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...

introduction: biosorption of heavy metals can be an effective process for the removal of heavy metal ions from aqueous solutions. also, living lichens are known to accumulate metals across their surface. materials and methods: in this study, the biosorption of cadmium ions cd (ii) by the lichens acarospora strigata, lecanora muralis and caloplaca aurantia was investigated in aqueous solution in...

Chromium is a heavy metal toxic for plants that due extensive industrial applications over the last decade, has become a serious environmental pollution. On the other hand, chelator dissolution and absorption of metal by the plant increase and their use in phytoremediation is important. The aim of this study was to evaluate the effect of different concentrations of chromium and ethylene diamine...

In recent years, heavy metal toxicity related to the use of traditional Chinese and Indian herbal medications has been reported in a number of countries, including Australia. Heavy metals such as lead or mercury may be introduced into herbal medications through contaminated soil or production techniques, or may be deliberately included as a therapeutic ingredient. Particularly when consumed ove...

Industrial activities and high traffic density are the most important heavy metal pollution sources in urban areas. Roadside dust created by atmospheric deposition can be one of the best indicators for heavy metal contamination levels. The present study reports the spatial distribution patterns and degree of heavy metal pollution (Cd, Cr, Ni, Pb, Zn, and As) in 50 roadside dust samples from urb...

this study at first level focused on definitions and descriptions of  some landfills and landfills sites all around the world and  survey on how important they are for regional governments and responsible in duty  as a very important responsibility for locals and their health. at the second level we had a look on heavy metals concentration which are by many definitions as follows: lead, nickel,...

The effect of 24-epibrassinolide (24-epiBL) on seedling growth, metal uptake and accumulation were investigated in seedlings of Brassica juncea L. cv. PBR 91. Seeds of B. juncea treated with different concentrations (0, 10-7, 10-9 and 10-11 M) of 24-epiBL for 8 h were subjected to various concentrations (0, 25, 50 and 100 mg l-1) of heavy metals (Zn, Mn, Co and Ni). Seedling growth was improved...
