Solidification and Stabilization of Contaminated Soil
… huge promise in dealing with the clean up of soils contaminated with pollutants listed as Hazardous Substances under Resource Conservation and Recovery Act (RCRA). The site discussed in this paper was contaminated with Naphthalene, heavy metals and other VOCs. In order to find an effective …

Bioremediation of petroleum hydrocarbon contaminated soil
The bioremediation of petroleum contaminated soil in large-scale treatment units was studied in conjunction with Sybron Chemicals Inc., Salem, VA. The soil had been previously contaminated and was spiked with additional petroleum. Water with different characteristics was circulated through the soil …

Enhanced petroleum-contaminated soil bioremediation by plants
A petroleum-contaminated soil remediation study was conducted in a greenhouse. The system consisted of 36 pots, 12 were vegetated with squash, 12 were vegetated with fescue grass and the last 12 units served as unvegetated controls. For each group, three treatments were applied, 1) the addition of …

Characterization of TPH biodegradation patterns in weathered contaminated soil
Two weathered, petroleum contaminated soils were studied to determine if weathered products are amenable to bioremediation and to determine which TPH (total petroleum hydrocarbon) fractions were degrading during particular time frames under different remediation alternatives. Delineation of …

Bioremediation of biodiesel and diesel contaminated soil by pseudomonas putida
… containing polyaromatic hydrocarbons (PAHs) in soil is toxic to humans, plants and soil microorganisms due to their recalcitrant and mutagenic or carcinogenic properties. Therefore, this study was conducted to suggest a new technique of treatment to clean up the biodiesel and diesel contaminated …

Microcosms and field bioremediation studies of Perchloroethene (PCE) contaminated soil and groundwater
… Biostimulation of the natural ground water and soil microflora did not completely degrade PCE as cis-DCE (c-DCE) accumulated in the sample. Bioaugmented microcosms containing YE and SOME created reducing conditions for KB-1 culture, resulting in ~ 90% dechlorination of PCE to methane and c-DCE. …

The study of rehabilation of hydrocarbon contaminated soil using bio-remedial microbes
… option for chronically diesel-oH-poHuted soil at petroleum and gas depot of Oilco (a company that is a division of Shell) situated at the east side of Empangeni which is in the Northern KwaZulu-Natal province, South Africa. To examine the efficiency of bioaugmentation, the contaminated …

Stabilization/solidification of lead contaminated soil using cement incorporated with sugarcane bagasse
Soil that is contaminated with heavy metals, especially lead (Pb) has become a major issue worldwide. Pb is reported to be a metal that affects human health and is related to have caused serious diseases that interrupts the nervous system, blood vessels and kidneys. However, proper treatment …

Remote sensing of grassland with contaminated soil using the spectral red-edge
In most cases contaminants are concealed in soil and under vegetation and therefore can<br/>not be measured directly by remote sensing. However, soil contaminants were detected<br/>using the spectral red-edge to indicate vegetation stress caused by the presence of<br/>the contaminants. An improved …

Stabilisation and solidification of contaminated soil using cement and sugarcane bagasse ash (SCBA)
Soil that is contaminated with heavy metals has become a major issue worldwide. However, proper remediation techniques such as stabilisation/solidification (S/S) method can be employed and is capable of controlling these heavy metals. Conventionally, the common S/S method used cement as binder on …

Chemically Induced Phytoextraction of Lead (Pb) Contaminated Soil by Switchgrass (Panicum virgatum L.)
<p>Soils contaminated with lead (Pb) from human activities including industrial byproducts create an environmental and human health risk. Phytoextraction through chemical acquisition of Pb in soils offer a potentially cost effective and ecologically driven approach to remediation. Switchgrass …

A new method for the routine trace analysis of polychlorinated biphenyls in waste oil and contaminated soil
… than 50 mg/l. PCB analysis in oils and oil contaminated soil is normally expensive in terms of time, instrumentation and uses large volumes of hazardous solvents which further increase cost per sample. Commercial laboratories are constantly under pressure to provide a faster turnaround time …

The association between acute childhood diarrhoea and diarrhoeagenic E.coli present in contaminated soil in informal settlements in Durban
Submitted in fulfillment of the requirements of the degree of Master of Health Sciences in Environmental Health, Durban University of Technology, Durban, South Africa, 2016.

Purification of human dna for dna profiling from body fluid contaminated soil using superparamagnetic iron oxide nanoparticles (spions).
Extraction of good quality DNA from soil samples is difficult due to the co-extraction of humic acid and phenolic compounds which can inhibit downstream DNA profiling of samples. Several methods are available for DNA extraction from soil including a number of commercially available kits. We used …
