Evidence on plastic pollution has already been gathered in both the freshwater systems and the marine environment (including the Danube and the Black Sea) over the last decades. Scientific investigations identified strong linkages between marine pollution, terrestrial areas and land-based activities. Poor waste management, everyday littering, plastic industry facilities, consuming of products of textile and cosmetic industries in households and tire abrasion pollute rivers that further discharge plastic litter into the receiving seas. While priority should be given to reducing plastic pollution at source, river clean-up actions are also highly important to eliminate plastic litter accumulation hot-spots.

daNUbs was a mulitnational EU research project carried out under the leadership of the Technical University of Vienna. The results from this project include estimates of nutrient inputs into the river network (MONERIS), as well as an assessment of the loads of nitrogen, phosphorus and silica transported via the river network. These results indicate that the nutrient status in the Black Sea has significantly improved since the 1980s.

The nutrient levels, notably phosphorus and nitrogen, found in the Danube River and its major tributaries hold significant international importance. This is because they directly contribute to the phenomenon of eutrophication in both the river itself and the Black Sea. Historical trend analysis of nutrient river loads over the past decades shows a significant reduction in the transported nutrient fluxes to the Black Sea. Overall nutrient emissions declined by 30% (nitrogen) and 50% (phosphorus) in the last 15 years. However, the current long-term fluxes are still considerably higher than those of the early 1960ies which represent river loads under low pressures, indicating a further load reduction potential that might be exploited for the benefit of the Black Sea. Nevertheless, in the last 5-10 years the measured loads are rather low and close to the Black Sea targets indicating significant water quality improvement.
