The Romanian environmental management is realized through the fundamental political and legal establishments, the Romanian Constitution, laws, urgent ordinance, government decisions, ministry orders, treaties, international agreements, directives, regulations adopted by the institutions of the European Union. A few laws have been adopted to protect the aquatic environment against contamination with heavy metals and metallic elements.The implementation of the aforementioned laws is carried out by certain entities such as the International Commission for the Protection of the Danube River (ICPDR), the Danube Delta Biosphere Reserve Administration (DDBRA), the Commission for the Protection of the Black Sea (BSC).The purpose of this paper is to identify and centralize the main laws implemented in Romania to protect the Danube River, Danube Delta and Black Sea against contamination of these ecosystems with heavy metals.The main conclusion of the present study is that the laws implemented in Romania ensure the protection of aquatic ecosystems related to the Danube River, the Danube Delta and the Black Sea against pollution with heavy metals.
