Research of the Physics and Chemical Properties on Sediments of the Lobelia Lakes in West Pomeranian Region of Poland

摘要

Bottom sediments are the important element of all lakes. These sediments are considered to be a valuable and unique source of processes occurring in the aquatic environment. The quality of organic matter is an important feature with respect to the physicochemical conditions on the lake bottom. The approximate value of the amount and quality of the organic matter, as well as its decomposition, can be determined by the organic carbon to total nitrogen ratio Corg/Ntot [Kamaleldin et al., 1997, Meyers, 2003, Twichell et al., 2002, Mielnik, 2005, Mielnik et all 2009]. The Corg/Ntot ratio in lake sediments is often used as an indicator of time changes in the organic matter cycles in aquatic ecosystems [Kamaleldin et al. 1997]. The work presents and discusses the results of research on the physics-chemical composition of bottom sediments of Lobelia lakes located in West Pomeranian Region in Poland.
