This study was aimed to investigate the electrokinetic removal of environmental hormone––nonylphenol (NP)––from soil matrix under potential gradient of 1 V cm−1 for 5-day treatment. The EK experiments were conducted with four processing fluids of de-ionized water, citric acid, NaOH, and methanol in a Pyrex glass cylindrical cell. Results showed tha...

In this study, a circulation-enhanced electrokinetics (CEEK) system integrated with the stepwise addition of chemical reagents was used to remediate copper-contaminated soils collected from a real site. At first, an optimal extraction process of different chemical reagents was found to obtain the highest copper removal efficiency by conducting batc...

Worldwide there are numerous regions where conventional agriculture is affected by the presence of elevated amounts of plant-available trace elements, causing economic losses and food and feed quality and safety. The Belgian and Dutch Campine regions are a first-class example, with approximately 700 km(2) diffusely contaminated by historic atmosphe...

Background, aim, and scopeSoil remediation with ethylenediamine tetraacetic acid (EDTA) leaching is capable of removing only part of the total metal concentration in the soil, mostly the labile, bioavailable metal species (metal bioavailability stripping). However, reintroduction of remediated soil in the environment exposes the soil to various env...

The present study investigated the feasibility of using two mixed surfactants, anionic surfactant sodium dodecylbenzenesulfonate (SDBS) and nonionic surfactant polysorbate 80 (Tween80), for the remediation of p-nitrochlorobenzene (pNCB) contaminated soil. The water solubility, the apparent soil-water distribution constant (K(d)(*)) and the desorpti...

A three-level full factorial design has been conducted to assess the influence of gas flow-rate, ozone concentration and reaction time on the remediation of soil contaminated with four PAHs (namely acenaphthene, phenanthrene, anthracene and fluoranthene). Under the operating conditions investigated, reaction time and ozone concentration seem to exe...

Potassium permanganate, widely used in water treatment, has shown its applicability to reduce PAH contamination in groundwater and soils. The first stage to design a treatment at the site scale is the feasibility study at the bench scale, generally performed by means of batch experiments. The aim of the present contribution was to investigate the i...

Large areas of land contaminated with cadmium (Cd), lead (Pb), and zinc (Zn) are currently in agricultural production in the Campine region in Belgium. Cadmium contents in food and fodder crops frequently exceed legal threshold values, resulting in crop confiscation. This imposes a burden on agriculture and regional policy and, therefore, encourage...

Cupriavidus metallidurans CH34 and related strains are adapted to metal contaminated environments. A strong resistance to environmental stressors and adaptation make it ideal strains for survival in decreasing biodiversity conditions and for bioaugmentation purposes in environmental applications. The soil bacterium C. metallidurans is able to grow ...
