Sodium dodecylbenzene sulfonate (DBS), an anionic surfactant, is used as an important content of detergent. Its discharge without treatment causes environmental problem and its adsorptive behavior in soils is not fully understood. In this study, the adsorption ...

In order to evaluate the heavy metal contamination of soil and plants in Dunhua sewage irrigation area 270 soil samples were collected and examined. This study concludes that irrigation by wastewater has increased the heavy metal concentrations in soil and ...

<p>In this study geochemical fractionation of selected heavy metal in soils from Sukinda mining area was studied using single and sequential extraction technique.</p>

The present study was carried out around Tehran, Iran, where wastewater has been commonly used for irrigation of peri-urban crops for many years. The objective of the present report is to quantify concentration and contamination of Zn, Cu, Ni and Pb in irrigation ...

The purpose of this document is to provide a brief overview of the dynamics of chemical processes that govern contaminant transport and speciation during water exchange across the GW/SW transition zone and to present results from a field study examining the ...

The complex system of interactions between basic environmental components is very often complicated by anthropogenic pollution. Petroleum hydrocarbons and volatile organic compounds represent the most frequent pollutants in the area of the Czech Republic. ...

The distribution of cadmium, lead and zinc in exchangeable, organic, and 2M HNO₃extractable fractions as well as the effect of heavy metal concentrations on soil microflora was investigated.

<p>This series of technical notes examines the urban activities that cause soil degradation, and the management practices that protect the functions urban societies demand from soil. This technical note focuses on heavymetal soil contamination.</p>

Various experimental and theoretical studies have shown that Fick's law, based on the assumption of a linear relation between solute dispersive mass flux and concentration gradient, is not valid when high-concentration gradients are encountered in a porous ...

In part 1 of this thesis, is developed a finite-strain theory for the joint effects of water pumping and surface loads on ground subsidence in a soil system consisting of a hard aquifer sandwiched by two soft and semipervious layers. In the second part of ...
