Chromium In Urban Soil-Plant-Water Ecosystems

Arsenic and chromium speciation in an urban contaminated soil.

The distribution and speciation of As and Cr in a contaminated soil were studied by synchrotron-based X-ray microfluorescence (μ-XRF), microfocused X-ray absorption spectroscopy (μ-XAS), and bulk extended X-ray absorption fine structure spectroscopy (EXAFS). The soil was taken from a park in Wilmington, DE, which had been an important center for the leather tanning industry along the Atlantic s...

Running Head: Soil and Vegetation C in Urban Ecosystems

Soil Nutrient Assessment for Urban Ecosystems in Hubei, China

Recent urban landscape vegetation surveys conducted in many cities in China identified numerous plant nutrient deficiencies, especially in newly developed cities. Soil nutrients and soil nutrient management in the cities of Hubei province have not received adequate attention to date. The aims of this study were to characterize the available nutrients of urban soils from nine cities in Hubei pro...

Soil-moisture limits on plant uptake: An upscaled relationship for water-limited ecosystems

Transpiration in water-limited ecosystems is controlled by the availability of soil moisture. Rain events in these natural environments may only partially wet the root zone, leading to a heterogeneous distribution of available water. This spatial variability coupled with the non-linearity of the function relating local uptake to local saturation produces a non-unique relationship when these qua...

Relationships between Soil Properties and Plant Species Diversity in Natural and Disturbed Ecosystems (Case Study: Jamilabad Region, Kerman Province, Iran)

Reduction of species diversity which is a significant threat to the earth has been found more important and has attracted attention among ecologists over recent years. This research was carried out to determine the relationships between plant species diversity indices and soil properties by multivariate regression methods in Jamilabad region, Baft, Kerman province, Iran in 2016. Different sites...
