Polycyclic aromatic hydrocarbons (PAHs) and metals are contaminants of industrial brownfield soils. Pollutants can have harmful effects on fungi, which major actors soil functioning. Our objective was to highlight fungal selection following long-term contamination Fungal diversity assessed 30 top-soil samples from ten sites gathered in three groups with different levels physico-chemical charact...

Whether it is for risk assessment or remediation purpose, contaminant availability in polluted soils a key parameter to determine. Two methods were recently standardized the estimation of environmental available fraction non-polar organics but, some cases, their application on real historically contaminated does not provide satisfactory results. The present study aimed at proposing an alternati...

Polycyclic aromatic hydrocarbons (PAHs) are major pollutants globally and due to their carcinogenic and mutagenic properties their clean-up is paramount. Bioremediation or using PAH degrading microorganisms (mainly bacteria) to degrade the pollutants represents cheap, effective methods. These PAH degraders harbor functional genes which help microorganisms use PAHs as source of food and energy. ...

The metals contamination in surface soils and their accumulation in wild plants from the abandoned Burra and Kapunda copper mines located in South Australia were assessed, and the predominant bacterial diversity in the contaminated surface soils from these two abandoned copper mine sites were evaluated through polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) analysis...

The cultivable fungal diversity from PAH-contaminated sediments was examined for the tolerance to polycyclic aromatic hydrocarbon (PAH). 85 strains, isolated in non-selective media, revealed a large by ribosomal internal transcribed spacer (ITS) sequencing, even including possible new species. Most strains (64%) exhibited PAH-tolerance, indicating that retain diverse PAH-tolerant fungi. PAH-tol...

Microorganisms (17 bacteria and 3 fungi) isolated from crude oil-contaminated soils were evaluated for degradation of five polyaromatic hydrocarbons (PAHs), both in the absence (-T80) presence surfactant Tween-80 (+T80) at a 10 mg L?1 concentration each PAH. Results heat map Tukey HSD revealed that highest PAH was observed by Kocuria rosea +T80 treatment. Degradation (%) individual (-T80, +T80)...

The aim of this study was to investigate the potential utility of ethanol washing for remediating soils contaminated with polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs), as a cost-efficient alternative to conventional remediation methods of PCDD/F-contaminated soils. Initially, screening experiments were performed with a two-level full factorial design to ex...

In many countries cadmium (Cd) and arsenic (As) commonly coexist in soils contaminated by mining activities, and can easily enter the human body via consumption of leafy vegetables, like the popularly consumed pakchoi (Brassica chinensis L.), causing major health concerns. In the present study, bioaccessibility and human exposure of Cd and As were assessed in twenty genotypes of pakchoi culture...
