Influence of Mycorrhizal Fungi on Remediation of Soil Contaminated by Petroleum Hydrocarbons
© PSP - Parlar Scientific Publications (12/2010)
Arbuscular mycorrhizal fungi (AMF) can play an important role in phytoremediation by improving plant establishment and growth on soils contaminated by anorganics as well as organics. The benefits of AMF to plants are often related to increased nutrition and water uptake as well as enhanced tolerance to environmental stress. The aim of the present study was to investigate the efficacy of remediation techniques (plant cultivation, bacterial inoculation, arbuscular mycorrhizal fungi inoculation) on petroleum contaminated soil.
Geotechnical characterization of waste

Near Maastricht, The Netherlands, urban development on a waste disposal site is planned. Since building on a waste disposal site is relatively new geotechnical based risk management approach has been adopted for the feasibility study of the urban development. It was found that settlement of the landfill and stability of the slope imposes the largest risks to the project. Camera probe measurements and large-scale laboratory tests were conducted to optimize the design.
Two-step biological treatment of coke oven wastewater

Due to high concentrations of pollutants, some of them inhibitory or toxic, coke oven effluents belong to the most delicate industrial wastewaters. Application of conventional biological treatment technology requires low-loaded, i. e. large volume bioreactors.
New Objectives of Sludge Treatment Considering a Safe Sludge Removal

Sewage Sludge consists of valuable compounds such as nutrients as well as harmful substances e.g. heavy metals. For sludges with a low pollutant concentration, utilization in agriculture is the best option for sludge reuse.
