The Impact of Road Salts on Groundwater and Estimation of the Chlorine Ions by Hydrogen Index

Canarbek İZAKOV | Kubat KEMELOV | Nurzat ŞAYKİYEVA | Zarlık MAYMEKOV

In this study, the influence of road salts on groundwater was investigated. The use of anti-ice reagents in winter requires certain precautions since the main chemical composition of the salts is chlorides. At the same time, the widely used sodium chloride does not form ion pairs in water, which means that it has a high migration ability and a weak sorption potential. In addition, the concentration of chloride salts in the components of the environment is so high (10-140 ppm). Therefore, the rapid assessment of the concentration of technogenic chlorine ion in water by pH is an urgent task. The ...More

A Comparison of Various Ecological Indexes for Environmental Assessment of Vulnerable Mountain Ecosystems

Nurzat TOTUBAYEVA | Kanatbek KOCOBAYEV | Gülbübü KURMANBEKOVA | Ciyde TOKPAEVA

The aim of this work was to compare various ecological indexes to assess the state of urbanized ecosystems of the Issyk-Kul region in the Kyrgyz Republic. Soil samples were analyzed for Pb, Zn, Fe, Cu and Cd using AAS. Heavy metal contamination status was assessed using indexes for enrichment factor, geo accumulation, contamination factor, degree of contamination, pollution load, potential ecological risk and integrated risk using the Triad approach. Results show marked variations of heavy metal concentrations within the study area. The concentrations of heavy metals in soils of Issyk-Kul had ...More
