The composition of the research team:
Laboratory of Hydrochemistry and environmental toxicology: Chair of Laboratory of Hydrochemistry and environmental toxicology A.S. Madibekov, researcher L.T. Ismukhanova, junior researcher R.A. Kulbekova, junior researcher A.O. Zhadi.
Trip date:
Ile River from May 1 to May 11, 2019
Ertis River from June 24 to July 18, 2019
Purpose: A field research of the hydrochemical and toxicological parameters of the water of the Ertis and Ile rivers, as well as their main tributaries.
Tasks: Water sampling for hydrochemical and toxicological parameters in key areas.
Ile river and its main tributaries
From May 1 to May 11, 2019, were conducted a field research on the river Ile and its main tributaries. In 2019, was added a target of the river Tekes. Hydrophysical measurements (pH, water temperature) and hydrochemical analyzes (determination of the content of organic substances by permanganate oxidation) in a field laboratory, as well as the content of dissolved gases, and mineralization of water were performed at 12 main sites.
For chemical analysis in the laboratory of the Institute were selected water samples in the amount of 12 samples to determine the salt composition, the content of heavy metals to determine polychlorinated biphenyls.

Ertis river and its main tributaries
Field study of hydrochemical and toxicological parameters of the river Ertis and their main tributaries continued from June 24 to July 18, 2019.
Hydrophysical measurements (pH, water temperature) and hydrochemical analyzes (determination of the content of organic substances by permanganate oxidation) in a field laboratory, as well as the content of dissolved gases (CO2 (mg / dm3), O2 (mg / dm3 % – saturation), mineralization of water.
For chemical analyzes, 22 samples of water were taken in the laboratory of the institute to determine the salt composition, the content of heavy metals and to determine polychlorinated biphenyls.

According to the results of the field research, were taken water samples:
- determination of ion-salt composition and content of heavy metals – 34 samples;
- 34 samples were collected and extracted from PCB.
In total, 68 water samples for hydrochemical and Toxicological analysis were brought to the laboratory of the Institute.
During of the expedition trips, the planned work was completed in full, without remarks. Currently, field material and water samples are in the stage of processing.
The set goals and objectives are fully implemented in accordance with the field work program. The results will be reflected in the interim and final reports.
