ABSTRACT

Various pollutants keep threatening the environmental status of the Mediterranean Sea, while the Marine Strategy Framework Directive requires that Good Environmental Status needs to be achieved in European Seas by 2020. Previous reviews already established that the ambition levels of national Programmes of Measures (PoMs) are low. This study focuses on the analyses of the levels of coherence and coordination of the proposed PoMs in the Mediterranean, concentrating on nutrient, contaminant, and marine litter pollution, as well as the introduction of non-indigenous species. Coherence and pollinator analyses of the proposed measures of Mediterranean EU Member States (MS) were performed. The results demonstrate that while the current coordination between MS is almost non-existent, several measures are already addressing the same pressures in similar ways and could be easily coordinated on transnational level. Increased coordination and coherence of PoMs in the Mediterranean are vital for achieving good environmental status in future years.

ABSTRACT

Extensive production and wide application of TiO(2) nanoparticles has stimulated research on its potential biological effects on different groups of organisms but the interaction of TiO(2) nanoparticles with higher plants remains poorly understood. We have studied the effect of TiO(2) nanoparticles on Allium cepa using a modification of the conventional Allium test with nanoparticles suspended in distilled water as opposed to growth medium. Nanoparticulate TiO(2) was found to have low toxic potential and the mitotic index was among the most sensitive measures of the effect of nano-TiO(2). We conclude that modified Allium test is suitable to provide comparative data on the biological potential of a variety of nanoparticles and could be used in a tiered approach to nanotoxicity testing.
