“…High concentrations of heavy metals in soil in some urban areas have raised concerns over the use of this land for food production (Guo et al 2006;McClintock 2012) and these remnants of industrial history in cities are now becoming a threat to the existence of community gardens and neighborhood vitalization projects (Lewis 1985). There are a large number of studies in literature on the analysis of heavy metal concentrations in contaminated industrial sites or brownfields across the country (Gallagher et al 2008;Jennings et al 2002). Studies have shown that as distance from the city center or major roads increases, accumulation of heavy metals in the surface soil decreases (McClintock 2012;Turer and Maynard 2003;Pouyat and McDonnell 1991).…”

This study assessed the extent of potential human risk to heavy metal exposure by comparing concentrations of arsenic (As), cadmium (Cd), chromium (Cr), lead (Pb) and zinc (Zn) in soil in 43 vacant lots in two low income neighborhoods, Hough (Cleveland, Cuyahoga County, Ohio) and Weinland Park (Columbus, Franklin County, Ohio) in USA to the US Environmental Protection Agency (EPA)'s Soil Screening Levels (SSLs) and to regional background concentrations. At least one soil sample in all the lots in Weinland Park and 27 out of 28 (96%) of the lots in Hough exceeded the natural background concentration of Pb in Franklin (14 to 25 mg/kg soil) and Cuyahoga (56 to 136 mg/kg soil) counties, respectively. When compared to the USEPA's SSL for Pb for human ingestion of soil, soil from only 1 out of 15 (6.6%) lots in Weinland Park and 15 out of 28 (54%) in Hough neighborhood exceeded the SSL of 400 mg Pb/kg soil. All sites in both neighborhoods exceeded the SSL for As (0.4 mg/kg soil); however only 1 lot (6.6%) in Weinland Park and 3 (11%) in Hough exceeded the background concentrations of As in Franklin (9 to 33 mg/kg soil) and Cuyahoga (5 to 20 mg/ kg soil) counties. Thirteen (86%) lots in Weinland Park and 25 (89%) in Hough had soil Zn concentration higher than the background in Franklin County (71 to 177 mg/kg soil) and Cuyahoga County (56 to 137 mg/kg soil) respectively, however they were all within the SSL of 23,000 mg Zn/kg soil. Significant correlations were observed within metals, soil properties, and between metals and soil properties including texture, moisture, pH, organic matter and active carbon suggesting unique associations in the two neighborhoods. Results indicate that Pb is a metal of concern in 54% of the vacant lots in Hough neighborhood. The study Urban Ecosyst highlights the need for comparing vacant lot heavy metal concentrations to both USEPA's SSLs and natural background concentrations in the area for establishing safety of a lot prior to its use for urban agriculture.

“…The positive relationships of Zn between soil non-resistant fractions (EFLE, AR and OO) and plant root indicated a close relationship between soil Zn concentration and root metabolism, which should be further examined to understand how soil Zn concentration can impact root Zn accumulation efficiency. According to [24], when soil metal concentration exceeds the plant tolerance, growth and metabolism will be inhibited and eventually the plant species will be excluded from the site vegetation assemblage even though there is a seed existing in the regional pool. Therefore, the roots, leaves and stems of C. asiatica are good biomonitors of Zn pollution in the environment.…”

The polluted site object of our study was located on an island nourished using different materials, including industrial by-products, inside the area of Porto Marghera (Venice Lagoon, Italy). Until the 1970s, this area was one of the most important chemical districts in Italy and was largely subjected to heavy metals and metalloids pollution. In the year 2004, some Populus and Salix spp. had been planted in this polluted site in order to investigate both the hydrological control and the phytoremediation capability of these trees. In the present work, polluted soil was analyzed at different depths for both metals content and culturable microbial communities with the aim to evaluate the establishment of previously planted poplar and willow plants. Bacteria were characterized on the basis of the r/Kstrategists distribution since r-strategists (fast-growing bacteria) and K-strategists (slow-growing bacteria) are characteristic for unstable and stable environments, respectively. A better characterization of bacterial communities composition was obtained from colony development and eco-physiological indices. Results appeared to confirm a good establishment of poplar and willow plants in the heavy metal contaminated site.
