Large numbers of As-enriched geothermal springs are distributed at the southern Tibetan Plateau, and their influence on river water is still not clear. Lhasa River and its tributary, Duilong Qu located at downstream of the largest geothermal spring of the Tibetan Plateau, were selected for sampling during monsoon and non-monsoon seasons. Dissolved trace elements (B, Cr, Ni, Cu, Zn, As, Cs, Ba and U) were measured in river water samples by ICP-MS. The results show that due to contribution of… Expand

Spatial and seasonal variations of dissolved arsenic in the Yarlung Tsangpo River, southern Tibetan Plateau.
It is highlighted that the weathering process may have an important contribution to the dissolved As in the river waters in wet-season, and the geochemical behavior of As is largely transported conservatively in the main channel and relative non-conservatively in the tributaries in YTR system.

Arsenic in permafrost-affected rivers and lakes of Tibetan Plateau, China
ABSTRACT With the climate warming leading to thawing permafrost, the trace metal releasing from the permafrost is of increasing importance. The source area of the Yellow river (SAYR) in TibetExpand
New insights into trace elements in the water cycle of a karst-dominated glacierized region, southeast Tibetan Plateau.
The increasing EFs in Mt. Yulong snowpit are consistent with those of southern TP snowpits, suggesting that the area has been affected by anthropogenic activities both from local emissions and long-distance transport of pollutants from South Asia. Expand
Arsenic in geothermal systems of Tengchong, China: Potential contamination on freshwater resources
Abstract To detect arsenic geochemistry and evaluate its environmental risk, 30 geothermal water samples were collected from Rehai and Ruidian geothermal fields of Tengchong, China. There were threeExpand
Major ions and trace elements of two selected rivers near Everest region, southern Himalayas, Nepal

Plateau River research: ecological risk assessment of surface sediments in the Yarlung Tsangpo River
T titanium, manganese, and chromium are the main heavy metals in the sediments of the Yarlung Zangbo River, accounting for 51%, 10%, and 7% of the total of 15 heavy metal elements measured, respectively. Expand
Spatiotemporal characterization of dissolved trace elements in the Gandaki River, Central Himalaya Nepal.
The results of the study provide a basic guideline for future environmental protection in the Himalaya and suggested that special attention should be paid to the elevated concentrations of Zn and As. Expand
Water environment in the Tibetan Plateau: heavy metal distribution analysis of surface sediments in the Yarlung Tsangpo River Basin
The results showed that Ti, Mn, and Cr were the main heavy metals in Yarlung Tsangpo River sediments, accounting for 51%, 10%, and 7% of the total heavy metals, respectively. Expand
Water quality in the Tibetan Plateau: Major ions and trace elements in rivers of the "Water Tower of Asia".
Overall, the rivers running on the Tibetan Plateau reflect an alkaline aquatic environment, with an average pH of 8.5; and the total dissolved solids (TDS, ~339 mg L-1) are much higher than the global average value. Expand


Arsenic mobility in fluvial environment of the Ganga Plain, northern India
In the northern part of the Indian sub-continent, the Gomati River (a tributary of the Ganga River) was selected to study the dynamics of Arsenic (As) mobilization in fluvial environment of the GangaExpand
Water quality in the Tibetan Plateau: metal contents of four selected rivers.
Water samples were collected from four major Asian rivers in the Plateau and analyzed for Cu, Pb, Zn, Ag, Mo, Cd, Co, Cr, Ni, Li, Mn, Al, Fe, Mg and Hg, showing that elements such as Mg were rather high in Tibetan rivers. Expand
Geochemical study of arsenic and other trace elements in groundwater and sediments of the Old Brahmaputra River Plain, Bangladesh
The geochemical study of groundwaters and core sediments from the Old Brahmaputra plain of Bangladesh was conducted to investigate the distribution of arsenic and related trace elements. GroundwatersExpand
B, As, and F contamination of river water due to wastewater discharge of the Yangbajing geothermal power plant, Tibet, China
Thermal waters from the Yangbajing geothermal field, Tibet, contain high concentrations of B, As, and F, up to 119, 5.7 and 19.6 mg/L, respectively. In this paper, the distribution of B, As, and F inExpand
Water quality in the Tibetan Plateau: major ions and trace elements in the headwaters of four major Asian rivers.
Climate change is one of main determining factors on the water chemical characteristics of these headwaters of Asian major rivers in the Tibetan Plateau, and is governed mainly by difference in geological variation and regional climatic-environment. Expand
A study of arsenic, iron and other dissolved ion variations in the groundwater of Bishnupur District, Manipur, India
The presence of arsenic (As) in groundwater and its effect on human health has become an issue of serious concern in recent years. The present study assessed the groundwater quality of the BishnupurExpand
Water quality in the southern Tibetan Plateau: chemical evaluation of the Yarlung Tsangpo (Brahmaputra)
