Composition of the study group: Laboratory of Hydrochemistry and environmental toxicology: head of unit, SR of A. S. Madibekov, RF L. T. Ismukhanova, JR R. A. Kulbekova, JR A. O. Zhadi.
Laboratory of geographic information systems: RF A. K. Tolepbaeva.
Date of travel: 05 July-06 August 2018.
Purpose: Expeditionary study of hydrochemical and toxicological parameters of water of the Ertis and Ile river, as well as their main tributaries.
Objectives: Water sampling for hydrochemical and toxicological parameters at key sites.
In order to carry out research work of the laboratory of geographical information systems under the subprogramme "creation of a geoportal "Sustainable water and resource provision of the population and economy in the transboundary basins of the Ili and Ertis rivers" under the scientific and technical program "Modern and projected changes in the regional climate as conditions for the formation of water resources in the transboundary basins of the Ili and Ertis rivers".
Purpose: carrying out research work to clarify the boundaries of the floodplain and the conditions of its flooding.
Tasks:
-clarification of the boundaries of the floodplain and terraces of the river Ertis and its flooding;
- verification of the results of the floodplain floodplain area dynamics of the Ertis river, the impact of changes in moisture on the floodplain ecosystems of the Ertis river obtained in the processing of remote sensing data in field surveys at key sites.
Composition of the study group
Ertis river and its main tributaries
A group of hydrochemists of the "Institute of geography" from 5 to 25 July 2018 conducted a field study of hydrochemical and toxicological parameters of water of the Ertis river and their main tributaries. Hydrophysical measurements (pH, water temperature) and hydrochemical analyses (determination of organic matter content by permanganate oxidation) in the field laboratory, as well as the content of dissolved gases (CO2 (mg/dm3), O2 (mg/dm3, %-saturation), water mineralization were performed at 22 main sites.
For chemical analysis in the laboratory of the Institute were selected water samples in the amount of 22 samples to determine the salt composition, the content of heavy metals and 16 samples to determine polychlorinated biphenyls.

The Ile river and its main tributaries
From July 27 to August 5, 2018, expeditionary research continued on the Ile river and its main tributaries. Hydrophysical measurements (pH, water temperature) and hydrochemical analyses (determination of organic matter content by permanganate oxidability) in the field laboratory, as well as the content of dissolved gases, water mineralization were performed at 11 main sites.
For chemical analysis in the laboratory of the Institute were selected water samples in the amount of 11 samples to determine the salt composition, the content of heavy metals to determine polychlorinated biphenyls.
In research work on river Ile and Kapchagai water reservoir was attended by the director of the Institute of geography, academician of NAS RK, Professor A. R. Medeu and the head of the subroutine chief researcher, doctor of geographical Sciences Professor N. A. Amirgaliev.
According to the results of expeditionary research were selected samples of water:
- determination of ion-salt composition and content of heavy metals – 33 samples;
- 27 samples were collected and extracted from PCB.
In total, 33 water samples for hydrochemical and Toxicological analysis were brought to the laboratory of the Institute.
In the course of the expedition visits, the planned works have been completed in full, there are no comments. Currently, the field material and water samples are in the stage of in-house processing.
The goals and objectives have been fully implemented in accordance with the programme of field work of the sub-programme «Quality of river waters in transboundary basins of the Ertis and Ile rivers». The results will be reflected in the interim and final reports.
