Vegetable oil extraction of petroleum hydrocarbons from soil and subsequent separation via non-woven fabrics
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
The current combination, though, of using microemulsions of plant oil in water to extract mineral hydrocarbons in-situ from the soil and to separate that contaminated oil phase from water via non-wovens is novel and in preliminary experiments was shown be to very promising in terms of costs and performance.

Degradation of similar Iprodione pesticides and their dichloroanilines (DCAs) metabolites by pesticide-degrading rhizobacteria
© European Compost Network ECN e.V. (6/2014)
Important worldwide efforts to investigate bioremediation strategies have been encouraged to reduce environmental impact caused by pesticide application in the last years. In this way, the rhizodegradation in cooperation with pesticide-degrading rhizobacteria might be a suitable alternative to avoid point source contamination by pesticides and their metabolites. Therefore, the objective for this study was to test the degradation of similar iprodione pesticides and their dichloroaniline (DCA) metabolites by pesticide-degrading rhizobacteria.

Heat energy exchange of reed canopy over Goheung bay

Heat energy exchange is very important processes in the coastal wetland ecosystems. We observed and analyzed the net radiation flux, the sensible heat flux, the latent heat flux and the soil heat flux, which are balanced in the heat energy balance, over a reclaimed land covered with reeds at Goheung, where is horizontally plane. The atmospheric turbulence had been measured in order to estimate the heat transfer during 5 intensive observation periods (IOPs).

Arsenic contaminated environments: bioremediation perspective from molecular analysis on the bacterial arsenical metabolism
© Aristotle University of Thessaloniki (6/2009)
The metalloid arsenic (As) can be released from geological formations and it is widely used in anthropogenic activities (industry, agriculture, etc.) contaminating several aquatic and soil environments. The arsenate As(V) and arsenite As(III) can be subject to microbiologically oxidation, reduction and methylation reactions. Indeed, bacterial metabolisim of arsenical species in the environment is critical in the As cycle. In the present study, novel aerobic bacterial strains responsible for the oxidation and reduction of As were isolated in water samples supplemented with arsenite or arsenate.

A greenhouse experiment was carried out using three groups of 12 pots each, filled with surface soil spiked by single and binary cadmium and nickel aqueous solutions. Measured bioavailable metal concentrations in soil ranged widely and were up to 246.7 mg kg-1 for Cd and 61.1 mg kg-1 for Ni.

A combined landfarming-phytoremediation system for remediation of petroleum hydrocarbons and metals from contaminated soils
© Aristotle University of Thessaloniki (6/2009)
Petroleum hydrocarbons are among the most common groups of persistent organic contaminants in the environment and are known to be toxic to many organisms. In this study, plant establishment and growth in two petroleum contaminated soils (S1 and S2), which were previously treated using landfarming technique, was evaluated. Investigation of phytoremediation technique for remediation of heavy metals in these petroleum contaminated soils was also part of the purpose.

Bioremediation of petroleum-contaminated soil using landfarming technique: Influence on soil biological and chemical properties
© Aristotle University of Thessaloniki (6/2009)
Petroleum hydrocarbons are a carcinogenic group of contaminants which are widely distributed in the environment. In this study, bioremediation of two petroleum-contaminated soils around the Tehran Oil Refinery (S1 and S2) using landfarming technique was evaluated. The effect of this technique on some biological and chemical properties of investigated soils at the end of each month of the experimental period (4months) was also part of the goal.

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.

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.

Many industries utilize water for processing and for the movement and storage of by-products and waste. This results in large volumes of liquid or slurry-like materials being stored in impoundments, or being treated before discharge into lakes, rivers and streams. In the past, many industry by-products were discharged directly into water courses where they have settled, and over time, have contaminated the sediments of these water courses.
