“…This suggests that the natural concentrations of Hg, Pb, Zn, and Cu in a few samples were significantly elevated by human activities. The metal concentrations observed were comparable to those reported for suburban soils in Beijing (HU et al 2006) but lower than those observed in the industry-based suburban area of Wuxi (Zhao et al 2007). Compared with two water source protection zones, in Beijing and the Pearl River delta, the Shanghai water source protection zone had significantly higher concentrations in soil of all heavy metals except As (Table 2).…”

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.

“…1, bottom). The variation in elevation was 5-8 m. Situated in a north subtropical monsoon climate with concentrated rainfall during the period between May and September, annual mean temperature is in the range 15-17°C and annual mean rainfall is in the range 1,000-1,400 mm in the study area (Huang et al 2006;Zhao et al 2007). The soil comprises of stagnic Anthrosols (Chinese taxonomy) (Gong et al 2003, which uses US taxonomy) to Inceptisols , developed on lacustrine deposits.…”

“…Air pollution and particulate matter offer another source of potential pollutant input to urban or peri-urban farming. Zhao et al (2007) studied the spatial distribution of heavy metals in agricultural soils of peri-urban areas of Wuxi, China, and found elevated levels of As, Hg, Cu, Cd, Cr, Zn, and Pb. They associated these elevated levels with nearby metallurgy, electroplating, and steel-making industries. Similarly, Hu et al (2006) studied soils on the outskirts of Beijing, China, and found elevated levels of similar metals.…”

Urban expansion into traditional agricultural lands has augmented the potential for heavy metal contamination of soils. This study examined the utility of field portable X-ray fluorescence (PXRF) spectrometry for evaluating the environmental quality of sugarcane fields near two industrial complexes in Louisiana, USA. Results indicated that PXRF provided quality results of heavy metal levels comparable to traditional laboratory analysis. When coupled with global positioning system technology, the use of PXRF allows for on-site interpolation of heavy metal levels in a matter of minutes. Field portable XRF was shown to be an effective tool for rapid assessment of heavy metals in soils of peri-urban agricultural areas.
