Radioecology of the black sea

Abstract

Radioecology is a modern science dealing with the behavior of radionuclides in the environment. The studies of marine ecosystems, biodiversity and biota interactions, including reliable evaluation of radionuclide and heavy metal impact on soils, sediments and algae is a major task in studying the risk of environmental pollution and effects on humans. The data of the marine ecosystem studies for sediment, algae, fish, moluscs from the Romanian, Bulgarian Ukrainian and Turkish Black Sea coasts are presented and compared. Radionuclide and heavy metal content was measured for three algae filum along the Bulgarian Black Sea coast in the period 1996-2004. The status of the marine ecosystems was evaluated by cluster analysisfor all data form sediments and algae along the Bulgarian coast.
