摘要: To study the water quality across Himalayan region, a total of 43 river samples were collected in September 2012 from Yarlung Tsangbo (Brahmaputra), Indus and Ganges basins. We measured common parameters (pH, EC, TDS, temperature) analyzed element concentrations (As, Cr, S, Sr, Tl, B, Ba, Ca, Al, Fe, K, Mg, Mn, Na, Rb, Ti) using ICP-AES. The results show that all rivers have an alkaline environment with pH 7.9 to 8.9. TDS has positive relationship Ca Mg concentrations. elemental contents are comparable among different enrichment factor As Himalayas showed high value at 30, indicating impacts anthropogenic activities. this region is under influence climate change on glacier melting, which will affect chemistry seasonal discharge runoff.
