“…We found a slight Zn enrichment in CHA, RTE, SUM and YOC, which could have been associated with a natural pedogenic input (CHA) and anthropogenic activities (RTE, SUM and YOC). Our findings are in agreement with other studies that related topsoil Zn content to cement plants (Adejumo et al 1994;Al-Khashman and Shawabkeh 2006;Bermudez et al 2010). Moreover, we found similar results to previous biomonitoring studies performed in Córdoba using Usnea amblyoclada and R. celastri that reported high Zn concentrations in industrial areas (Bermudez et al 2009;Carreras and Pignata 2002;Jasan et al 2004).…”

“…Related to this, biomonitoring studies on the air pollution performed in Córdoba have found the anthropogenic input of Cu to be associated with agricultural and industrial activities Pignata et al 2002). Our findings are similar to those of Al-Khashman and Shawabkeh (2006) and Bermudez et al (2010), who found Cu topsoil enrichment around cement plants in Jordan and Yocsina, respectively. Carreras and Pignata (2002) also assessed that the cement plant and the industrial waste incinerator in YOC were air pollution sources of Cu.…”

“…Several studies have assessed that cement plants produce an input of metals and metalloids such as As, Cd, Ca, Co, Cr, Cu, Ni, Pb, and Zn (Adejumo et al 1994;Al-Kashman and Shawabkeh 2006;Işikli et al 2003Işikli et al , 2006Schuhmacher et al 2002Schuhmacher et al , 2004Schuhmacher et al , 2009). In Yocsina, Bermudez et al (2010) assessed the input of lithogenic-related elements and Cu, Pb, and Zn from a cement plant and an industrial waste incinerator on topsoils along a 7 km transect. It is worth noting that industrial waste incinerators are important sources of heavy metal and organic compound pollution (Anderson et al 2010;Chang et al 2008), with some of the heavy metals emitted by these industries being toxic for human and plants, even at low concentrations (Kabata-Pendias and Mukherjee 2007).…”

“…Soil behaves as a sink of heavy metals by aerial deposition of particles emitted by urban and industrial activities (Al-Khashman and Shawabkeh 2006;Bermudez et al 2010;Chen et al 2008;Fabietti et al 2010), vehicle exhausts (Hernandez et al 2003;Manta et al 2002), agricultural practices Fabietti et al 2010;Facchinelli et al 2001;Micó et al 2006), etc. Although soil metal pollution is traditionally assessed in terms of total or pseudototal element concentrations, it is well known that the hazard that potentially toxic metals represent to living organisms is determined to a much greater extent by their chemical forms than by their total concentrations (Lavado et al 2007;Madrid et al 2007;Sutherland et al 2004). Therefore, several different reagents have been proposed in the literature to estimate metal availability by means of a single extraction.…”

Purpose Heavy metals are especially dangerous because of their persistence and toxicity. Soil behaves as a sink of heavy metals by aerial deposition of particles emitted by different human activities. The aims of this work were to identify the levels and sources of heavy metal and trace elements in agricultural and residential areas in Argentina and to evaluate the enrichment of total and HCl-extracted heavy metals. Materials and methods Ninety-four topsoil samples were collected in Córdoba, Argentina (0-10 cm). The majority of the samples were subject to agricultural practices. The possible metal pollution sources were a cement plant and an industrial waste incinerator, a former open-cast uranium mine, petrochemical, and mechanical and metallurgical industries among others. The elements As, and Zn were measured by neutron activation analysis, and Co, Cu, Fe, Mn, Ni, Pb, and Zn were partially extracted by 0.5-M HCl and measured using atomic absorption spectroscopy. Several nonparametric statistics were performed to the dataset in order to accomplish the objectives of the study. Results and discussion The mean total Ba concentration exceeded soil quality guidelines for residential areas, with the maximum total As and Co concentrations surpassing the agricultural and residential limits stated in national and international legislations. The elements As and Ba were found to be controlled by parent factors, whereas Ca, Co, Cr, Cu, Mn, Ni, Pb, and Zn were controlled by both anthropogenic and pedogenic factors. A cement plant was the main source of Ca, Co, Cr, Cu, Mn, Ni, Pb, and Zn, whereas lanthanides, Fe, K, U, and also Zn were associated with a former open-cast operation uranium mine. A correlation analysis showed that soil organic matter and pH had strong associations with 0.5-M HCl-extracted Co, Cu, Mn, Ni, Pb, and Zn. Conclusions Fe-normalized enrichment factors calculated for 0.5-M HCl-extracted heavy metals are potentially significant for characterizing the element bioavailability, the anthropogenic contamination, and the anomaly assessment. According to soil quality guidelines for environmental health, the human and wildlife populations in Córdoba Province might be experiencing toxic As, Ba, Co, Cr, Ta, U, and Zn effects. Therefore, mitigation strategies should be performed on an abandoned mine (Schlagintweit Uranium Mine), Yocsina, Despeñaderos, and Oliva.

“…This assumption was supported by the significant decreases in soil Cu, Zn, Mn, and Pb concentrations with soil depth (Tables 3 and 4) and by the interactions of total and extractable soil Cu concentrations with location type and soil depth in the present study (Table 3 and Figure 3). Soil Zn and Mn concentrations significantly decreased with soil depth in the extractable forms but not in the total forms, suggesting that exchangeable forms of soil metals were more responsive to external inputs than the total forms [37,38]. However, the accumulation of heavy metals in surface soils may also depend on other factors, such as soil binding capacity, solubility of heavy metals, and plant cycling [11,39,40].…”

Remnant forests in urban areas provide vital ecosystem services but are susceptible to many human activities including heavy metal emissions. In this study, we collected 192 samples of mineral soils at depths of 0-3, 3-13 and 13-23 cm in 16 remnant forests (eight natural forests and eight plantation forests) in the urbanized Pearl River Delta, China. We assessed the potential risks of soil Cu, Zn, Pb, Mn, Ni and Cr to the vegetation in these forests based on their total and 0.1 M HCl extractable concentrations. The mean concentrations for all soil samples were 202.7, 102.0, 75.7, 24.3, 30.3, and 7.8 mg/kg for Zn, Mn, Pb, Cu, Cr, and Ni, respectively. Compared to background values, total soil Zn concentrations were higher for both the natural and plantation forests located near both industrial and non-industrial sites; total soil Cu and Pb concentrations were higher near industrial sites, particularly for the natural forests. Total soil Pb, Cu, and Mn concentrations and exchangeable soil Pb and Mn concentrations were higher in the natural forests than in the plantation forests. Total soil Cu and Pb concentrations and extractable soil Cu, Pb, Zn, OPEN ACCESSForests 2014, 5 886 and Mn concentrations decreased with soil depth. Based on these results and previous findings of continued acidification and low phosphorus availability of these soils, we recommend that the growth of these remnant forests can be improved by the application of phosphate rock.

Human activities have caused toxic metal pollution and ecological risks to agricultural soil. In this study, 291 topsoil samples, collected in the agricultural soil system of Yuzhong, China, were selected to study the toxic metals and metalloids contamination characteristics, source and ecological risk based on geostatistics, pollution index, and ecological risk index. The main distribution of As is adjacent to pasture land and mainly comes from animal husbandry; Pb was observed near a coal mining factory and the Yellow River and was derived from industry and transportation; Cd was similar to Pb and was mainly derived from industry, transportation, and agriculture; Cr was found near a cement plant and was derived from industry and transportation; and Hg was found near an urban area and was mainly from industry and domestic garbage. The ratio of these elements exceeding the soil background value reached 99.9%. Except for the excess amounts of Cd and Hg in some samples, Cr, Hg, and As were mostly below permissible limits. Moreover, the comprehensive potential ecological risk of toxic metals is mainly at medium level and below, whereas the risks of Cd and Hg are higher. Control of Cd and Hg is important to prevent soil pollution. This study explains the current contamination situation, the predominant contaminants and their sources, and provides emphasis and direction for agricultural soil remediation.
