“…As a consequence, elevated levels of heavy metals and other mining-related pollutants (cyanides, phosphorus) have been detected in the water and sediments of the Selenga and its tributaries, as well as floodplain soils and groundwater (Battogtokh et al 2014;Brumbaugh et al 2013;Chalov et al 2015;Inam et al 2011;McIntyre et al 2016;Nadmitov et al 2014;Pavlov et al 2008;Pfeiffer et al 2015;Stubblefield et al 2005;Thorslund et al 2012). Even though contaminant transport towards the Selenga delta does take place (Chalov et al 2015;Khazheeva et al 2004;Karthe et al 2014), it should be noted that contaminations currently have the largest effects in local hot spots (Hofmann et al 2010;Inam et al 2011;Pfeiffer et al 2015). Currently, there are different views regarding their impact on Lake Baikal itself (Chebykin et al 2010;Pavlov et al 2008).…”

“…The protection of Lake Baikal and the planning of water management measures in the Selenga river basin require a good understanding of current trends regarding hydrology, water quality, aquatic and riparian zone ecology of the Selenga and its key tributaries , and geoand biochemical processes governing the ecological functioning of the Selenga delta (Khazheeva et al 2004). The following anthropogenic impacts constitute threats to the ecology of the Selenga from its tributaries down to its delta:…”

“…Table 1 shows the levels of metals in water from Henan reaches of the Yellow River. It is generated by comparing measured concentration of metals with world average background levels [14] and water quality standards currently effective in USA and China [15,16], and the results are obtained from the literature [9,[17][18][19]. In China the water bodies are divided into five classes according to the utilization purposes and protection objectives: Class I is mainly applicable to the water from sources, and the national nature reserves.…”

Metals in water and surface sediments from Henan reaches of the Yellow River, China

et al. 2010

The concentrations of Cd, Cr, Cu, Ni, Pb and Zn were determined in the water and surface sediments from the Henan reaches of the Yellow River. Twenty-three sampling sites along the Yellow River and its tributaries were selected. Generally, metal concentrations were found to decrease in sequences of Zn > Cu > Pb > Cr > Ni > Cd in water and Zn > Cr > Pb > Ni > Cu > Cd in sediments. High levels of metal concentration were determined at a few stations of the river and its tributaries, such as Yiluo River, Si River and Qin River. The pollution of the Yellow River by Cd, Cr, Cu, Ni, Pb and Zn can be regarded as much higher compared to the background values, US EPA criteria (1999) and China water quality criteria (2002). For sediments, metal levels except Pb did not significantly exceed the average shale levels and backgrounds in several countries including China. Data analysis manifests that positive correlations were found between Cu, Ni and Zn in water, and Pb, Ni, Zn and Cr in sediments. The Pearson correlation coefficient analysis and Cluster analysis were provided to assess the possible contamination sources.The results indicate a general appearance of serious pollution along the banks of the Yellow River. The wastewaters discharged by the mine plants, smelter plants, power plants, battery plants, tannery plants, etc., and sewage inputs from the cities along the river banks may be the sources of metals. metals, water, surface sediment, Yellow River

Conservation of water quality is inherently tied to watershed management. Efforts to proect Lake Baikal have increasingly focused on the Selenge River, a major tributary, with more than half its watershed area in Mongolia. Placer gold mining in Mongolia has the potential to load total suspended sediment (TSS), and total phosphorus (TP) into Lake Baikal and destroy spawning areas for the endangered Taimen salmon (Hucho taimen taimen). This work describes water quality assessments performed from 2001 to 2003 on Mongolian tributaries to the Selenge River. Of 7 rivers sampled, rivers with proximal mining had the worst water quality. Elevated loading of TSS and TP was observed below mining regions on the Tuul River. Flooding could breach thin strips of land separating dredge pits from river channels, resulting in massive sediment loading. Extensive disturbance of the river terrace was apparent for many square kilometers. In the mountainous headwaters of the Yeroo River, tributary drainages undergoing mining had TP concentrations 8 to 15 times higher than the main stem. TSS was 7 to 12 times higher, and turbidity was 8 times higher. Alternative mining technologies exist that could minimize impact and improve the possibility for reclamation.
