Abstract It is imperative to understand the pollution of potentially toxic elements (PTEs) in different soils in order to determine the sustainable management approaches for soils. Potentially toxic elements (Fe, Mn, As, Pb, Zn, Ni, Cu, Cn, Co and Cd), and pH and organic carbon were determined in agricultural, non-agricultural and industrial soils of Indian, Punjab. The findings of PTEs indicated that industrial soils recorded highest concentration of PTEs followed by non-agricultural and agricultural soils. The percentage change recorded from agricultural to non-agricultural soils for PTEs were 3.19% for Fe, 25.3% for Mn, 63.8% for Cu, 13.5% for Cn, 49.8% for Pb, 79.6% for Ni, 35.8% for Co and 32% for Cd. From non-agricultural to industrial soils the percentage change observed for PTEs were 89% for Zn, 2.03% for Fe, 21.9% for Mn, 68.2% Cu, 9.2% for Cn, 35.8% for Pb, 18.4% for Co, 30.4% for Cd and 43.4% for As. The results of contamination factor, enrichment factor, geoaccumulation index, pollution and modified pollution indices indicated that Cd and As showed severe contamination in all studied soil types. Ecological risk assessment results revealed that Cd exhibited very risk in different soil types. The outcomes of this study will aid in forming approaches to decline the perils allied with PTEs in soils, and produce guidelines to save the environs from long term accrual of PTEs.

Different Soils

Mining is an essential activity for obtaining materials necessary for the well-being and development of society. However, this activity produces important environmental impacts that must be controlled. More specifically, there are different soils near new or abandoned mining productions that have been contaminated with potentially toxic elements, and currently represent an important environmental problem. In this research, a contaminated soil from the mining district of Linares was studied for its use as a raw material for the conforming of ceramic materials, bricks, dedicated to construction. Firstly, the contaminated soil was chemically and physically characterized in order to evaluate its suitability. Subsequently, different families of samples were conformed with different percentages of clay and contaminated soil. Finally, the conformed ceramics were physically and mechanically characterized to examine the variation produced in the ceramic material by the incorporation of the contaminated soil. In addition, in this research, leachate tests were performed according to the TCLP method determining whether encapsulation of potentially toxic elements in the soil occurs. The results showed that all families of ceramic materials have acceptable physical properties, with a soil percentage of less than 80% being acceptable to obtain adequate mechanical properties and a maximum of 70% of contaminated soil to obtain acceptable leachate according to EPA regulations. Therefore, the maximum percentage of contaminated soil that can be incorporated into the ceramic material is 70% in order to comply with all standards. Consequently, this research not only avoids the contamination that contaminated soil can produce, but also valorizes this element as a raw material for new materials, avoiding the extraction of clay and reducing the environmental impact.

AbstractPotentially toxic elements (PTEs) pollution has become a serious environmental threat, particularly in developing countries such as China. In response, there is a growing interest in phytoremediation studies to identify plant species as designated hyperaccumulators of PTEs in polluted soils. Poinsettia was selected as a candidate species for phytoremediation of six PTEs (Zn, Pb, Hg, Cr, As, Cu) in this study. A pot cultivation experiment (randomized incomplete block experimental design with 5 treatments and 4 blocks) was conducted using contaminated soils gathered from an industrial area in southcentral China. The bioaccumulation factor (BAF), translocation factor (TF), and bioconcentration factor were analyzed to determine the phytoremediation potential of poinsettia potted in different ratios of polluted soils. One-way ANOVA with post-hoc Tukey’s test showed that poinsettia had significant uptake of Zn, Pb, Cu (BAF < 1 and TF < 1, p < 0.05) and Hg (BAF < 1 and TF > 1, p < 0.05). Poinsettias can therefore effectively accumulate Zn, Pb, and Cu in their lateral roots while extracting and transferring Hg into their leaves. Moreover, poinsettia exhibited tolerance towards As and Cr. Interestingly, it was also observed that PTEs can inhibit the height of potted poinsettia at a certain concentration.

AbstractThis geochemical study explored the distribution of potentially toxic elements (PTEs), such as As, Cd, Co, Cr, Cu, Ni, Pb, Sb, Tl, U, and Zn, along soil profiles of a metallurgical and industrial area in Kosovo, with the aim of assessing geochemical background and contamination threshold of PTEs in soil, and defining surface and vertical level and extent of soil contamination by PTEs. The geochemical background was assessed by exploratory data analysis of PTE concentrations in soil profiles. The upper limit of geochemical background (contamination threshold) was used as reference value to calculate the single pollution index and establish the PTE contamination level. Cadmium, Pb, Sb, Zn were the primary soil contaminants and As, Cu, Tl the secondary ones. The main sources of soil contaminants were the Zvecan smelter for Pb, Sb, As, Cu, Tl, and the Trepca industrial complex for Cd and Zn. The highest levels of Pb and Sb contamination were found up to depths between 30 and 60 cm in soil profiles within 5 km north and south-east of the Zvecan smelter. Contamination by Pb and Sb decreased with depth and affected the whole thickness of soil profiles closer the smelter. Cadmium and Zn contamination declined with distance from the Trepca industrial complex and decreased with depth, extending down to depths of 40–90 cm and 30–70 cm, respectively. Anomalous natural concentrations of Co, Cr, and Ni were found in soils collected in the northern part of the study area, where the geology consists mainly of ultrabasic and basic magmatic rocks.

Ecological Requirements

Toxic elements in coal are one of the main sources of environmental pollution. Their content in coal is quite high, therefore the modern raising of ecological requirements needs taking into account the influence of coal-mining enterprises on state of environment. This causes the need of new scientifically grounded methods for forecasting the content of toxic and potentially toxic elements (TaPTE) in rock mass, as well as in mining waste and coal enrichment. In the article, the results of investigations of TaPTE in coal seam c8H of "Blagodatna" mine field of Pavlohrad-Petropavlivka geological and industrial area of Donbas are considered, for the purpose of establishing regularities in their spatial distribution. The average content and lateral variations of TaPTE concentrations in coal seam were established, maps of the isoconcentrate of TaPTE and maps of the regional constituent of their contents in the area were constructed. The constructed maps are the factual basis for the long-term forecast of the concentrations of TaPTE in the rock mass extracted from mines. Linear regression equations are calculated, they characterize relationship between the concentrations of toxic and potentially toxic elements and the main technological parameters of the investigated layer. These equations can be used for short-term and mediumterm forecasting of TaPTE content in the extracted rock mass. In its turn, such forecasts should serve as the basis for technological solutions aimed at reducing their content in products and waste of coal enrichment. In addition, analysis of the result of statistical processing of geochemical information and geological and structural characteristics of the seam c8H of mine field of "Blagodatna" mine indicates that the formation of the association of Co-Ni-V-Pb-Cr-Mn is associated with the enrichment of contact zones of the coal layer by these elements with thickness of 0,15-0,20 m. The association of Hg and As is due to their genetic connection with the sulfide mineralization of fractured zones of tectonic nature.

Samples of Jatropha curcas, a non-edible biodiesel plant, which tolerates harsh environments was collected from an industrial area with high anthropogenic activities (Challawa Industrial area, Kano, Nigeria)and sorted into leaves, stems and roots. The aim is to assess the potentials of Jatropha curcas in accumulation and translocation of six Potentially Toxic Elements (PTEs) (Zn, Cu, Cd, Cr, Pb and Ni) from the soil media. Atomic Absorption Spectroscopy (AAS) was used to assess the concentrations. The bioaccumulation/ transfer of metals from roots to shoots and from soil to roots were evaluated in terms of translocation (TF) and bioconcentration factor (BCF). TF values of 1.02, 4.92, 2.68, 3.73, 1.5 and 3.19 for Zn, Cu, Cd, Cr, Pb and Ni respectively indicate that J. curcas was efficient in translocation of PTEs from roots to shoots. This is an indication that the plant is therefore suitable for phytoextraction of Zn, Cu, Cd, Cr, Pb and Ni. But CF value of 0.66 and 0.70 for Cu and Pb on the other hand shows that J. curcas is less able to translocate these two metals (Cu and Pb) indicating ineffective transfer. This show that J. curcas may be suitable a candidate for phytostabilization of Copper and lead in contaminated soils in the study area.
