Characterized by expensive housing, high socioeconomic status, and topographic relief, Upper Sonoran Lifestyle communities are found primarily along the Wildland-Urban Interface (WUI) in the Phoenix, Arizona metro area. Communities like these sprawl into the wildlands in the United States Southwest, creating a distinct urban fringe. This article, through locational comparison, introduces and ev...

The aim of this study was to analyze changes in the content of selected polycyclic aromatic hydrocarbons (PAHs) in urban soils fertilized with municipal sewage sludge. The factors in the experiment were three lawns along the main roads in Bialystok (in Popieluszki, Hetmanska and Raginisa Strs.), doses of sewage sludge (0 – control; 75 and 150 Mg/ha) and two years of study (2011 and 2012). The s...

Soil Fungi May Help in Lead Remediation Lead contaminates soil in many urban areas. Investigators have discovered that lead can be transformed by multiple soil fungi into a stable form known as chloropyromorphite, suggesting a potential new tool for cleaning up soil lead contamination. This ability of the fungi may help them to survive in contaminated locations. The authors write that “fungal m...

The largest natural biological sink for the radiatively active trace gas methane (CH4) is bacteria in soils that consume CH4 as an energy and carbon source. This sink has been shown to be sensitive to nitrogen (N) inputs and alterations of soil physical conditions. Given this sensitivity, conversion of native ecosystems to urban, suburban, and exurban managed lawns thus has potential to affect ...

[1] We measured soil nitrogen (N) cycling and fluxes of N2O and NO in three land-use types across the metropolitan area of Phoenix, Arizona. Urbanization increased N2O emissions compared to native landscapes, primarily due to the expansion of fertilized and irrigated lawns. Fluxes of N2O from lawns ranged from 18 to 80 mg N m!2 h!1 and were significantly larger than managed xeric landscapes (2....

Under rapid urban sprawl in Northeast China, land conversions are not only encroaching on the quantity of cultivated lands, but also posing a great threat to black soil conservation and food security. This study's aim is to explore the spatial relationship between comprehensive cultivated soil heavy metal pollution and peri-urban land use patterns in the black soil region. We applied spatial la...

Background and purpose: In the process of rapid urbanization and industrialization in developing countries, environmental pollution is a major concern. One of the fastest growing problems of environmental pollution is an excessive intake of lead in urban soils. Lead concentrations in urban soil may result from human activities such as vehicle emissions and industrial activit...

this study investigates the status of heavy metals contaminations in urban soils of ostrava inthe czech republic. the main aim of this study was determination of concentration of cd, pb, zn, cu, mn,v and hg, assessment of contamination levels of metals in urban soils and verification of potential source ofmetals contamination. soil samples were collected from soil layer of 20 cm and metals were...

mercury is a dangerous and an extremely toxic element, which can transfer to the food chain.presence of this element in the atmosphere particularly during the rainy seasons cause soil and environmental pollution, therefore this research will evaluate the transformation of mercury vapor from the atmosphere through precipitation into the soil. in the present study, mercury concentrations were det...
