摘要:150 water samples were collected to asses weathering and anthropogenic Controlson water chemistry of Wular Lake-India. The results revealed lake waters are Alkine innature. The order of major cations and anions was Ca2+>Mg2+>Na+>K+ and HCO3->SO42->Cl-, respectively further reveals three chemical water types are present: Mg-HCO3, CaHCO3and Hybrid-type. The geochemical processes suggested that chemical compositionlake water is mostly influenced by the lithology of the of basin (carbonates, silicates andsulphates) which had played a significant role in modifying hydro-geochemical facies in theform of Ca–HCO3, Mg–HCO3 and hybrid type. Correlation coefficient matrix for the majorions of water samples shows high positive and significant relation between Ca2+, Mg2+ andHCO3-; Ca2+ and Hardness suggesting carbonate lithology as source of ions mainly comingthrough dissolution of calcite. A positive relationship between Mg2+ and HCO3-; Mg 2+ andHardness indicate some contribution coming through dissolution of dolomite as well.Moreover, a positive and significant correlation between Na+and Clcannotbe related solelyto the dissolution of soil- salts, a significant contribution may be furnished fromanthropogenic sources in the form of domestic wastes, evaporation, thereby increasing thesalinity of Wular waters. The positive correlation of K+, Na+, SO42- and Cl- with NO3-;manifested the possible anthropogenic inputs from agricultural activities and domesticwastes.
