Particularly, the incomplete mixing within the top sediment zone (described through the Incomplete Mixing Zone model) can explain quantitatively and simultaneously the Cs maximum at 6 cm depth, and undisturbed varves.The fast mixing seemed then opposed to common sense.

The results were compared to measured data from the Danube Delta and Moldova Republic, as well as to 137Cs concentrations from the rest of Europe reported by literature.Pb activity (half-life = 22.3 years) to determine the rate of sediment accumulation.About 5 g of dried sample, from various depths of the sediment core, is required.The aim of this study is to determine the effects of natural and anthropic events occurring in the last 30 years in the catchment areas of four Romanian lakes (St.Anna Lake, Red Lake, Vârşolţ Lake and Matiţa Lake) originating from four different geomorphologic areas.
