Soil heavy metals have been a very useful indicator of environmental quality worldwide. The present study was conducted to investigate the levels, sources, distribution and spatial variability of heavy metals (Cu, Mn, Cd, Pb, and Zn) in soils in close proximity to an industrial area. Hierarchical Cluster Analysis (HCA) was applied to test the similarities between sampled elements based on neare...

The fly ash is a cheap waste materials which can be an efficient substrate in wastewater treatment for the immobilization of heavy metals, mainly Cd, Pb, Ni, Zn, Cu, and for dyes removal. The use of FA for heavy metals removal, from wastewaters resulted in the dye finishing industry, faces a supplementary problem, related to the dyes affinity for oxide surfaces. Working with industrial wastewat...

The bean (Phaseolus vulgaris) stress-related gene number 2 (PvSR2) gene responds to heavy metals but not to other forms of environmental stresses. To elucidate its heavy metal-regulatory mechanism at the transcriptional level, we isolated and characterized the promoter region (-1623/+48) of PvSR2. Deletions from the 5' end revealed that a sequence between -222 and -147 relative to the transcrip...

This paper builds a bridge between heavy metal music, complexity theory and sustainability science to show the potential of the (auditory) arts to inform different aspects of complex systems of people and nature. The links are described along different dimensions. This first dimension focuses on the scientific aspect of heavy metal. It uses complex adaptive systems theory to show that the rapid...

In this study, biosorption of heavy metal and dye by microbes will investigate. Optimum pH values of the maximum heavy metal biosorption will be finding. The bioremoval of the dye also investigate at different pH, Removal rates will measure respectively. The presence of heavy metal with dye analysis will be done for uptake by biosorbents .The results expected to indicate that the isolated bioso...

abstract lettuce is one of the best accumulators of heavy metals and nitrate between leafy vegetables. through this research, it was tried to decreased cadmium absorption with humic acid (ha) and studies the effect of ha on the accumulation and metabolism of nitrate. plants were grown in the peat/perlite and irrigated with hoagland solution with addition of cadmium (2 and 4 mg l -1) and ha (100...

background: there has been increasing awareness throughout the world regarding the remarkable decrease in amphibian population. for such amphibian population decline several causes have been given. cadmium, a heavy metal is released both from natural sources (leaching of cadmium rich soils) and anthropogenic activities to the aquatic and terrestrial environments. this study evaluated the toxici...

plant biomass harvested after heavy-metal phytoremediation must be considered as a hazardous waste that should be contained or treated appropriately before disposal or reuse. this study provides an evaluation of extractants for the removal of lead from abutilon theophrastus biomass. the research was carried out a leaching study to determine the lead-extraction efficiency of the different leacha...

plants are the most common bioindicatorsused in air quality biomonitoring studies because they are immobile and they have more sensitive to the most prevalent air pollutants than humans and animals. to identify the concentrations and sources of heavy metals in ornamental plants of isfahan landscape, samples of leaves and soil around pinuseldarica and nerium oleander were collected at different ...

in current work, cds/black carbon nanocomposites were successfully synthesized with the aid of chestnut and cadmium nitrate as the starting reagents. besides, the effects of preparation parameters such as reaction time, and precursor concentration on the morphology of products and removal of heavy metals (hg+2, pb+2) were studied by scanning electron microscopy images and batch adsorption mode....
