A powerful anodic stripping voltammetry (ASV) was proposed using a bismuth film coated on screen-printed carbon electrode (Bi-SPCE) in conjunction with the Tessier’s sequential extraction procedure for determination of various forms of cadmium and lead in soil. A dynamic flow-through stirred extraction system was employed to simulate the natural percolation of liquid through the solid soil that causes

Phytoremediation is an emerging green technology for the management of contaminated soils. Plants that are hyper accumulators are used for in situ removal, degradation or decontamination of pollutant elements. The tolerance of heavy metals is the plant characteristic required for hyper accumulation. Different chelating agents such as Ethylenediamine Tetra-acetic acid (EDTA) facilitate metal uptake

Enhanced subsurface reductive potentials and anaerobic conditions induced by organic residues at oilfield sites may affect arsenic (As) levels in groundwater (GW) and GW-irrigated crops. To substantiate this effect, a Fe/Mn-As binary mineral oxide (FMBO-As) was synthesized by co-precipitation and a series of soil columns packed with varying FMBO-As levels were eluted with simulated oily wastewater

The aim of the present work is to broaden our knowledge on the variability of metals and metalloid concentration levels in surface sediments, macroalgae and mollusc. Accordingly, As, Co, Cr, Cu, Mn, Mo, Ni, Pb, and Zn levels in surface sediments, marine macroalgae species (Ulva intestinalis and Ceramium rubrum) and mollusk (mussel Mytilus galloprovincialis) collected from nine stations along the Sürmene

In view of the constant biological researches, it is important to highlight the necessity to develop new instrumentation techniques. In this way, it is possible to use organisms as biological sensors to define new methodologies for a better understanding of the behavior of living beings. Indiscriminate contamination of soil by herbicide has been receiving more attention due to the increase in agriculture

In this paper, 153 samples of heavy metals in the soil of a coal chemical plant in Northwest China were collected in the study area to predict and evaluate the human health risks of arsenic (As), cadmium (Cd), chromium (Cr(VI)), lead (Pb), and mercury (Hg) in the soil of the plant area in 2021, 2026, and 2031 and their change laws by referring to the “Soil Environmental Capacity Model,” “Technical

Utilizing fine-grained soils containing clay minerals in most of the structures due to the specific surface area, ion exchange capacity and high adsorption capacity of hazardous contaminants have always been considered with the geotechnical view of the environment. In this study, the effect of contamination and stabilization of anionic pollutants (As) on the most important mechanical and physical properties

Cadmium (Cd) is readily absorbed by plants and can accumulate to concentrations that exceed food standards. Testing strategies that can mitigate plant uptake of Cd are essential to help manage the risk to food quality. We measured whether applying silicon (Si) fertilizer to a soil contaminated with Cd from phosphate fertilizer could decrease Cd concentrations in spinach (Spinacia olearacea) and onion

Heavy metal contamination of agricultural soil has become a critical issue worldwide. A sustainable approach to mitigate heavy metal contamination is extremely important. Phytoremediation has been proved to be a well alternative for soil remediation as cost-effective, environment friendly, and esthetically pleasing. This review briefly elucidates heavy metal tolerance, uptake, and the corresponding

The delayed geochemical hazard (DGH) model was used to show that environmental pollution risk from Pb is a dynamic process as opposed to static. The DGH model describes the potential transformation and release of Pb partitioned in the different fractions of the soil that may be inert but becoming reactive when the conditions of the soil such as pH, moisture, and organic matter become favorable or when

High energy consumption is one of the major setbacks of electrokinetic remediation (EKR) of contaminated soils. This study investigated the effect of bentonite/clay ratio, pulse duty cycle and voltage gradient on pulsed electrokinetic remediation (PEKR) of Cu and Pb contaminated soil. Maximum removal efficiencies of 17.81% and 62.41% were achieved for both Pb and Cu, respectively. Adsorption, as well

On April 16, 2016, a series of earthquakes with a maximum magnitude of 7.0 struck Kumamoto Prefecture, Japan, and about 1,300,000 metric tons of land-derived debris (building materials, household appliances, furniture, and wood) required disposal. Because public lands were used as emergency debris storage sites, environmental contamination by organic micropollutants from the debris has been a public

Bioremediation as a low-cost technique can reduce the toxicity of metal ions from the contaminated site including soil and water. In this study, the copper (Cu) and nickel (Ni) bioremediation potential of Microbacterium oxydans strains CM3 and CM7 was investigated under different ranges of environmental factors including pH, temperature, and initial metal concentration by response surface methodology

The knowledge of PAH sources in soil plays an important role in making the decision of pollution emission restriction, as well as toxic information.
