A microwave process can be utilized to stabilize the copper ions in heavy metal sludge. The effects of microwave processing on stabilization of heavy metal sludge were studied as a function of additive, power, process time, reaction atmosphere, cooling gas, organic substance, and temperature. Copper leach resistance increased with addition of aluminum metal powder, with increased microwave powe...

This study aimed to evaluate the concentration of heavy metals in liquid effluents and to quantify the mercury content in dental amalgam waste generated by dental clinics. Three neighbouring cities in Northeast Algeria were considered in this study (Constantine, Skikda, and Annaba). Heavy metals, such as Hg, Cu, Zn, Fe, Ni, Mn, Cr, Cd, and Pb, were analysed in wastewater and then compared with ...

background and objectives: despite the increasing impact of heavy metal pollution in persian gulf due to urban growth and agricultural and petroleum activities, few studies have focused on the behavior and relationships of these pollutants in the biotic and abiotic components of aquatic environments. in this study, the amount of some metals (copper, iron, lead, cadmium, zinc and nickel) was det...

Oxidative stress is induced by a wide range of environmental factors including heavy metals stress. Therefore, antioxidant resistance mechanisms may provide a strategy to enhance metal tolerance, and processes underlying antioxidant responses to metal stress must be clearly understood. In the present study, the effects of heavy metals generating antioxidative defense systems (i.e. superoxide di...

The present study was designed to evaluate the heavy metal absorbing potential of bacteria isolated from industry effluent sites of river Nagavali, Srikakulam Andhra Pradesh. From the effluent waste water three bacteria were isolated and confirmed as Staphylococcus aureus and Staphylococcus epidermidis and Staphylococcus saprophyticus after performing various biochemical tests. The heavy metal ...

The present study was aimed at comparing the ability of three crop plants for phytoremediation of zinc (Zn) and nickel (Zn) from soils. A factorial (3×2×3) experiment based on RCBD was used to compare the treatments, and was repeated three times. The first factor was crop type (wheat, clover and rapeseed), the second factor was heavy metal types (zinc (Zn) and nickel (Ni)) and the third factor ...

background and aims: the removing of (potential) toxic heavy metal ions from sewage, especially in industrial and mining waste effluents, has been widely studied in recent years. the aim of present study was to investigate the various methods for lead removal of lead ions from industrial wastewater. methods: this study was a review research. data were collected through different databases in va...

nickel (ni) is a heavy metal and soil pollutant but existence of small amount of it as a metallic part of urease enzyme in the plants is necessary. remediation of spots contaminated with heavy metals is particularly challenging. phytoremediation, the use of plants for environmental restoration, is a novel clean up technology. in this study, five levels of nickel [control (ni0), ni125, ni250, ni...

environmental stresses are one of the most important factors of agricultural products reduction in the world. the influence of different concentrations of nickel nitrate (0, 100, 200 and 500 μm in hoagland’s solution) on dry matter, catalase enzyme, flavonoids, hydrogen peroxide, peroxidase enzyme, mda and accumulation of ni were studied in coriander ( coriandrum sativum ) plants. treatment wit...
