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.

Total Mercury and Sequentially Extracted Mercury Fractions in Soil Near a Coal-Fired Power Plant

Coal-fired power plants are regarded as major anthropogenic pollution sources of Hg. In order to investigate the content of Hg in soil near a coal-fired power plant, soil samples at different depths and distances from the chimney of the power plant were collected. The concentrations of Hg in samples were determined by cold vapor atomic fluorescence spectrometer (CVAFS).

Alternatives to wheeled loaders: Tracked conveyors and program-controlled conveyor belts have advantages:

Wheeled loaders are still indispensable working machines in many companies – also in construction material recycling plants. They are used because of the long operating hours they are capable of. In addition to the final loading, in many cases intermediate stockpiles are created, although these can result in considerable costs and risks.

Using a polymer and fly ash for developing a non-conventional sorbent

The generation of solid residues is a global problem with severe implications for the environment and industry. On the one hand, high storage, transport and disposal costs of wastes must be faced by industrial producers and on the other hand, toxic substances leaching through the soil to the groundwater may negatively impact terrestrial and aquatic ecosystems due to trace elements contained in solid residues. Nowadays, industry is very interested in the reuse of solid wastes, therefore many investigations are aimed to find new applications for waste use as new raw materials and energy sources.

Hydrodechlorination of PCBs-contaminated soils and groundwaters

As in most South American countries, the magnitude of the Chilean contaminated site problem is yet to be established. To date, only two studies have been conducted for the identification and preliminary risk assessment of sites under suspicion of contamination, considering the associated human health and environmental risks. The latter work is a case study in an industrial Region in South Central Chile, the second most important in social and economic terms.

Field deployment of persulfate-based electrokinetic in-situ remediation

In Austria, 40,438 old industrial sites have been localized (2006), whereas organic pollutants account for 93 % of the contaminated sites and more than 40 % thereof are affected by mineral oil and phenol. Furthermore, there are about 6,000 gas stations in Austria declared as contaminated land (Spausta & Weihs 2006). Up to now, no adequate In-situ remediation method has been developed which can cope with this scale of the problem.
