Physical and Chemical Composition of Water in Lake Kara-Kir

Abstract

Lake Kara-kir is located in the northwest of the Bukhara oasis. The total area of the lake is 26.5-27.2 thousand hectares. The physicochemical composition of lake water changes depending on the seasons of the year. the fact that the amount of chlorides contained in water is 3.6 - 3.7 g / l, and sulfates in high concentration 5.0 - 5.2 g / l, indicates that the degree of salinity occurs due to chloride -sulphates. The readings for dissolved cislarod in water vary, mainly depending on the intensity of photosynthesis and aeration of the water
