Effect of warfare waste on soil: a case study of Gallipoli Peninsula (Turkey)
Gallipoli is a small town on the European side of the Dardanelles Strait, in Turkey. More than 450,000 soldiers gave their lives on the Gallipoli Peninsula (Gallipoli Campaign) over a nine-month period during World War I. In that war, many naval and landing bombs were exploded. The ingredients of these bombs may cause heavy metal contamination in soils. An environmental geochemical investigation ...

Geochemical studies to delineate topsoil contamination around an ash pond of a coal-based thermal power plant in India
In the present study, an attempt was made to delineate soil contamination around the ash pond of a coal-based thermal power plant. The topsoil in the study area was found to be contaminated to varying degrees from ash disposal. The soil drawn from various profiles was largely contaminated by ash fall out, predominantly in the prevalent wind direction. Pb, Zn, Cu, Ni, Co, Mn, Cr, V and Ba were ...

Stability and environmental geochemical profile of toxic heavy metals in soils around a crude oil refinery
Soil samples were taken near oil refinery activities, bulk and fractionated heavy metal contents, as well as other physico-chemical characteristics were measured. The reported results indicate that the enrichment factors of the measured heavy metals were 3.9, 1.8, 1.3, 23.7 and 52.5 for lead, nickel, zinc, cadmium and mercury, respectively. The samples can be considered to be extremely ...

Environmental assessment of depleted uranium used in military armor‐piercing rounds in terrestrial systems
Depleted uranium (DU) from the military testing and use of armor‐piercing kinetic energy penetrators has been shown to accumulate in soils; however, little is known about the toxicity of DU geochemical species created through corrosion/weathering. The purpose of the current study was to assess the toxic effects and bioaccumulation potential of field‐collected DU oxides to the model terrestrial ...

Fate and spatial variations of polybrominated diphenyl ethers in the deposition within a heavily urbanized area: case of Paris (France)
In this paper, we present the first results on the geochemical cycle of PolyBrominated Diphenyl Ethers (or PBDE) in the Paris Region (France). In order to provide information about the distribution and mobility of eight PBDE congeners, we first determined the level of contamination of different environmental compartments: i.e. atmosphere, soils and waters. Atmospheric PBDE deposition was ...

The impact of an open waste disposal site on soil and groundwater pollution
A study has been carried out of a waste disposal site, located in the valley of a small creek, 3 km south of Canakkale city centre. The surface area of the site was around 101000 square metres, and the total amount of waste deposited at the site since 1990 was approximately 1001000 tons. The major risks of the dump are its closeness to the university campus area to the south, the airport to the ...

Natural Attenuation in Soils
Introduction Surface and subsurface soils have different characteristics in natural attenuation. Mobile contaminants in subsurface soils diffuse into soil vapor and aqueous phase and thus are relatively easily subject to natural subsurface processes that can attenuate these contaminants. Most high-molecular-weight (persistent) organic and many inorganic contaminants will be immobilized in the ...

Bioaugmentation is a cost-effective and sustainable remediation alternative
Selecting a remediation alternative that is compatible with the natural soil and ground water conditions is not only a more sustainable approach, but leads to significant savings. Comparison between bioaugmentation and other remediation methods in the five recognized sustainability criteria demonstrates the advantages of bioaugmentation. While this paper is nota complete quantitative analysis, it ...

Metals Stabilization Using Geochemical Fixation
Introduction To Chemical Fixation There are several approaches to treatment of chromium and other toxic metals such as lead arsenic, and cadmium in soil and groundwater, including isolation, immobilization, toxicity reduction, physical separation, and extraction (U.S. EPA. 2002). Brief Overview Of Metals Remediation Methods: Conventional Methods: Conventional approaches to ex-situ remediation ...

DNA-Stable Isotope Probing Technology (DNA-SIP)
Background DNA-stable isotope probing technology (DNA-SIP) is a molecular ecology technology that uses stable isotopes to trace the genomic DNA of microorganisms in complex environments. Making use of stable isotopes to trace microbial genomic DNA in complicated environments can realize the transformation of research from single microbial physiological process to physiology and ecology of ...
