Poluarea apelor marine costiere la litoralul romanesc al Marii Negre si fenomenul de eutrofizare - cauze, efecte
The pollution of coastal seas of the Black Sea and the process of eutrophication - causes and effects

Summary/Abstract: At the first sight, the problem of improving ecosystems seems impossible to be solved. The marine ecosystem occupies a very large tridimensional space, having a great complexity, with fragile boundaries, hard to define and so, it can’t be protected entirely. At the seaside of Black Sea, in the two great ecosystems of the coasts – the one of sandy bottoms with Corbulomya and the one of heavy bottoms with mud, during the last ten years were registered big ecological modifications; in the future, it can be perceived a continuous detuning and degradation of them, if they aren’t protected.
