Redevelopment of brownfields sites is a challenging issue throughout the world, which has gained increasing attention in recent years. Lands affected by oil wastes and products are among common types of brownfields sites in Iran. Sorghum (Sorghum bicolor) was employed to remediate diesel polluted soils in this study. The main aims of this study were to examine the phytoremediation potential of ...

BACKGROUND Several species belonging to the ecological group of white-rot basidiomycetes are able to bring about the remediation of matrices contaminated by a large variety of anthropic organic pollutants. Among them, polychlorobiphenyls (PCBs) are characterized by a high recalcitrance due to both their low bioavailability and the inability of natural microbial communities to degrade them at si...

The aim of the research was to compare the effects of various petroleum products, biodiesel, diesel oil, fuel oil and unleaded petrol on soil dehydrogenases, and to evaluate biostimulation with compost and urea in the restoration of homeostasis of the soil contaminated with these products. The obtained results allowed for defining the weight of dehydrogenases in monitoring of the environment su...

An available remediation technique--arbuscular mycorrhizal phytoremediation (AMPR)--is further proposed for soils contaminated with phenanthrene and pyrene as representative polycyclic aromatic hydrocarbons (PAHs) utilizing a greenhouse pot experiment. The initial concentrations of phenanthrene and/or pyrene in soils were 103 mg kg(-1) and 74 mg kg(-1), respectively. The host plant was alfalfa ...

Soil properties are important factors modifying metal bioavailability to ecological receptors. Twenty-one soils with a wide range of soil properties (USA; http://soils.usda.gov/technical/classification/taxonomy/) were amended with a single concentration of Pb (2,000 mg/kg) to determine the effects of soil properties on Pb bioavailability and toxicity to earthworms. Earthworm mortality ranged fr...

Phenolic contaminants can become irreversibly bound to organic matrices in soils and sediments. The bound chemicals have been shown to possess attenuated environmental mobilities and reduced bioavailabilities. The purpose of this ongoing study is to a) evaluate the factors affecting binding of phenols to natural soils, sediments and aquifer material, and b) utilize this information to develop i...

The influence of direct current electric fields on the possible electrokinetic delivery of nano-iron slurry in clay for the purpose of fast and effective remediation of soil contaminants has been tested. Nano-iron can be introduced to soil hydraulically in slurry form, but in tight clay soil, delivery of a uniform distribution of the slurry may be difficult to achieve for effective remediation....

• Vitrification is an effective method for soils remediation. Soils can be suitable making glass. Usually some additions are necessary. Potentially toxic elements from retained in the glass structure. The use of contaminated as raw material has economic benefits. Contaminated area previously occupied by a metal smelting industry Barcelona city were used was investigated possible remediation tec...

Many organic chemicals have known human and environmental health hazards. At sites where chemicals have historically been stored, mixed and transferred, spills have often occurred. A primary route for human exposure to hazardous chemicals is by drinking groundwater which has been contaminated due to spills onto soil (Wilson et al., 1986) Due to the potential human health risks associated with e...
