The effects of arbuscular mycorrhizal (AM) fungus (Glomus mosseae) and phosphorus (P) addition (100 mg/kg soil) on arsenic (As) uptake by maize plants (Zea mays L.) from an As-contaminated soil were examined in a glasshouse experiment. Non-mycorrhizal and zero-P addition controls were included. Plant biomass and concentrations and uptake of As, P, and other nutrients, AM colonization, root leng...

Soil contamination with toxic metals resulting from global industrialization is a serious environmental issue. Industrial activities such as mining of ore, discharge wastewater, excess application fertilizer and pesticide have led to environment heavy cadmium, lead, mercury, copper, arsenic, zinc etc. Complete degradation not possible thus they continuously accumulate in the leading great threa...

Abstract Toxic metal contamination of soil is a major environmental hazard. Chemical methods for heavy metal's (HMs) decontamination such as heat treatment, electroremediation, replacement, precipitation and chemical leaching are generally very costly not be applicable to agricultural lands. However, many strategies being used restore polluted environments. Among these, phytoremediation promisi...

Abandoned lead and zinc (Pb/Zn) mining wastes represent a serious environmental hazard because heavy metals (e.g., Pb Cd) are continuously released into the environment, threatening ecological human health. This study was devoted to investigate stability of Cd in soil at an abandoned Pb/Zn mine site after landscape restoration by five-year monitoring. Chemical extraction applied measure distrib...

The plant species Pinus halepensis grows spontaneously on heavily polluted mine tailings dumps of Campo Pisano (Sardinia, southwestern Italy). area is characterized mainly by Zn, Pb, and Cd. Sampling campaign was done, related to soils materials (roots, barks, wood, needles), aimed at evaluating the main mineralogical characteristics, metal content, accumulation, translocation behavior. substra...

Because of their high content in toxic metals, steel slag dumps are potential threats for the environment and public health. Among management methods that could mitigate hazard, aided-phytostabilization is a relevant, though challenging, option. Indeed, slags very unfavorable plant growth, due to metal toxicity alkaline pH (>10). In this work, we investigated how composted sewage sludge allevia...

The aim of the study was to compare phytoremediation potential cultivated grasses with local wild grass for soil contaminated zinc. Two pot experiments were carried out on artificially Zn. Four species used as test plants: Poa pratensis, Lolium perenne, Festuca rubra, and one wild, native grass: Deschampsia caespitosa. Wild seeds collected from heavy metals near a zinc smelter. determined basis...
