“…The minimum pH (7.11 ± 0.03) was found at station H3 during the summer and the maximum (7.44 ± 0.03) at station H2 during the summer also. This is in contradiction to the findings of Baruah et al (1996) who reported higher pH during the rainy season. Rao et al (1998) recorded higher pH values in the summer season.…”

“…Similar findings have also been reported for the sediment of Narmada River and Kolleru Lake (Jain et al, 2007;Sekhar et al, 2003, respectively). The sediment of Jhangi River was between acidic and neutral with a pH range from 3.5 to 6.7 (Baruah et al, 1996). Jain (2004) reported the sediment of Yamuna River as alkaline (pH between 8.01 and 8.45).…”

“…Although the importance of metal speciation and fractionation has long been realised, it has not been investigated sufficiently in India. Some studies have been done on the fractionation of metals in Indian rivers and lakes (Baruah et al, 1996;Khwaja et al, 2001;Sekhar et al, 2003;Jain, 2004;Singh et al, 2005;Ayyamperumal et al, 2006;Jain et al, 2007;Krupadam et al, 2007;Purushothaman and Chakrapani, 2007), but none have been conducted on the fractionation of metals in Indian reservoir sediment.…”

Sediments of a polluted reservoir were evaluated for total contents of Cd, Cr, Cu, Ni, Pb and Zn along with their different geochemical forms (exchangeable, carbonate, Fe-Mn, organic matter and residual). Mineralogy of the sediments and physico-chemical parameters i.e. pH, OC and percentage of sand, silt and clay were also evaluated to see the dependency of heavy metals concentration on these parameters. The total concentration of heavy metals in the sediments varied according to sites and seasons. Except for station H1 which had moderately higher concentration of Cu (45.5 mg kg -1 ), concentrations of all other metals at all the sites under study were below the standard shale value. Maximum proportions of all metals were associated with the carbonate and residual fractions. The Risk Assessment Code showed a low risk for Cr, Ni and Zn, and a medium risk for Cu at station H3 and H4. On the basis of freshwater sediment quality guidelines, there is a strong possibility of Cr and Cu toxicity for aquatic biota of the reservoir. The data were further processed using Pearson's correlation and factor analysis to obtain more accurate information about the behaviour of these metals. A positive relationship among the metals confirmed the anthropogenic sources of pollution in the reservoir. Significant positive relationships of heavy metals with the texture of the sediment were also obtained.

“…A similar phenomenon has been noted in the case of lake waters under the influence of a copper smelter (Lubin, Poland) [33]. Significantly higher bottom sediment pollution with heavy metals rates were recorded for surface waters strongly influenced by urbanised industrial areas, for instance petroleum refineries in Greece, India, Cameroon, and Turkey [35][36][37][38][39]. Higher metal contents in sediments were also observed in the Gomti River in the Ganges catchment in India, with low metal concentrations in water [24].…”

Environmental pollution influences all environmental components: air, precipitation, surface water, groundwater, and soil. Between these elements constant exchange and penetration by chemicals occurs. Their sources are natural and anthropogenic. The quantity and quality of these contaminants are varied and depend on a number of factors.Respect for its natural geographical location, terrain, geological structure, the presence of water reservoirs, and open spaces is important. The distortion of the natural landscape by people introduces more or less visible changes. However, they are not neutral to the environment. These changes result in alterations to the composition of air, water, and soil. This is done both at a low and a high degree of contamination and reduces the accumulation of chemical condition of the environment.Pol. J. Environ. Stud. Vol. 24, No. 5 (2015), [2167][2168][2169][2170][2171][2172][2173][2174][2175] AbstractOur study was conducted in the area of the Parseta and Radew rivers in 2012 and 2013. Samples were taken of water and bottom sediments. In terms of their physico-chemical composition, the tested waters can be characterized as slightly polluted. In terms of zinc and copper concentrations, the waters belong to purity class I, but the contents of cadmium, lead, and nickel exceed the Proposed Environmental Quality Standards for Priority Substances.As far as copper, nickel, zinc, and cadmium are concerned, the studied sediments were not polluted, and the geo-chemical index values were within class I. The relevant accumulation rates for metals in sediments can be ordered as follows: Cd

“…The Tessier scheme divides metals into five fractions: (1) exchangeable, (2) carbonate-bounded, (3) ironmanganese oxides-bounded, (4) organic matter-bounded, and (5) residual. In spite of long analysis times (days), many studies have been carried out using this method (Baruah et al, 1996;LopezSanchez et al, 1996;Ginepro et al, 1996;Pempkowiak et al, 1999). Fraction 1 is considered to be the most soluble/bioavailable and the last fraction the least bioavailable or nonanthropogenic (Chapman et al, 1998;Fichet et al, 1998;Rieuwerts et al, 1998;Langston et al, 1999;Mehra et al, 1999).…”

After determination of total heavy metal concentrations in Tigris river sediments, a Tessier sequential extraction technique and a modified form using a microwave heating procedure were applied. Recoveries of total heavy metals from the sediment samples using the microwave and conventional techniques were reasonably comparable, in spite of a big difference in time required. 44-46% of Co, 24-36% of Cu, 69-81 % of Ni, and 55-73% of Zn were found in the residual fraction (i.e. not bioavailable).
