“…The contamination of surface water by heavy metals is a serious ecological problem as many heavy metals such as Hg, As, Pb, Sb, Ni, Sr and Cd are toxic even at low concentrations. They are non-degradable and can accumulate in the human body and causing damage to nervous system and internal organs [38,39]. Though some metals such as Cu, Fe, Mn and Zn are essential as micronutrients for living organisms, they can be detrimental to their physiology at higher concentrations [40,41].…”

“…Some of the metals like Cu, Fe, Mn, Ni and Zn are essential as micronutrients for the life processes in animals and plants while many other metals such as Cd, Cr, Pb and Co have no known physiological activities (Kar et al, 2008;Suthar and Singh, 2008;Aktar et al, 2010). Metals are non-degradable and can accumulate in the human body system, causing damage to nervous (Lee et al, 2007;Lohani et al, 2008). However, the rivers play a major role in assimilation or transporting municipal and industrial wastewater and runoff from agricultural and mining land (Singh et al, 2004).…”

ABSTRACT:The objective of the study is to reveal the seasonal variations in the river water quality with respect to heavy metals contamination. To get the extend of trace metals contamination, water samples were collected from twelve different locations along the course of the river and its tributaries on summer and the winter seasons. The concentrations of trace metals such as cadmium, cromium, copper, cobalt, iron, manganese, nickel, lead, mercury and zinc were determined using atomic absorption spectrophotometer. Most of the samples were found within limit of Indian drinking water standard (IS: 10500). The data generated were used to calculate the heavy metal pollution index of river water. The mean values of HPI were 36.19 in summer and 32.37 for winter seasons and these values are well below the critical index limit of 100 because of the sufficient flow in river system. Mercury and chromium could not be traced in any of the samples in the study area.

Metals are non-degradable and can accumulate in the human body system, causing damage to nervous system and internal organs (Lee et al, 2007;Lohani et al, 2008). They enter into river water from mining areas through various ways such as mine discharge, run-off, chemical weathering of rocks and soils, wet and dry fallout of atmospheric particulate matter Bird et al, 2003;Kraft et al, 2006;Venugopal et al, 2009) or from industrial areas via discharge of untreated industrial effluent in the river .…”

In this study, metal pollution index (MPI) and principal component analysis (PCA) techniques were applied to water quality data sets obtained from River Chanchaga, Minna, North-central Nigeria, to obtain the spatial and temporal changes in the river quality. Results show that the indices which changed the quality of the river water consist of natural (weathering and bedrock dissolution) and anthropogenic activities such as mining, agriculture, domestic and industrial wastes within its catchment. The result of the MPI indicates that the river is slightly affected with respect to heavy metal pollution, which can be attributed the gold mineralization and mining along the river course. Five principal factors were generated when the data was subjected to PCA and they correspond to five possible point source of pollution to the river. Factors 1 and 2 are naturally induced while factors 3, 4 and 5 are due to anthropogenic interference in the hydrological cycle. Although, the river quality does not pose any serious threat to human health presently, the various anthropogenic activities domiciled at the downstream should discontinue, in order restore the river water quality. The people living close to the river should adopt a good sanitary habit by not dumping waste into the river henceforth. Boiling of the water before consumption is advocated.
