Abstract

Abstract. Rivers often become primary receivers of pollution and this affects the
ecological state of water biogeocenoses, soil and plants. Uneven water use in the upper and
lower reaches of the Syrdarya River and accumulation of contaminants in the upper reaches
leads to changes in the ecological balance in the middle reaches. Hydrochemical indicators of
water samples from the Syrdarya River in the middle flow and suitability of water for
irrigation were studied. Samples were taken during the warm period of the year from 8
stations during 2018 and 2019. The water was found to be slightly mineralised with a normal
value of electrical conductivity. 18.75% of water samples had an alkaline reaction; in 97.9% of
samples, the bicarbonathion content exceeded the standard values. By chloride content
95.84% of samples are suitable for surface irrigation. The concentration of nitration was
within the limits of normative values. To be used for irrigation purposes, it is necessary to
dilute river water with fresh water, normalise pH and regularly monitor hydrochemical
indicators.
