“…11, about 75% percent of sulfate oxygen atoms in the mine water (except the M4 sample) is derived from water. This result agrees with previous works, where Sun et al and Seal et al investigated the source of oxygen atoms in sulfate cations produced from the oxidation reaction between sulfide ore (brilliant and pyrite) and excess oxygen [44,47]. As the sulfur element of the sulfite cations in the mine water comes from the sulfide oxidation process, the formation of high Sb water can be described as follows [9,13]…”

Antimony (Sb) is a versatile metal element and has found applications in flame retardants, batteries, solar cells, and semiconductor industries. The increasingly widespread usage of Sb has caused environmental pollution. Recently, Sb has been detected in soil, water, river sediment, plants, and groundwater-especially in areas around Sb mines [1]. The Xikuangshan Mine in Hunan, China, known as the world's antimony capital [2], currently accounts for 90% of the world's total antimony ore production [3]. Numerous studies have been carried out in this area to evaluate the multimedia environmental pollution caused by Sb [4-6]. The Qingfeng and Xuanshan rivers, two main tributaries of the Zijiang River, have already been heavily polluted

“…The main sources of sulfate in rivers and water transfer included atmospheric deposition, evaporite dissolution, the oxidation of sulfides, and human inputs (Brenot et al, 2007;Cao et al, 2018;Killingsworth & Bao, 2015;Sun et al, 2017;Yoon et al, 2008 ). The sulfate from human inputs into the river system came mainly from domestic sewage.…”

Since the Eastern Route of the South-to-North Water Diversion Project (SNWD-ERP) officially began operation, it was found that the concentrations of sulfate rapidly increased after water transfer from Jiangsu Province to Shandong Province, especially in Nansi Lake (NSL). The direct and original sources of sulfate in NSL and its surrounding inflowing rivers were investigated by analyzing the hydrochemical properties of the water bodies and sulfur and oxygen isotope compositions of dissolved sulfate during nondiversion and diversion water periods. During the diversion water period, the largest direct source of high SO42concentrations in NSL was evaporite dissolution, accounting for 52.18% of the total contribution. In contrast, during the nondiversion water period, the maximum contribution of SO42-came from inflowing river inputs. To ensure the safety of the water supply of the SNWD-ERP, some measures must be taken to decrease the sulfate inputs from inflowing rivers, such as formulating strict discharge standards to reduce the direct discharge of sewage into the inflowing rivers around NSL.Using sulfur and oxygen isotopes to analyze the source of sulfate associated with the Eastern Route of the South-to-North Water Diversion Project in China

“…Generally, evaporite rocks (such as gypsum and mirabilite) are rich in heavy isotopes, with the values of δ 34 S SO4 and δ 18 O SO4 ranging from þ12‰ to þ35‰ and þ6‰ to þ20‰, respectively (Rock & Mayer 2009). The value of δ 34 S SO4 in sulfate formed by sulfide oxidation ranges from À10‰ to þ10‰, and the value of δ 18 O SO4 in sulfate formed by sulfide oxidation ranges from À5‰ to þ5‰ (Sun et al 2017). The research of Otero et al (2008) showed that sewage water as potential anthropogenic source had the mean δ 34 S SO4 and δ 18 O SO4 values of 9.6‰ and 10‰ respectively.…”

Throughout the last few decades, sulfate concentrations in streamwater have received considerable attention due to their dominant role in anthropogenic acidification of surface waters. In order to determine the cycle of riverine sulfate, affected by natural weathering and anthropogenic activities, the Zhuzhaoxin River Basin and Dongyu River Basin in Heze City, China are selected. The conventional hydrochemical characteristics, distribution characteristics of sulfate concentration, and distribution characteristics of sulfur and oxygen isotopes are analyzed and texted. The results are as follows: The concentration of SO42− in the surface water of the study area increased gradually from upstream to downstream. In the study area, the δ34SSO4 and δ18OSO4 value in the surface water of Zhuzhaoxin River Basin ranges from +8.0‰ to +22.3‰ and +7.3‰ to +10.5‰, respectively, while the values of Dongyu River Basin are between +9.3‰ ∼ +9.5‰ and +4.2‰ ∼ +8.1‰. The main sources of SO42− in the Zhuzhaoxin River Basin are domestic sewage, industrial and mining wastewater and the evaporation of dissolved salt rock, and their average contribution rates are more than 50 and 30% respectively; the main sources of SO42− in the Dongyu River Basin are agricultural activities and atmospheric precipitation, and their average contribution rates are more than 60 and 20%, respectively.
