“…Composition of the parent material has less bearing on V content of mature, developed soils. Normal threshold value for vanadium in soils is 100 mg/kg (Larocque and Rasmussen, 1998;. Vanadium usually has a wide and varied industrial usage in dyeing, textile, metallurgy and electronics.…”

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.

“…1 Metals are introduced into aquatic systems as a result of the weathering of soils and rocks, from volcanic eruptions, and from a variety of human activities. [2][3][4] The biggest source of heavy metal pollution is known to be industrialization. 5,6 Furthermore, high concentrations of heavy metals enter the aquatic system by release of industrial cooling water into rivers, dumping of sewage sludge, and through wet and dry deposition.…”

Recebido em 27/4/11; aceito em 16/9/11; publicado na web em 8/11/11 This work studies the effect of NTMP (nitrilotris(methylenephosphonic acid)) on the adsorption of Cu(II), Zn(II), and Cd(II) onto boehmite in the pH range 5-9.5. The data were analyzed using the 2-pK constant capacitance model (CCM) assuming ternary surface complex formation. Under stoichiometric conditions, NTMP is more effective for removing Cu(II) than Zn(II) from solution and the contribution of ternary surface complexes are important to model the adsorption of both metals. Under nonstoichiometric conditions and high surface loading with a Me(II)/NTMP ratio of 1:5, Cu(II) and Zn(II) adsorption is significantly suppressed. In the case of Cd(II) the free metal adsorption is the most dominant species.

“…The transfer of contamination and its dispersion in the aquifer is a very slow process and changes in metal concentration in the upper aquifer layers are not manifested in a short time either. Overdoses of copper may also lead to neurological complications, hypertension, liver, and kidney dysfunctions (Larocque and Rasmussen 1998;Rao et al 2001;Krishna and Govil 2004). The concentration of nickel ranges from 1.6-147.0 μg/l in the study area with an average of 36.7 μg/l.…”

Ranipet industrial area is about 120 km from Chennai on Chennai-Bangalore highway and is a chronic polluted area identified by Central Pollution Control Board of India. It is one of the biggest exporting centers of tanned leather in India. The total number of industries located in and around Ranipet town are 240 tanneries along with ceramic, refractory, boiler auxiliaries plant, and chromium chemicals. Studies were carried out to find out the contamination of surface water bodies due to industrial effluents. The results reveal that the surface water in the area is highly contaminated showing very high concentrations of some of the heavy/toxic metals like Cadmium ranging from 0.2 to 401.4 microg/l (average of 51.1 microg/l), Chromium 2.4-1,308.6 (average of 247.2 microg/l), Copper 2.1-535.5 microg/l (average of 95.5 microg/l), Nickel 1.6-147.0 microg/l (average of 36.7 microg/l), Lead 6.4-2,034.4 microg/l (average of 467.8 microg/l) and Zinc 20.8-12,718.0 microg/l (average of 3,760.4 microg/l). The concentration levels of these metals are much above the permissible limits in surface water and are health hazards especially for the people working in the tannery industries. It was observed that the people in the area are seriously affected and suffering from occupational diseases such as asthma, chromium ulcers and skin diseases. Distribution of metals, their contents at different locations, and their effects on human health are discussed in this paper.
