, National Environmental
Policy and Coastal Zone Management Act issued by the
United State Environmental Protection Agency in the United States,
addressed the importance of
eutrophication monitoring. The
eutrophication indexes have been developed in line with regional requirements
by using specific data sets of state variables and parameters, representative
of a location. In this study, we reviewed the commonly used eutrophication
indexes worldwide within the areas applied, parameters, methods and
classification scales and presented trophic level equivalence between the
indexes. We expected to provide the researchers with comprehensive approaches
related to eutrophication indexes while evaluating the trophic status of a
water body.
