“…Such extremely high levels of pollutants in soils can be found in many industrial sites and waste disposal dumps, which result from very localized additions or accidental spillages of highly concentrated pollutant materials (Govil et al, 1998). These elements can be leached into the surface water or ground water, taken up by plants, which later effect the human health (Acero P et al, 2003;Saether OM et al, 1997;Gough et al, 1994). The study also showed that the concentrations of the metals are to a large extent linearly correlated; Table 4 is the correlation matrix, which shows good correlation between V and Ba (r = 0.90), Cu and Co (r = 0.81), Cr and V (r = 0.78), Co and Ba (r = 0.59).…”

The pollution of soil is a source of danger to the health of people, even to those living in cities. The anthropogenic pollution caused by heavy industries enters plants then goes through the food chain and ultimately endangers human health. In the context, the knowledge of the regional variability, the background values and anthropogenic vs. natural origin of potentially harmful elements in soils is of critical importance to assess human impact. The present study was undertaken on soil contamination in Surat, Gujarat (India). The aims of the study were: i) to determine extent and distribution of heavy metals (Ba, Cu, Cr, Co, Ni, Sr, V and Zn) ii) to find out the large scale variability, iii) to delineate the source as geogenic or anthropogenic based on the distribution maps and correlation of metals in soils. Soil samples were collected from the industrial area of Surat from top 10 cm layer of the soil. These samples were analysed for heavy metals by using Philips PW 2440 X-ray fluorescence spectrometer. The data reveal that soils in the area are significantly contaminated, showing higher levels of toxic elements than normal distribution. The heavy metal loads of the soils in the study area are 471.7 mg/kg for Ba, 137.5 mg/kg for Cu, 305.2 mg/kg for Cr, 51.3 mg/kg for Co, 79.0 mg/kg for Ni, 317.9 mg/kg for Sr, 380.6 mg/kg for V and 139.0 mg/kg for Zn. The higher concentrations of these toxic metals in soils need to be monitored regularly for heavy metal enrichment.

“…The determination of natural levels of these metals is of the same importance. There are several methods to establish background values of metals (Acero et al, 2003;Celo et al, 1999;Herreweghe et al, 2003;Stercheman et al, 2000). For the background values of our study area, we have selected the method used by Celo et al (1999).…”

“…Figure 2 represents the distributions of enrichment factors of metals. Lognormal distribution plots Acero et al (2003) suggested that background values, serving as thresholds between contaminated and uncontaminated areas, could be derived from the log-distribution curves. For metal distributions in which linearity is not observed, a break-point in the curve inflection is arbitrarily fixed and the corresponding concentration is used to represent an operational threshold between contaminated and non-contaminated (or slightly contaminated) areas.…”

An assessment is presented of distribution characteristics of heavy metals in the urban topsoil from the city of Xuzhou. The concentrations of Ag, Al, As, Au, Ba, Be, Bi, Cd, Co, Cr, Cu, Fe, Ga, Hg, Li, Mn, Mo, Ni, Pb, Pd, Pt, Sb, Sc, Se, Sn, V and Zn have been determined from 21 soil samples. Examination of lognormal distribution plots indicates that the diagrams of Al, Be, Fe, Ga, Li, and V are almost linear suggesting that these metals are almost unaffected by anthropogenic activities while the plots for As, Cd, Cu, Pb, Pd, Pt, Se, Zn and others are not linear probably due to anthropogenic activities from which these metals are delivered to the soils. Al is used for mineralogical normalization of these data. An evaluation of background values for topsoil is also carried out by means of lognormal distribution plots. The results show our background values obtained from the lognormal distribution plots are comparable to those values of uncontaminated soils of Xuzhou obtained by previous work except for Cd and Hg. At present, no explanation for the exceptions Cd and Hg can be given.

“…Heavy metals are recognized as one of the major pollutants in the environment. Previous work has indicated that heavy metals migrate mainly in suspended particulates and sediments via physical and chemical adsorption on the micro-interface in the sediment -water system (Andrew et al, 2000;El-Hasand, 2001;Purohit et al, 2001;Burton et al, 2003;Davies et al, 2003;Johannesson et al, 2003;Zhang et al, 2003;Paetzel et al, 2003;Acero et al, 2003), and their potential ecological risks are decided by the distribution and contents of the metal forms and are positively correlated to the activity of the toxic metals in pore water (Zarcinas et al, 2002;Giusti, 2002;Acero et al, 2003;Sullivan, 2003).…”

Baotou City is a representative heavy industrial city in the drainage basin of the Yellow River. This paper studies the pollution of a contaminated section (Baotou section) of the Yellow River, China, with a known anthropogenic heavy metal input from the industrial discharge. The distribution of heavy metals (Cu, Pb, Zn and Cd) in the overlying water, filtered water (overlying water filtered through a 0.45-mm filter membrane) and sediments was determined in the Baotou section of the Yellow River. The results of this research indicate that heavy metal pollutants transport mostly through the carriers of suspended particulates and sediments in the fluvial environment. Baotou City's industrial discharge draining into the Yellow River from the tributaries (the Kundulun River and the Sidaosha River) increases the concentrations of Cu, Pb, Zn and Cd in the mainstream and influences heavy metals speciation. Speciation analyses show that the Cd is easily enriched in the secondary phase (bioavailable form), followed by Pb. Furthermore, based on the acute water quality criteria (WQC-Acute) and chronic water quality criteria (WQC-Chronic) set by the United States Environmental Protection Agency, the acute sediment quality criteria (SQC-Acute) and the chronic sediment quality criteria (SQC-Chronic) are calculated respectively using the developed equilibrium partitioning approach (EqP). By comparing heavy metal contents in sediments with SQC-Acute and SQC-Chronic respectively, we note that Pb and Cd have posed a high risk to the quality of water environment and to the aquatic ecosystem health of Baotou section of the Yellow River.
