The current study assesses the effect of fibrous clay minerals’ amendments and arbuscular mycorrhiza incubation on heavy metal uptake and translocation in Eucalyptus grandis and Ailanthus altissima plants. For doing so, Eucalyptus and ailanthus trees have been grown in a soil sample, contaminated with heavy metal iron ore mining and collected from southern Iran. The area under study is arid, wi...

Heavy metals are notoriously toxic pollutants which can potentially harm living beings and serious health hazards. The aim of the present study was to assess levels cadmium (Cd) nickel (Ni) throughout year in urban areas densely populated industrial city Faisalabad eight commonly raised ornamental tree species with phytoremediation potential. High Cd Ni were recorded all areas, spatio-temporal ...

Nano-scale palladium was bio-manufactured via enzymatically-mediated deposition of Pd(II) from solution. The bio-accumulated metal palladium crystals were processed and applied onto carbon paper and tested as anodes in a proton exchange membrane (PEM) fuel cell for power production. Up to 85% and 31% of the maximum power generation was achieved by Bio-Pd catalysts made using two strains of bact...

Objective: this research investigates the concentration of heavy metal (Pb, Fe, Cu, Cd and Zn) bio accumulation in cardiac tissue samples taken from areas near oil fields brick factories. Method: Atomic absorption spectrometry analysis powdered, air-dried, acid-digested materials to determine lead, cadmium, zinc, iron, copper concentrations. Results: The result showed that Zn were within normal...

Heavy metals are among the most dangerous substances that cause pollution and accumulation in nature. The bio-sensitive way to decompose these pollutants is through adsorption studies with biopolymers. In this study, chitosan, one of common cost-effective biopolymers, was produced be employed aluminum lead, which have proven negative effects on living organisms. production stages shrimp crab sh...

The presented study aims to improve the quality of bio-oils by catalytic upgrading of pyrolysis bio-oil from microwave pyrolysis of biomass using transition metal modified activated carbon (AC) catalyst. A central composite experimental design (CCD) was used to optimize the reaction conditions for high quality bio-oil production. The effects of reaction temperature and reaction time on product ...

introduction: water shortage in arid and semiarid regions of the world is a cause of serious concerns. the severe water scarcity urges the reuse of treated wastewater effluent and marginal water as a resource for irrigation. mobarake steel complex has been using treated industrial wastewater for drip-irrigation of trees in about 1350 ha of its green space. however, wastewater may contain some a...

Phytomining of rare earth elements (REEs) provides a potential possibility for metal recovery at brownfields where conventional mining technique is not reasonable or profitable. The holistic concept phytomining instituted from three scientific sectors. Phytoextraction the first stage referred to accumulation REEs in plants. This followed by enrichment process aiming elevate concentration into s...

the objective of the present work is to analyse the potential of using non-classical additions in concrete and mortar compositions such as coal bottom ash (ba) and biomass ash (bio), as partial replacing binder of ordinary portland cement. it is intended to deal with production of these type of wastes and its accumulation and contribute to the minimisation of carbon and embodied energy in const...

Phytoremediation is a site remediation strategy, which employs plants to remove non-volatile and immisible soil contents. This sustainable and inexpensive process is emerging as a viable alternative to traditional contaminated land remediation methods. To enhance phytoremediation as a viable strategy, fast growing plants with high metal uptake ability and rapid biomass gain are needed. This pap...
