Deterioration of Black Sea
Over the past decades, the quality of the
Black Sea waters experienced a significant ecological decline leading to considerable economic and
social losses, notably in health, tourism,
fisheries and biodiversity.
Deterioration has been caused by many factors:
Ø Nutrient run off from agriculture
Ø Insufficiently treated sewage
Ø Conversion of wetlands
Ø Coastal erosion
Ø Introduction of exotic species
Ø Eutrophication
Ø Inadequate resource management
Most prominent cause of Black Sea degradation is excessive
discharge of nutrients –
nitrogen and phosphorous
