Heavy Metals in Sewage Treated Effluents: Pollution and Microbial Bioremediation from Arid Regions
Not all heavy metals are toxic. Some at lower concentrations are essential to the physiological status of the organism. Under certain conditions, induced toxicity occurs when the heavy metals are in the form of cations which tends to bind to certain biomolecules, thus becoming toxic to organisms. In many industries, toxic heavy metals such as As, Cd, Cr, Cu, Hg, Pb and Zn, are released mainly i...
متن کاملAntibiotic resistant bacteria used as bioindicators of environmental pollution produced by tertiary treated sewage effluent
Oman depends on recycling treated wastewater as a solution to overcome the limited water supply. However, the risk of reusing recycled sewage water in the environment and public health is a major concern. Tertiary sewage treated effluent (TSE) was evaluated microbiologically from three sewage treatment plants (STPs). Mainly, all TSE from the three plants contained coliform and Escherichia coli....
متن کاملMercury pollution from irrigation with treated sewage water (TSW).
The lack of potable water in arid countries leads to the use of treated sewage water (TSW) for crop growth. Mercury accumulation (up to 500 ng/g) in agricultural soil originating from daily irrigation with TSW was found at two sites fed separately from a hospital sewage plant and an industrial plant. A control site irrigated with potable water ([Hg] <0.01 ng/ml) had much reduced levels in soil ...
متن کاملHeavy metal removal from municipal sewage sludges by phytoextractio
In European Union countries up to 80% of sewage sludge is used in agriculture and forestry, whereas in Poland only 11% is used as fertilizer. The principal environmental concern is the inevitable presence of heavy metals when using sewage sludge as fertilizer. The main objective of this study is to assess the effectiveness of the phytoextraction process in removing heavy metals from sludges. A ...
متن کاملHeavy metal pollution in intertidal sediments from Quanzhou Bay, China.
The concentrations of eight heavy metals (Cu, Zn, Pb, Cd, Cr, Ni, Hg, and As) in the intertidal surface sediments from Quanzhou Bay were determined to evaluate their levels and spatial distribution due to urbanization and economic development of Quanzhou region, southeast China. The ranges of the measured concentrations in the sediments are as follows: 24.8-119.7 mg/kg for Cu, 105.5-241.9 mg/kg...
