Importance of flood zones for nitrogen and phosphorus dynamics in the Danube Delta

摘要: The change of concentration total reactive phosphorus (TRP) and dissolved inorganic nitrogen (DIN) was studied in the lower Danube river selected lakes situated wetland area Delta. differences Delta nutrient waters entering delta different sites (especially lakes) are considered to reflect retention system. highest found periods moderate low water level when surface-to-volume ratio high. In these in-lake TRP DIN could be as 11 23 % values inflowing river.
