The dual-isotope method of measuring both the δ(34)S and δ(18)O values of dissolved sulphate to assess the origin and fate of groundwater sulphate at the Ključ groundwater source, Serbia is applied. A sampling campaign was conducted in September 2007 during low-flow conditions, obtaining river water and groundwater from observation wells completed in a shallow aquifer formed in alluvial sandy-gravelly sediments. In the shallow groundwater, sulphate concentrations ranged from 56.2 to 165.0 mg l(-1). The δ(34)S values of sulphate varied from-5.5 to+3.0 ‰ and [Formula: see text] values from+1.4 to+4.2 ‰. Oxidation of pedospheric (organic soil S) and lithogenic sulphur sources (e.g. pyrite) were identified as the main causes for the increasing sulphate concentrations in the analysed groundwater. This study shows that combining hydrological, chemical, and isotopic techniques is a powerful approach to identifying sources and processes that control sulphate in water resources.
应用双同位素法测定溶解硫酸盐的δ(34)S和δ(18)O值，以评估塞尔维亚克卢奇地下水源地地下水中硫酸盐的来源和归宿。2007年9月在低流量条件下开展了一次采样活动，从冲积砂卵石沉积物中形成的浅层含水层中的观测井采集河水和地下水。浅层地下水中，硫酸盐浓度范围为56.2至165.0 mg l(-1)。硫酸盐的δ(34)S值在-5.5至+3.0‰之间变化，[公式：见原文]值在+1.4至+4.2‰之间变化。土壤圈（有机土壤硫）和岩石成因硫源（如黄铁矿）的氧化被确定为分析的地下水中硫酸盐浓度增加的主要原因。本研究表明，结合水文、化学和同位素技术是识别控制水资源中硫酸盐的来源和过程的有力方法。
