“…Hydrochemistry is a function of natural factors, such as climate, geology, topography, and weathering of rocks and anthropogenic activities including industrial and agricultural activities, and domestic waste (Kumarasamy et al 2013; Thomas et al 2014). In addition, studies on hydrochemistry of rivers provide vital information on the sources of major chemical signatures, the environmental change, and on weathering processes and associated CO 2 consumption in a catchment (Dalai et al 2002;Li et al 2011).…”

The study focuses on the chemical compositions of the river waters in the middle and upper reaches of the Yarlung Tsangpo river system. Samples were collected in two periods along the river system to analyze the spatiotemporal variation characteristics and to determine the weathering processes and CO 2 consumption. The results show that the chemical facies of river waters are dominated by Ca-HCO 3 type and the TDS values cover a wide range of 98.2-619.8 mg/l with an average value of 268.6 mg/l, which is higher than that of the global river waters. There are three major reservoirs (carbonates, evaporites, and silicates) contributing to the major ions, and the predominances of the reservoirs of different rivers show spatial heterogeneity. The chemical weathering rates of silicates and carbonates are 3.43 and 4.49 t/km 2 /year, respectively. Overall, the middle and upper reaches of Yarlung Tsangpo are responsible for 0.3 and 0.16 % of global atmospheric CO 2 consumption by silicates (1.7 9 10 5 mol/ km 2 /year) and carbonates (1.27 9 10 5 mol/km 2 /year), respectively. In addition, the chemical weathering fluxes of the catchments consume atmospheric CO 2 of 0.5456 Tg C/year, accounting for 0.14 % of the total organic carbon flux to the oceans by rivers globally.

“…These technique provides information on the most meaningful parameters, which describe whole data set with minimum loss of original information. It helps in pattern recognition that attempts to explain the variance of set of inter-correlated variables and transforming into a smaller set of independent variables [20,21,30,31,33].…”

“…In the assumption FA reduces contribution of less relevant variables obtained during the extraction of data by the PCA. The main difference between the PCA and FA is that the FA allows the expression of the measured values as a combination of factors and the equation includes a term, and thus obtained varifactors (factors after varimax rotation) may comprise previously unobservable hidden variables [18,20,30,31,35,36].…”

Water quality of the Glebokie Lake in Szczecin (NW-Poland) was studied in years 2012-2014. Glebokie Lake is a reservoir with a negative water balance related to the location draining groundwater drinking water intake for Szczecin agglomeration. In 2004 hydrotechnical regulations were conducted aimed at maintaining a constant amount of water in the lake, which involved a temporary feeding Glebokie Lake with Gunica River waters. In order to determine the hydrochemical status of the Lake waters and the factors shaping water quality -19 water quality indices within 25 months were measured: temperature, pH and water oxygen status, nutrients (N, P) and ionic macrocomponents and Fetot. Trophic status of the lake waters using the Carlson criteria was defined. On the basis of chemometric analysis of measurement data (CA, PCA/FA and DA) we established that statistically significant factors affecting water quality in the study period were: seasonal (the climatic seasons) changes in the biological processes activity, periodical (in April and November) waters inflows from the Gunica River, anthropopressure in during swimming season and the coagulant (FeSO4) presence in the ecosystem. The possibility of applying the chemometric techniques to interpret measurement data in the lake type like Glebokie Lake with a small amount of data has been shown.

Monitoring the surface run-off and physicochemical parameters of a river on a regular basis provides valuable information on the eco-hydrologic conditions of the river basin. The resultant data provide valuable insights into spatial and temporal variation on water quality, considered as a measure of the health of a river. The physicochemical characteristics of any aquatic ecosystem and the nature and distribution of its biota are directly related to and influenced by each other and controlled by a multiplicity of natural regulatory mechanisms. The River Tamiraparani, a perennial river in southern India was studied for comprehensive environmental issues. The major ion chemistry and nutrients of the studied samples show seasonal and spatial variations, under the predominant influence of geogenic (natural weathering) and to certain extent, lesser influence of anthropogenic sources. Application of various geochemical indices (SAR, RSC, PI, PS and Na %) and plots revealed that, a majority of the samples (90 %) are within the permissible limits of the domestic and agricultural usages. The occurrences of organochlorine compounds in the studied samples suggest influx from agricultural activities.
