“…Ni and Cu had higher values in our under-study area. Further, Pb values found by this study (mean value 11.41 mg kg -1 ) were lower than those reported by most Iranian studies conducted in various industrial areas, such as Dayani and Mohammadi (2010) (mean value 101.9 mg kg -1 ), Parizanganeh et al (2010) (mean value 128.51 mg kg -1 ) and Naimi and Ayoubi (2013) (mean value 99.4 mg kg -1 ). The mean of Cd concentrations found in our samples (0.72 mg kg -1 ) was lower than those of samples collected by other studies from industrial soils, for example, Solgi et al .59 mg kg -1 ) from grassland soils of the Angouran region in northwest Iran had higher mean values concerning Ni concentration.…”

“…Geostatistics and Geographic Information System (GIS) mapping are powerful means utilized by numerous research studies to assess pollutants' spatial distribution and behavior in urban areas (Dayani and Mohammadi 2010;Mirzaei et al 2014a, b;Nezhad et al 2015;Qishlaqi et al 2009;Solgi et al 2012). Kriging is one of the most frequently applied interpolation methods in environmental studies (Dayani and Mohammadi 2010;Hani and Karimineja 2010;Karimi Nezhad et al 2014;Mirzaei et al 2014a;Mokhtari et al 2015;Yeganeh et al 2013).…”

Spatial Eco-Risk Assessment of Heavy Metals in the Surface Soils of Industrial City of Aran-o-Bidgol, Iran

Heavy metals usually accumulate and migrate in soil environment due to human activities and this in return poses potential ecological and health risks. A total of 135 surface soil samples were collected from Aran-o-Bidgol City, Iran and were analyzed for their Cd, Pb, Ni and Cu concentrations to determine these elements' spatial distribution and potential ecological risks. To this end, interpolation mapping was conducted using Ordinary Kriging. The mean concentrations of Cd, Pb, Ni and Cu in the samples were 0.72, 11.41, 29.87 and 14.82 mg kg(-1), respectively, which were all higher than their background values. The spatial variation in the concentration of heavy metals could be attributable to point sources and vehicle emissions. Considering the severity of the potential ecological risks of metals, the descending order of contaminants' concentrations was Cd > Cu > Ni > Pb. The Potential Ecological Risk Index (RI) suggested that approximately 40 % and 59 % of the samples posed high and significantly high potential ecological risks, respectively. Moreover, ecological risk decreased progressively going from southwest to northeast over the under-study area. Considering the background values and RI, this area presented a relatively high level of contamination.

“…Road networks and industrial plants are the two main sources of heavy metal emissions in urbanized and peri-urban areas Dayani and Mohammadi 2010;Wong et al 2006). Previous studies have shown that population density, traffic volume, industrialized land use, and timing of urbanization are positively correlated with metal concentrations in surrounding soils (Argyraki and Kelepertzis 2014;Guney Responsible editor: Philippe Garrigues Summary We investigated the spatial and vertical distribution of heavy metals in soil in the Shanghai water supply area to determine the sources of contamination and the impacts of urbanization.…”

We investigated the horizontal and vertical distribution of heavy metals (Hg, Pb, Zn, Cu, Cd, As, Ni, and Cr) in soils in the water source protection zone for Shanghai to study the origins of these metals, their connections with urbanization, and their potential risk posed on the ecosystem. Determination of metal concentrations in 50 topsoil samples and nine soil profiles indicated that Hg, Pb, Zn, and Cu were present in significantly higher concentrations in topsoil than in deep soil layers. The spatial distributions of Hg, Pb, Zn, and Cu and contamination hotspots for these metals in the study area were similar to those near heavy industries and urban built-up areas. Emissions from automobiles resulted in increased soil concentrations of Cu, Pb, and Zn along roadsides, while high concentrations of Hg in the soil resulted from recent atmospheric deposition. Calculation of the potential ecological risk indicated that the integrative risk of these heavy metals in most areas was low, but a few sites surrounding high density of factories showed moderate risks.

Stocks of finite resources in the technosphere continue to grow due to human activity, at the expense of decreasing in-ground deposits. Human activity, in other words, is changing the prerequisites for mineral extraction. For that reason, mining will probably have to adapt accordingly, with more emphasis on exploitation of previously extracted minerals.This study reviews the prevailing concepts for mining the technosphere as well as actual efforts to do so, the objectives for mining, the scale of the initiatives, and what makes them different from other reuse and recycling concepts. Prevailing concepts such as "urban mining," however, are inadequate guides to the complexity of the technosphere, as these concepts are inconsistently defined and disorganized, often overlapping when it comes to which stocks they address. This review of these efforts and their potential is therefore organized around a new taxonomy based on the umbrella concept technospheric mining, defined as the extraction of technospheric stocks of minerals that have been excluded from ongoing anthropogenic material flows.An analysis on the basis of this taxonomy shows that the prevailing mining initiatives are generally scattered and often driven by environmental factors, in which metal recovery is viewed as an additional source of revenue. However, development of technology, specialized actors and new business models and policy instruments, could lead to technospheric mining operations becoming a profit-driven business.
