The objective of the presented work was to conduct an ex-post analysis of land use change in Wroclaw city, Poland, as a response to the soil protection regulations. The assessment that was a part of Urban Soil Management Strategy (URBAN-SMS) project involved development of land use change maps based on the satellite image data, analysis of land use change trends within 15 years period and subse...

Background & Aims of the Study: Heavy metals are the most important contaminants in the soil. Due to their non-biodegradable property, heavy metals can persist in the ecosystem for a long time. Therefore, this research focuses on heavy metal contamination in urban park soils in Asadabad, Hamedan, Iran. Materials & Methods: Altogether 18 composite soil samples were collect...

Introduction: Urban soils are large pools of carbon, nitrogen, and other elements, supporting plant growth, sustaining biogeochemical cycles, and serving as the foundation for maintaining ecosystem function and services of urban green spaces (UGS). Quantifying urban soil properties is essential for assessing urban ecosystem services and detecting pollution. Characterizing spatial heterogeneity ...

In situ inactivation of soil Pb is an alternative to soil removal and replacement that has been demonstrated in recent years at industrial sites with hazardous soil Pb concentrations. Most children exposed to elevated soil Pb, however, reside in urban areas, and no government programs exist to remediate such soils unless an industrial source caused the contamination. Modern regulated biosolids ...

urban expansion and agriculture intensification are relevant drivers in land degradation (ld)processes in europe due to net loss of land, soil sealing, landscape fragmentation and other negative effects on the environment. this paper explores changes (or “trajectories” of change) in land use and cover (lulc) and their relationship with the consumption of soils in emilia-romagna (northern italy)...

Soil contamination is a public health concern in many countries but methods to assess dietary risk from soil metal toxicity have not been standardized worldwide. Laboratory data on urban soils are limited and do not adequately link metal content to associated food plant uptake. Cadmium is a health risk because it accumulates in lettuce and may be consumed at high levels by childbearing women. T...

The investigation of the anthropogenic contamination by heavy metals of soils is very important for environmental planning and monitoring in urban areas. In the present study, surface soils (0 20 cm) samples from 167 sampling sites in Xuzhou (China) were collected in 2010 and analyzed for heavy metals including Zn, Pb, Fe, Mn, Cu, Cd, Sr, Ba Cr, Ni and Mo via inductively coupled plasma/mass spe...

Title of Thesis: THE EFFECTS OF CO2 AND TEMPERATURE ON THE SOIL MICROBIAL CARBON AND NITROGEN OF URBAN AND RURAL FORESTS Elizabeth Kulka, Master of Science, 2015 Thesis Directed By: Professor Marla S. McIntosh Department of Plant Science This study investigated and compared the effects of elevated temperature and elevated CO2 on the microbial biomass carbon (MBC) and nitrogen (MBN) of urban and...

Use of a harmonised sampling regime has allowed comparison of concentrations of copper, chromium, nickel, lead and zinc in six urban parks located in different European cities differing markedly in their climate and industrial history. Wide concentrations ranges were found for copper, lead and zinc at most sites, but for chromium and nickel a wide range was only seen in the Italian park, where ...

Interest in urban agriculture has grown as residents seek to revitalize cities and improve access to fresh produce. Investigators are figuring out how to maximize the benefits of gardening while minimizing the risks of contaminated urban soils.
