Background & Aims of the Study: Heavy metals contaminate drinking water, air and soils. It is very harmful for humans and other live organisms. Phytoremediation is one of the direct bio-remediation methods for heavy metal removal from polluted water and soils. This method is accepted environmentally, economically and aesthetically. The purpose of this study was to assess Tamari...
Abstract This paper reviews plants and microorganisms removal of heavy metals from contaminated sites through bioaccumulation. Increased industrial activities have led to the uncontrolled release into environment, resulting in a global increase metal pollution. Heavy are also consumed surface glasses over prolonged period use. pollution is serious problem that can wide-ranging long-lasting impa...
The importance of removal of heavy metals from drinking water has received significant attention of researchers and decision makers across the globe. Bio-adsorbents have emerged as potential remediation materials for the removal of heavy metals and metalloids from both groundwater and surface water. Plants, algae, fungi are some of the biomass derived adsorbents which are capable of removing he...
Background & objectives: The presence of heavy metals in urban sewage sludge limits its use as a soil modifier. The purpose of this study was to remove heavy metals (Cu, Zn, Cd and Pb) from urban sewage sludge using Acidophilic Thiobacillus ferrooxidans bacteria. Methods: In this experimental study, the sludge samples were collected from Shiraz wastewater treatment plant. Bioleaching tests were...
background: removing heavy metals from industrial wastewaters by iron nanoparticles has been much noticed in the recent years. chromium is considered as one of the emphasis environmental pollutants. there are high concentrations of chromium in the wastewater of electroplating industries. magnetic iron nanoparticles are used to control and eliminate the heavy metals from industrial effluents thr...
