In this research a pot experiment was carried out to investigate the remediation ability of E. camaldulensis Dehnh inLead-Zinc (Pb-Zn) contaminated soil. The study also investigated the effects of ethylenediaminetetraacetic acid(EDTA) and diethylenetrinitrilopentaacetic acid (DTPA) on the phytoremediation efficiency of the plant species, andharvest time as a suitable dose of chelating agents wa...

The utilisation of industrial bi-products such as cement kiln dust (CKD) is of increasing importance as an option for stabilising contaminated sites due to its pozzolanic nature and also in view of minimising the environmental impact. The experimental programme was carried out in the present study to evaluate the efficacy of CKD as stabilising agent at different percentages 2%, 6%, and 14% (w/w...

The eco-toxicological indicators used to evaluate soil quality complement the physico-chemical criteria employed in contaminated site remediation, but their cost, time, sophisticated analytical methods and in-situ inapplicability pose a major challenge to rapidly detect and map the extent of soil contamination. This paper describes a sensor-based approach for measuring potential (substrate-indu...

The dangers to the handler of syringes used for routine injections were found to be negligible, but known infected syringes and those contaminated with antibiotics should be autoclaved before handling as a high proportion of these carry pathogenic organisms. Mechanical methods of cleaning syringes and instruments are assessed. The use of an artificial soil for testing purposes is described. Usi...

A new technology has been developed for the treatment of contaminated water and soils with lignin derivatives. It has been demonstrated that this technology can be used in the process of removal of high levels of mercury from water, and in the immobilization of leachable mercury in contaminated soils. Lignin derivatives contain an abundance of oxygen-containing functional groups such as phenoli...

Finding an environment-friendly and affordable method to remove contaminated soils from Polycyclic Aromatic Hydrocarbons (PAHs) has now become an attractive field for researchers, with super-critical fluid extraction being an innovative process in the field of contaminated soil treatment. Extraction with super-critical fluid is a simple and rapid extraction process that uses super-critical flui...

Increases in ore mining, metal smelting activities, and several other industrial practices in recent times have brought about contamination of soils at higher levels; these have prompted concerns on the consequent effects on the local and global ecosystem. Various remediation technologies have often been sought to meet the challenges. This study therefore seeks to assess the potential of cashew...

phytoremediation has gained increasing attention in recent years because of its ability to clean up and redevelop brownfield sites. petroleum hydrocarbon-contaminated sites are among most prevalent industrial sites in iran as one of the top oil producers in the world, which are in great need of remediation to prevent associated environmental and human health risks. a greenhouse study was conduc...

Low-temperature plasma has exhibited high efficiency for fast remediation of organic-polluted soil with water content (less than 20%). In the present study, the feasibility of remediation of p-Nitrophenol (PNP) contaminated over-wet soil (water content of 100%) was studied using pulsed corona discharge plasma, which was generated in a needle-plate discharge reactor. Effect of energy input model...

Using plants for the remediation of soils contaminated with heavy metals is an economical, cheap, and effective strategy. The goal of this research was to study the effect of sewage sludge and drought stress on the remediation of cadmium in soil, root uptake by corn plant. This study was carried out on corn in factorial design experiment based on completely randomized design with three replicat...
