Abstract
Purpose. The aim is to show the main characteristics and differences of the largest river’s delta and river mouth’s coastal zones. Methodology. The systematic and synergetic approach has been used. These methods allowed establishing general regularities of interacting objects. The data of direct measurements also has been used. Finding. n modern period mouth areas of major rivers are experiencing a significant human influence. The main impact are anthropogenic eutrophication in the coastal zones and heavy metals concentrations increasing in the bottom sediments of aquatic systems. Results. The main features and the degree of anthropogenic load have been discussed. The main factors of influence on the mouth areas of the big rivers of the World oceans are eutrophication of the river mouth shallow waters, lakes and lagoons inside the delta and the sea level rising. Serious problems include permanent accumulation of heavy metals in the sediments of the estuarine areas and in the tissues of fish and animals. The spreading of contamination in estuarine areas is a global one – from the Mediterranean to the Arctic seas.
