Soil reagent mixing (SRM) is a remediation technique whereby powder or slurried reagents are delivered and mixed in-situ or ex-situ with contaminated soils or sediments by augers or other types of soil mixers. This paper summarises the work carried out for a laboratory treatability study of SRM on clayey soil samples contaminated with petroleum hydrocarbon compounds from a petrol filling statio...

Oil spills and petroleum based pollutions are very common which cause a potential threat to both terrestrial as well as aquatic life. Bioremediation has become an alternative way to remedy. These microorganisms can degrade a wide range of target constituents present in oil sludge. An ability to isolate high numbers of certain oil degrading microorganisms from an environment is commonly taken as...

Dissipation of petroleum contaminants in the rhizosphere is likely the result of enhanced microbial degradation. Plant roots may encourage rhizosphere microbial activity through exudation of nutrients and by providing channels for increased water flow and gas diffusion. Phytoremediation of crude oil in soil was examined in this study using carefully selected plant species monitored over specifi...

Members of the Sphingomonas genus are often isolated from petroleum-contaminated soils due to their unique abilities to degrade polycyclic aromatic hydrocarbons (PAHs), which are important for in situ bioremediation. In this study, a combined phenotypic and genotypic approach using streptomycin-containing medium and Sphingomonas-specific PCR was developed to isolate and identify culturable Sphi...

introduction growing use of hydrocarbon constituents in various industries have generated significant quantities of hazardous wastes which lead to environmental pollution. in recent years, the strong global demands for fossil fuels and industrial chemicals have resulted in the release of some of these compounds into soil, water and air.hydrocarbon-contaminated soils are among the important envi...

Natural attenuation of petroleum hydrocarbons in polar and subpolar soils is limited by low nutrients, low temperatures, and water availability. This study investigated three sites contaminated with diesel fuel and the use of aeration to remediate one of the sites at sub-Antarctic Macquarie Island. These sites were of differing ages and had different soil–water regimes. The most recent spill (N...

Plant-based remediation is a relatively new, efficient, and environmentally friendly technology, which can be promising for removing many contaminants like hydrocarbon pollutants. The main objectives of the current study were to investigate the effect of petroleum hydrocarbons with high initial concentration (about 3.5% by weight) on growth characteristics of maize (Zea mays L.), and tall fescu...

– Local content policy in Nigeria promotes the development of innovative indigenous technology aimed at contributing to national science and technological development. Consequently, bioremediation agent (Ecorem) was formulated from Nigeria local raw materials as a contribution to enhanced environmental performance in the petroleum sector. As part of evaluating kinetic mechanism of this product,...

phytoremediation has gained increasing attention in recent years because of its ability to clean up and redevelop brownfield sites. petroleum hydrocarbon-contaminated sites are among most prevalent industrial sites in iran as one of the top oil producers in the world, which are in great need of remediation to prevent associated environmental and human health risks. a greenhouse study was conduc...
