Heavy metal contamination in the environment could cause harmful effects both to human health and aquatic life. Numerous remediation methods had been developed to encounter with the contamination problem prior to degrade, decrease and to purify the contaminated water at minimal concentration as low as possible. Therefore, in current study, commercialized chicken eggshells and hybrid Akar Pu...

introduction with the rapid development of industries such as metal plating facilities, mining, fertilizer producing industries, tanneries and paper industries heavy metals enriched wastewaters are directly or indirectly discharged into the environment. zinc is a trace element that is essential for human health. it is important for the physiological functions of living tissues and regulates man...

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 ...

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,...

Heavy metal pollution represents an important environmental problem due to the toxic effects of metals. Their accumulation throughout the food chain leads to serious ecological and health problems. The remediation of environments metal contaminated through physico-chemical methods present major disadvantages such as high energy consumption, high costs and incomplete removal of metal ions. Bioso...

Presence of heavy metal ions in wastewater is an important public concern. Adsorption are commonly used technique to remove various pollutants, including the ions, from contaminated water sources. However, common methods for adsorption are not completely efficient at low ion concentrations and the adsorbent should be improved in order to reaching the acceptable levels of adsorption efficiency. ...
