“…The two-factor ANOVAwas performed to examine the influence of different sampling sites and flow periods on dissolved trace elements, physicochemical parameters, and their interaction effects (Hatje et al 2003;Mendiguchía et al 2007). Normality and homogeneity of variances were evaluated using the one-sample Kolmogorov-Smirnov and Levene's tests, respectively.…”

“…There have been many studies that have investigated the geochemical processes of dissolved trace elements (Shiller andBoyle 1985, 1987;Neal et al 1997;Zwolsman et al 1997;Ramessur et al 2001;Ravichandran 2003;Chaudry and Zwolsman 2008) as well as the sources of the pollution (Morales et al 1999;Hatje et al 2003;Pekey et al 2004; Kuppusamy and Giridhar 2006;Mendiguchía et al 2007;Zhou et al 2007). These complex physicochemical processes are controlled by many factors, such as riverine input, precipitation, pH, temperature, oxygen, nutrients, chemical sorption-desorption, and (Zwolsman et al 1997;Zhou et al 2003;Caccia and Millero 2003;Hatje et al 2003;Chaudry and Zwolsman 2008), which determine the addition and removal of dissolved trace elements in the riverine systems.…”

Dissolved trace elements and physiochemical parameters were analyzed to investigate their physicochemical characteristics and identify their sources at 12 sampling sites of the Jinshui River in the South Qinling Mts., China from October 2006 to November 2008. The two-factor ANOVA indicated significant temporal variations of the dissolved Cu, Fe, Sr, Si, and V (p<0.001 or p<0.05). With the exception of Sr (p<0.001), no significant spatial variations were found. Distributions and concentrations of the dissolved trace elements displayed that dissolved Cu, Fe, Sr, Si, V, and Cr were originated from chemical weathering and leaching from the soil and bedrock. Dissolved Cu, Fe, Sr, As, and Si were also from anthropogenic inputs (farming and domestic effluents). Correlation and regression analysis showed that the chemical and physical processes of dissolved Cu was influenced by water temperature and dissolved oxygen (DO) to some degree. Dissolved Fe and Sr were affected by colloid destabilization or sedimentary inputs. Concentrations of dissolved Si were slightly controlled by biological uptake. Principal component analysis confirmed that Fe, Sr, and V resulted from domestic effluents, agricultural runoff, and confluence, whereas As, Cu, and Si were from agricultural activities, and Cr and Zn through natural processes. The research results provide a reference for ecological restoration and protection of the river environment in the Qinling Mts., China.

“…In Spain, some rivers have higher Ni concentrations, for example, the Guadalquivir river in Andalusia with 2.31 mg L x1 (Mendiguchı´a et al, 2007), others are more contaminated by metals, so is the case of rivers Odiel and Tinto (163 and 170 mg L x1 , respectively) discharging its waters into the Huelva estuary in Andalusia (Ca´novas et al, 2009) or Meca River in Huelva with 252 mg L x1 (Galva´n et al, 2009). Similarly, many rivers in different places in the world have higher concentrations of metals in the water.…”

-Suspended sediment transportation and associated pollutants from catchment to stream networks are responsible for aquatic habitat degradation, reservoir sedimentation and the transportation of sediment bound pollutants. Quantifying suspended sediment loads from lands to watercourses is essential in controlling soil erosion and in implementing appropriate mitigation practices to reduce stream sediment and associated pollutant loads, and hence improve surface water quality downstream.The main objective of this study is to evaluate the temporal variability of hydrology, sediment and nickel loads using Soil and Water Assessment Tool in Oka watershed located in north Spain. Model simulation was completed using 11 years historical records (2001-2009 for validation and 2009-2012 for calibration) of streamflow and suspended sediment concentration (SSC). Thestreamflow, SSC and sediment load estimated from the model were compared with observed data using statistical parameters, which indicates a successful simulation. The annual production of simulated sediments shows variability between 662 and 1515 t, with a mean specific yield of 33 t km x2 y x1 . The annual load of nickel simulated ranged from 32 to 72 kg, representing a mean specific of 1.63 kg km x2 year x1 . The information obtained from this research is of interest to understand long term interannual variability of suspended sediment and nickel yield.

“…Natural environment has the ability to sequester these heavy metals but whenever the waste exceeds the environmental tolerance levels, specific effects are noticed in man. The leaching of waste rich in heavy metals, discharge of industrial effluents or dumping of waste rich in heavy metals into aquatic systems frequently cause critical pollution levels to be exceeded (Mendiguchia et al 2007). For example, lead and cadmium are commonly found in the wastewater of industries such as electroplating, plastic and paint manufacturing, mining, metallurgical process, petrochemical process, batteries, paper and pulp (Iqbal and Edyvean 2005).…”

The elemental composition of termite mound was determined by XRF which revealed K, Ti and Mn as minor constituents while Ca and Fe as major constituents. The DG value for Zn(II) is positive in both single and binary systems, while that for Pb(II) was positive between 313-333 and 323-333 K for single and binary systems, respectively. The data show that the use of neglected termite mound for Pb(II) and Zn(II) removal from aqueous solutions is economically significant in wastewater treatment.
