Assessment of trace and heavy metal distribution by four sequential extraction procedures in a contaminated soil
fractionation metals mining activities pollution
2015/3/9
Four sequential extraction procedures (Sposito, Tessier, Silveira and Bureau Communautaire de Reference (BCR)) were used to evaluate the distribution of some metals (Fe, Cu, Cd and Zn) in a contaminat...
Effect of temperature on the distribution of polycyclic aromatic hydrocarbons in soil and sediment
sorption desorption thermodynamic parameters polycyclic aromatic hydrocarbons
2015/2/4
The knowledge of sorption-desorption processes of polycyclic aromatic hydrocarbons (PAHs) in natural solids is essential to predict the fate, transport, and environmental risks of these pollutants. In...
Soil texture fractions and fractal dimension of particle size distribution as predictors of interrill erodibility
Erosion predictor fractal dimension interrill erodibility soil texture
2011/3/22
Choosing a particular textural fraction as an erodibility predictor is often confusing because various fractions of soil particles have been introduced as erodibility index by many researchers. Recent...
The available soil water capacity (ASWC) is important for studying crop production, agro-ecological zoning, irrigation planning, and land cover changes. Laboratory determined data of ASWC ...
Based on Universal Soil Loss Equation and methods of mathematics model and GIS analysis, this study classified influence of precipitation, soil, topography and vegetation upon sensitivity ...
The copper (Cu) content in 205 soil samples (0-20 cm) of Tibet, covering 5 soil classes, were analyzed. The results showed as follows: (1) the average content of Cu was 19.6 mg kg-1 (CV=49...
