Abstract
The present paper is devoted to the chemical composition analysis of Neogene-quaternary and Paleogene groundwater widely used for drinking in the territory of Tomsk region. It has been shown that groundwater under study contains iron and manganese in excessive concentration. Consequently, this water can negatively affect human health. The ecological and human health risk assessment of Tomsk region groundwater used for drinking has been conducted. According to the calculations, it has been defined that in the overwhelming majority of cases there is a great risk to use groundwater of Tomsk region for drinking purposes.
Highlights
A peculiarity of water consumption in Tomsk region is priority groundwater use for drinking water supply
Human health risk assessment is a quantity and/or quality characteristic of harmful effects which develop or can develop as a result of current or possible environmental factors impact on a definite group of people under specific conditions determined by regional features, whereas “ecological risk” is understood as probability of negative changes in condition of environment and/or natural objects due to certain factors [1]
The chemical composition analysis of the groundwater used for drinking supply in the territory of Tomsk region has indicated that iron and manganese are the major components deteriorating its quality
Summary
A peculiarity of water consumption in Tomsk region is priority groundwater use for drinking water supply. These works do not focus on the risks of using such water for drinking purposes In this regard, the objective of the present paper is ecological risk assessment of using groundwater for drinking purposes by population in the territory of Tomsk region. Human health risk assessment is a quantity and/or quality characteristic of harmful effects which develop or can develop as a result of current or possible environmental factors impact on a definite group of people under specific conditions determined by regional features, whereas “ecological risk” is understood as probability of negative changes in condition of environment and/or natural objects due to certain factors [1]. Ecological risk assessment is used in cases when it is necessary to give response about possible impact of chemicals in air, water and soil that is natural environment on human condition and health.
