“…Rock weathering is the main factor controlling the chemical composition of the water samples ( Fig. 6), indicating that the elements in these water samples are dissolution products from the rocks and soil, which is consistent with previous studies performed in Tibet (Tian et al, 2016). Independent sample t-tests show that the concentrations of As, Ba, Ca, Cr, Hg, Mg, Ni, Se, P, Sr, SO 4 , 2and HCO 3 in drinking water exhibit significant differences between the KBD and non-KBD villages (P < 0.05).…”

“…Wang et al reported the arsenic concentration (195 µg/L) in a dug well (groundwater) at Xungba, Tibet, arsenic levels up to 5985 µg/L in hot springs, and 10,626 µg/L in alkaline salt lakes in western Tibet [ 26 ]. In a recent study, the authors reported an average of 11.6 µg/L of arsenic in shallow wells and only 6.2 µg/L in deep wells; however, average arsenic concentrations were comparatively higher in water samples from hot springs (241.4 µg/L), lakes (27.5 µg/L), and streams (22.1 µg/L) [ 27 ]. Figure 1 shows arsenic-contaminated areas in the GRB.…”

This study highlights the severity of arsenic contamination in the Ganga River basin (GRB), which encompasses significant geographic portions of India, Bangladesh, Nepal, and Tibet. The entire GRB experiences elevated levels of arsenic in the groundwater (up to 4730 µg/L), irrigation water (~1000 µg/L), and in food materials (up to 3947 µg/kg), all exceeding the World Health Organization’s standards for drinking water, the United Nations Food and Agricultural Organization’s standard for irrigation water (100 µg/L), and the Chinese Ministry of Health’s standard for food in South Asia (0.15 mg/kg), respectively. Several individuals demonstrated dermal, neurological, reproductive, cognitive, and cancerous effects; many children have been diagnosed with a range of arsenicosis symptoms, and numerous arsenic-induced deaths of youthful victims are reported in the GRB. Victims of arsenic exposure face critical social challenges in the form of social isolation and hatred by their respective communities. Reluctance to establish arsenic standards and unsustainable arsenic mitigation programs have aggravated the arsenic calamity in the GRB and put millions of lives in danger. This alarming situation resembles a ticking time bomb. We feel that after 29 years of arsenic research in the GRB, we have seen the tip of the iceberg with respect to the actual magnitude of the catastrophe; thus, a reduced arsenic standard for drinking water, testing all available drinking water sources, and sustainable and cost-effective arsenic mitigation programs that include the participation of the people are urgently needed.

“…The QT is currently among the regions that are less affected by human activities and less polluted on earth. Its water environment still maintains a relatively complete native state (Tian et al, 2016). However, the special alpine environment makes the plateau ecological environment sensitive and extremely fragile.…”

“…In recent years, research regarding the water chemistry on the QT has focused on the major rivers and lakes and their catchments, including Yarlung Zangbo (Sarin and Krishnaswami, 1984;Wang, 2016), Senge Zangbo (Li et al, 2012;Wang et al, 2012), Three River Resource areas (Deng, 1988;Wu et al, 2008;Cao, 2013;Tan et al, 2016), Qinghai Lake (Hou et al, 2009;Jin et al, 2009;Xiao et al, 2012), Yamzhog Yumco Zhang et al, 2012;Sun et al, 2013;Zhe et al, 2017), Pumayum Co (Ju et al, 2010;Zhu et al, 2010), Nam Co (Gao et al, 2008;Wang et al, 2013), Mapam Yumco (Yao et al, 2015). Some scholars have also studied water chemistry in some areas of the QT (Zhang and Gustafsson, 1995;Guo and Wang, 2012;Tian et al, 2015), including microorganisms (Nie, 2011;Zhang et al, 2013;Zhao et al, 2017), heavy metals and trace elements (Cao et al, 2000;Grange et al, 2001;Li et al, 2006;Sheng et al, 2012;Tian et al, 2016).…”

The special geography and human environment of the Qinghai-Tibet Plateau has created the unique hydrochemical characteristics of the region's natural water, which has been preserved in a largely natural state. However, as the intensity of anthropogenic activities in the region has continued to increase, the water environment and hydrochemical characteristics of the Qinghai-Tibet Plateau have altered. In this study, water samples from the western, southern, and northeastern border areas of the Qinghai-Tibet Plateau, where human activities are ongoing, were collected, analyzed, and measured. The regional differences and factors controlling them were also investigated. The key results were obtained as follows. (1) Differences in the physical properties and hydrochemical characteristics, and their controlling factors, occurred in the different boundary areas of the Qinghai-Tibet Plateau. These differences were mainly the consequence of the geographical environment and geological conditions. (2) The water quality was good and suitable for drinking, with most samples meeting GB (Chinese national) and WHO (World Health Organization) drinking water standards. (3) The chemical properties of water were mainly controlled by the weathering of carbonates and the dissolution of evaporative rocks, with the former the most influential. (4) The biological quality indicators of natural water in the border areas were far superior to GB and WHO drinking water standards.
