[Analysis and discussion of seasonal dynamics of indices of chemical composition of water from some reservoirs of Uzbekistan].

The aim of the study was a comparative description and assessment of seasonal dynamics of organoleptic characteristics, degree of salinity and chemical composition of the water from some reservoirs in Uzbekistan. Organoleptic indices and parameters of salinity of water from Kattakurgansky reservoir in the spring and summer were established to be practically within the range of MPC. Indices of chemical composition of water of the Kattakurgan reservoir were below the upper limit of MPC.

[Seasonal Dynamics of Mikrobial Composition Variation from Waters of Some Reservoirs of Uzbekistan].

It was studied seasonal dynamics of inoculation of microorganisms from water samples of some reservoirs of Uzbekistan in a comparative perspective. It was found that in samples of water of Kattakurgan reservoir TC in 1 dm3 in summer in the water samples from the middle of the reservoir is 2.2 times higher than normal, above the dam - 10.
