Extraction Behavior of Metallic Contaminants and Soil Constituents from Contaminated Soils

Environmental Technology, 2005
With an aim of developing an effective remediation technology for soils contaminated by heavy metals and metalloids, the extraction behavior of metallic contaminants as well as those of soil constituents was studied on a laboratory scale. Three contaminated soils collected from a former metal recycling plant were examined.

Electrorestoration of Metal Contaminated Soils

Environmental Science & Technology, 1994
The removal of metals from contaminated soils using electric fields has been successfully demonstrated in the laboratory, yet field trials have yielded anomalous results. Poor performance may be attributed to interaction of the metals with naturally occurring electrolytes, humic substances, and co-disposed wastes.

Soil Contamination

2015
Soil, the final product of long-lasting forming processes, is a nearly non-renewable source and an environmental necessity. Soil contamination, also known as soil pollution, which is generally defined as the presence of man-made chemicals and alterations in soil, is widely capable of causing long-term health issues and a disrupted ecosystem.

Arsenic speciation in contaminated soils

Talanta, 2002
A method for arsenic speciation in soils is developed, based on extraction with a mixture of 1 mol l(-1) of phosphoric acid and 0.1 mol l(-1) of ascorbic acid, and further measurement with the coupling liquid chromatography (LC)-ultraviolet (UV) irradiation-hydride generation (HG)-inductively coupled plasma mass spectrometry (ICP/MS).

Bioremediating herbicide-contaminated soils

Applied Biochemistry and Biotechnology, 1993
Combinations of landfarming and biostimulation were evaluated for remediating pesticide wastes. Various amounts of soil contaminated with alachlor and trifluralin (> or = 100 mg/kg each) and metolachlor and atrazine (> or = 20 mg/kg each) were applied to field plots, and sewage sludge or corn meal was incorporated into designated plots. Plots were also

Bioremediation of soils contaminated with explosives

Journal of Environmental Management, 2004
The large-scale industrial production and processing of munitions such as 2,4,6-trinitrotoluene (TNT) over the past 100 years led to the disposal of wastes containing explosives and nitrated organic by-products into the environment. In the US, the Army alone has estimated that over 1.2 million tons of soil have been contaminated with explosives, and ...

LANDFARMING IN A PAH-CONTAMINATED SOIL

Journal of Environmental Science and Health, Part A, 2001
The present work describes a coke oven soil treatability study by land-farming, conducted on-site in a field scale facility covering 100 m2. The soil contamination was mainly due to high concentrations of polynuclear aromatic hydrocarbons (PAHs) up to 1,140 mg/Kg dry weight (sigma EPA).

Solubility of Cyanide in Contaminated Soils

Journal of Environmental Quality, 1994
AbstractAt more than 200 sites in the Netherlands, the soil is contaminated with cyanide as a result of industrial activities. The mobility of cyanide, which mainly occurs in the form of iron cyanide complexes [Fe(CN)63− + Fe(CN)64−], plays an important role in predicting the possible hazards for the environment and human health.

Phytostabilization of Metal Contaminated Soils

Reviews on Environmental Health, 2010
The contamination of soils with heavy metals represents a worldwide environmental problem of great concern. Traditional methods for the remediation of metal contaminated soils are usually very expensive and frequently induce adverse effects on soil properties and biological activity.

Behaviour of Inorganic Contaminants in Soil

1986
From general surveys of soil science literature a number of concepts of soil become apparent which may be quite different, although they all pertain to the same subject. It usually depends on the viewpoint of the author, mainly determined by his personal scientific interest or background, what is the predominant nature of the concept he uses, e.g ...
