phytoextraction is a remediation technology for contaminated soils with lead (pb). the application of chelating agents can be resulted in high efficiency in this method. in current study, the effect of synthetic and natural chelates applicationon efficiency of lead phytoextraction from soil by carrot was investigated. the experiment factors were 1) six levels of pb (0, 100, 200, 300, 500 and 80...

The combination of surfactant enhanced soil washing and degradation of nitrobenzene (NB) in effluent with persulfate was investigated to remediate NB contaminated soil. Aqueous solution of sodium dodecylbenzenesulfonate (SDBS, 24.0 mmol L-1) was used at a given mass ratio of solution to soil (20:1) to extract NB contaminated soil (47.3 mg kg-1), resulting in NB desorption removal efficient of 7...

A novel, cost-effective and eco-friendly technologies are needed to remove Zinc from the contaminated soil environment. The present research study was designed to assess the naturally enhanced phytoextration and phytostabilization potential of different plant species from the Zinc (II) contaminated soil. Uptake of Zinc by plant species in a metal contaminated soil was studied in pot culture exp...

Degradation of phenol and polycyclic aromatics hydrocarbons (PAHs) presented in artificially contaminated and/or real soil collected from a contaminated site of former coke plant by free cells of Candida tropicalis was studied in batch cultures and at the ratio of liquid culture media : soil = 2 : 1 with the initial concentration of phenol 560 mg kg -1 and 152 mg kg -1 (real soil), respectively...

Mechanochemical treatment, or high energy ball milling, was successfully employed to destroy per- and polyfluoroalkyl substances in an aqueous film-forming foam concentrate authentic contaminated soil sample.

The aim of the studies was to compare the composition of soil bacterial metabiomes originating from urbanized areas and areas con¬taminated with hydrocarbons with those from agricultural soil and forest soil obtained from a protected wild-life park area. It should be noted that hydrocarbons are everywhere therefore bacteria capable of their utilization are present in every soil type. In the hyd...

To assess soil and groundwater quality two generic (i.e. multifunctional) risk-based standards, Target and Intervention Value, have been developed, in the framework of the Dutch Soil Protection Act. These standards allow soil and groundwater to be classified as clean, slightly contaminated or seriously contaminated. The Target Value is based on potential risks to ecosystems, while the Intervent...

One DDT-contaminated soil and two uncontaminated soils were used to enumerate DDT-resistant microbes (bacteria, actinomycetes and fungi) by using soil dilution agar plates in media either with 150 mg DDT ml−1 or without DDT at different temperatures (25, 37 and 55◦C). Microbial populations in this study were significantly (p<0.001) affected by DDT in the growth medium. However, the numbers of m...
