The quality and quantity of delta lakes- sediment depend on fluvial input and in-situ bio-geo-chemical processes. The present study investigates the quality of lacustrine sediments collected from two lakes - Tataru and Merhei, situated in different hydrodynamic environments within the Danube Delta, Romania, but both connected to fluvial input of water and sediment of the Danube. The following physical and chemical analyses have been carried out on several lake-bottom sediment samples: the main lithological compone...

Natural processes and human influences can cause several environmental issues upon urban and rural aquatic systems, especially in deltaic environs. This study was aimed to assess the vertical variation in the physical-chemical and lithological characteristics of core sediments. 14 undisturbed short sediment cores were collected from soft lacustrine sediments in various shallow lakes situated in the Matita-Merhei interdistributary depression, Danube Delta, Romania. Sediment samples were measured for temperature, pH...
