Removal of heavy metals from treated wastewater using natural growing plants on River Nile banks in Egypt
Batch experiments using two types of aquatic plants named Echinochloa pyramidalis, Ludwigia stolonifera planted in association and individually. Reference experiments without aquatic plants were carried out. All experiments were for 10 days retention time for the removal of cadmium (Cd), nickel (Ni) and lead (Pb) from secondary treated wastewater. Electrical conductivity (EC), pH values, total dissolved solids (TDS), nitrite – ... إقراء المزيد

A comparative study for the effect of nano-sized Moringa oleifera and Delonix regia for removal heavy ions from water
The ability of natural biosorbents for removing heavy metal ionswere investigated by studying the effect of nano sized _Delonixregia _and _Moringa__ oleifera_on adsorption of Cd2+and Pb2+ions from aqueous solution. The investigated biosorbents (_Delonixregia_and _Moringa__oleifera)_ were characterized by FT-IR, SEM, TEM, XRD and EDS techniques.The influence of pH, temperature, adsorbent dosage, contact time and initial metal ion concentration on adsorption process ... إقراء المزيد

Biosorption of aluminum, cobalt, and copper ions by Providencia rettgeri isolated from wastewater
Twenty three bacterial isolates from polluted water and soil were screened for heavy metals resistance (i.e. Al(3+) , Co(2+) and Cu(2+) ). The most potent isolate was identified by morphological characteristics, biochemical tests and confirmed by API20E kits as Providencia rettgeri MAM-4. Removal of Al(3+) from aqueous solution by P. rettgeri is more efficient (∼4-fold) than that by B. cereus ... إقراء المزيد

BIOMAGENTIC MONITORING OF AIR POLLUTION USING DUST PARTICLES OF URBAN TREE LEAVES AT UPPER EGYPT
Six common tree species were used to check their suitability to use as magnetic biomonitors for particulate air pollution. The morphology and chemical composition of their leaf dust were identified using SEM/EDX. The results showed that the shape of particles are sphers, ovoid, irregular or grouped into aggregates; they were well within the size range of urban dust, especially hazardous ... إقراء المزيد

PHYSIOLOGICAL RESPONSE OF EUCALYPTUS ROSTRATA TO HEAVY METAL AIR POLLUTION
The physiological response of Eucalyptus rostrata due to exposure to heavy metal air pollutants was investigated. The heavy metals Cu, Cd, Fe, and Pb were applied to the above ground parts of the plants, under greenhouse conditions. The metal contents were proportional to the metal concentration in the sprayed solutions. Increasing sprayed metal concentrations was found to have an important ... إقراء المزيد

Heavy metal biomonitoring and phytoremediation potentialities of aquatic macrophytes in River Nile
The concentrations of Cd, Cu, Pb, and Zn in sediments, water, and different plant organs of six aquatic vascular plant species, _Ceratophyllum demersum_ L. _Echinochloa pyramidalis_ (Lam.) Hitchc. & Chase; _Eichhornia crassipes_ (Mart.) Solms-Laub; _Myriophyllum spicatum_ L.; _Phragmites australis_ (Cav.) Trin. ex Steud; and _Typha domingensis_ (Pers.) Poir. ex Steud, growing naturally in the Nile system (Sohag Governorate), were investigated. ... إقراء المزيد

Functionalization of magnetic Nano Particles: synthesis, characterization and their Application in water purification
Contamination of fresh and marine sediments and water environments by oil spills, urban runoffs, industrial and domestic effluents is demonstrating to be of critical concern as the presence of contaminants affects aquatic organisms and can quickly disperse to large as highlighted by the recent Gulf oil spill disaster. Polycyclic aromatic hydrocarbons (PAHs), Poly chlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane (DDT) and heavy ... إقراء المزيد

Response of Antioxidant Enzymes in Pyrchantha Coccnia as Biomarkers for the Detection of Pb in Urban Atmosphere
The utility of antioxidant enzymes, via superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX) and glutathione peroxidase (GPX), as biomarkers of lead pollution in urban atmosphere of Baku was investigated by using the Pyrchantha coccnia. At higher lead concentrations (105.74 ppm), CAT, SOD, APX and GPX exhibited remarkable induction (22.9968, 3.3664, 3.324 and 81.318 unit g-1 FW, respectively) with increasing ... إقراء المزيد
