Soil Washing for Remediation of Non Volatile Hydrocarbon Polluted Soils
This paper illustrates the possibilities of applying what is essentially a physical soil-washing technique for treatment of soil contaminated by semi-volatile hydrocarbons in order to reduce the level of pollution to that permitted by Italian regulations. The ground around a factory producing lubricating-oil additives consists of silty-sandy soils, which have long been contaminated by heavy hyd...
متن کاملChemical Fractionation of Cadmium, Copper, Nickel, and Zinc in Contaminated Soils
Heavy metals are potentially toxic to human life and the environment. Metal toxicity depends on chemical associations in soils. For this reason, determining the chemical form of a metal in soils is important to evaluate its mobility and hioavailability . Sequential extraction was used to fractionate four heavy metals (Cd, Cu, Ni, and Zn) from nine contaminated soils into six operationally defin...
متن کاملEnhanced electrokinetic remediation of cadmium contaminated soils by chelating agents
Electrokinetic soil remediation by electroosmosis and ionic migration is restricted to soluble substances. At a higher pH, the soil particles sorb more heavy metals than at a lower pH and the precipitation reactions of heavy metals are promoted. Both mechanisms make heavy metals immobile, rendering cleanup more difficult and electrokinetic extraction inefficient. In this study, the effectivenes...
متن کاملAnalysis of the Effective Factors on the Electro Remediation of Polluted Soils, an Action Towards Green Technology and Sustainable Environmental Improvement
Today, the issue of sustainable development has become one of the most important global issues and has become the focus of attention and human attention in the economic, social, and environmental perspectives. Various human activities, as well as the development of industries and the expansion of urbanization with waste and wastewater, have contaminated soil. Different methods are available to ...
متن کاملAccumulation of Lead, Cadmium, Nickel, Iron, Copper, and Zinc in Bones of Small Mammals from Polluted Areas in Slovakia
The accumulation of lead (Pb), cadmium (Cd), nickel (Ni), iron (Fe), copper (Cu), and zinc (Zn) in the femora of four rodent species (Apodemus flavicollis, Apodemus sylvaticus, Myodes glareolus, and Microtus arvalis) trapped at different polluted areas in Slovakia (Kolíňany and Nováky) was investigated in the present study. We detected the highest concentration of Pb in bones of A. sylvaticus f...
