In order to establish the natural processes and geochemical factors responsible for enrichment of trace metal ions (Cu, Co, Ni, Zn and Cr) with respect to textural parameters (sand, silt and clay weight percentages) along with depth, multivariate statistical approach has been carried out for sediments in different water zones of Chilika lake, the largest(More)
In the present study, concentration of some selected trace metals (Fe, Mn, Ni, Co, Pb, Zn, Cu, Cr and Cd) are measured in Brahmani, Baitarani river complex along with Dhamara estuary and its near shore. Chemical partitioning has been made to establish association of metals into different geochemical phases. The exchangeable fraction is having high(More)
The particle size distribution, geochemical composition and sequential leaching of metals (Fe, Mn, Ni, Cu, Co, Cr, Pb, Zn and Cd) are carried out in core sediments (<88 microm) from the Brahmani and Nandira Rivers, India. To confirm the contamination of downstream sediments by fly ash, mineralogical and morphological characterizations were carried out. High(More)
Spatial and temporal distributions of water quality using multivariate statistical techniques for the evaluation of nutrients (NO(2)-N, NO(3)-N, NH(4)-N, PO(4)-P, SiO(4)-Si, total N, total P) in relation to some physico-chemical features (DO, BOD, TSS, TDS, SO (4) (2-) , Cl(-)) were studied for 31 different stations of the Mahanadi river-estuarine system in(More)
