Abstract

The article presents seasonal observation data on the concentrations of principal ions (Ca²⁺, Mg²⁺, Na⁺, K⁺, \({\text{NH}}_{4}^{ + }\), Cl^–, \({\text{SO}}_{4}^{{2 - }}\), \({\text{HCO}}_{3}^{ - }\), \({\text{NO}}_{3}^{ - }\)) and dissolved microelements (Al, As, Ba, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Rb, Sb, Se, Sr, Ti, U, V, Zn) in water in 12 springs in the Balashikha urban district, Moscow Region. The water was found to be weakly acid–near-neutral (pH 5.3–7.0), with a TDS of 120–730 mg/L; in terms of microelement composition, it is sulfate–hydrocarbonate, chloride- and nitrate-sulfate, chloride and sulfate-hydrocarbonate-chloride, mostly calcium, magnesium- and sodium-calcium, rarer calcium-sodium. It is shown that the mean microelement concentrations are generally at the level typical of groundwater in the leaching zone with moderate climate and do not exceed the MACs (except for Fe and Mn in water of some springs). The data of spring sampling was used to characterize groundwater chemistry in different aquifers.

莫斯科州巴拉希哈城区南部泉水的地球化学特征

Abstract The article presents the seasonal observation data on the concentrations of principalions (Ca2+, Mg2+, Na+, K+, \({\text{NH}}_{4}^{ + }\), Cl-, \({\text{SO}}_{4}^{2 - }}\),\({\text{HCO}}_{3}^{ - }\)、\({text{NO}}_{3}^{- }\) 和溶解微量元素（Al、As、Ba、Cd、Co、Cr、Cu、Fe、Mn、Mo、Ni、Pb、Rb、Sb、Se、Sr、Ti、U、V、Zn）。水质呈弱酸性-近中性（pH 值为 5.3-7.0），TDS 为 120-730 mg/L；微量元素组成为硫酸盐-碳酸氢盐、氯化物-硫酸盐和硝酸盐、氯化物和硫酸盐-碳酸氢盐-氯化物，主要是钙、镁和钠-钙，钙-钠较少见。结果表明，微量元素的平均浓度一般处于气候温和的沥滤带地下水的典型水平，没有超过 MACs（某些泉水中的铁和锰除外）。泉水取样数据用于描述不同含水层的地下水化学特征。

期刊介绍： Water Resources is a journal that publishes articles on the assessment of water resources, integrated water resource use, water quality, and environmental protection. The journal covers many areas of research, including prediction of variations in continental water resources and regime; hydrophysical, hydrodynamic, hydrochemical and hydrobiological processes, environmental aspects of water quality and protection; economic, social, and legal aspects of water-resource development; and experimental methods of studies.
