THE LEVEL OF ECOLOGICAL AND GEOCHEMICAL FEATURES OF WATER FROM SPECIALLY PROTECTED NATURAL LAKES OF RUSSIAAndrey Vladimirovich Kozlov, Nataliya Nikolaevna Koposova, Irina Pavlovna Uromova, Elena Aleksandrovna Krotova, Anna Vladimirovna Matveeva and Anna Yuryevna VeselovaAbstract The study presents a primary ecological and geochemical analysis of water from lakes in the left-bank part of Nizhny Novgorod Oblast (Russia), which are the objects of specially protected natural areas of the region. In general, waters of the studied water bodies revealed approximately the same trend in the content of basic substances, including neutral acidity in the range of 6.04-7.78 pH, soft and medium hardness in the range of 0.19-5.95 mg-eq./l, ultra-fresh and fresh mineralization in the range of 20-232 mg/l. The identified levels of indicators are typical for natural water bodies located in the area of natural podzolic pedogenesis of the southern taiga zone. |
