Pollution of agricultural soil with heavy metals is a serious hazard to the environment and human health. The application biochar can be cost-effective environmentally friendly way reduce metal bioavailability in contaminated soils thus their uptake by plants. A pot experiment was conducted evaluate effect three types (mango, Casuarina Salix as feedstocks) at two rates (2% 4% w/w) on characteristics, availability bioaccumulation plants, well growth summer squash grown highly polluted soil....
Abstract There is lack of information available concerning the effect humic substances (HS) applied via fertigation on plant growth in sandy soils. Therefore, a field experiment was carried out at El‐Saff district (20 km southwest Cairo), Egypt, to investigate role HS water retention soil, yield and quality broccoli ( Broccoli oleracea L.) as well soil nutrient concentration retained after harvest. The consisted six treatments (50%, 75%, 100% recommended NPK‐fertilizer rate for combined with...
Mangroves play an integral role as a metal accumulator in tropical and subtropical marine ecosystems. Twenty-one sets of sediment samples portions mangroves were collected along the Saudi Arabian coast Red Sea to assess accumulation ecological risks heavy metals. Results showed that following mean concentrations metals sediments: Cr (46.14 μg g−1 ± 18.48) > Cu (22.87 13.60) Ni (21.11 3.2) Pb (3.82 2.46) Cd (0.75 0.87). The maximum studied above threshold effect level, indicating limited...
Since the early 1990s, soil electrokinetic remediation (SEKR) has been exploited for removing organic, inorganic, and radioactive material from contaminated soil. However, application of SEKR met with multiple obstacles; thus, trials have introduced to overcome these limitations. The present study provides a comprehensive review various modifications applied process designs. We classified designs in horizontal, vertical, mixed (horizontal vertical) types as per movement contaminants. is...
Heavy metal pollution of agricultural soil has become a major serious concern. The development suitable control and remediation strategies for heavy contaminated critical. outdoor pot experiment was conducted to investigate the effect biochar, zeolite, mycorrhiza on bioavailability reduction metals its subsequent effects properties bioaccumulation in plants as well growth cowpea grown highly polluted soil. Zeolite, mycorrhiza, zeolite with biochar without any modifications were six...
Adsorption of Cd 2+ on two types Egyptian soils: clay (alluvial) and sandy loam (calcareous), was studied. Effect changing the matrix electrolyte type concentration used to mimic natural soil salts. Kinetics thermodynamic parameters adsorption were calculated at different concentrations: 0.05 N 0.15 N. The described by Langmuir Freundlich isotherms. Results showed that lower NaCl or Na 2 SO 4 electrolytes (0.05 N) had higher capacity. Also, maximum cadmium when using sulfate counter ion is...
The accumulation of trace metals in vegetable field soils is increasing worry because the potential health hazards and their detrimental effects on soil ecosystems. To investigate state metal pollution soils, 60 surface samples were collected from fields across Eastern Nile Delta region, Egypt. results concluded that concentrations Cu, Mn, Ni lesser than corresponding background values, while Cd, Co, Pb, Zn exceeding values. indices showed studied experienced low to moderate contamination Cd...
Abstract To assess trace element concentrations (Zn, Cu, Pb, Cr, Cd and Ni) in the mangrove swamps along Saudi coast of Arabian Gulf, thirteen samples surface sediment leaves grey mangrove, Avicennia marina were collected analyzed. The detected contents (μg g -1 ) sediments following descending order according to their mean values; Cr (49.18) > Zn (48.48) Cu (43.06) Pb (26.61) Ni (22.88) (3.21). results showed that average exceeded world concentration shale. geo-accumulation, potential...
Biochar derived from agricultural byproducts is increasingly being recognized as a promising adsorbent material for wastewater remediation. This research evaluating the effect of chemical treatment solutions on activating sorption capacity biochar cotton stalks. The surface characteristics chemically modified (CMB) were investigated with scanning electron microscopy equipped energy dispersive X-ray spectroscopy (SEM-EDS) and Fourier Transform Infrared (FTIR) spectroscopy. Using batch...
Mangrove shrub Avicennia marina (Forsk.) Vierh was used to test the antifungal and antibacterial activities of aerial fractions in vitro. Aspergillus sp, Candida sp Gram positive bacteria have all been found be sensitive mangrove extracts, whereas negative resistant them. Agar disc diffusion well-cut were employed conduct activities. The MICs (minimum inhibitory concentrations) for each assay established. Several extracts from reduced fungus growth (diameters fluctuated between 11 41 mm)....
AbstractCommon bean (Phaseolus vulgaris L.) can supply all of the iron that humans require for metabolism. Also, it fixes atmospheric nitrogen (N2) in symbiosis with rhizobia. In order to analyze relation between phosphorus (P) and (Fe) elements nodules their roles plant N2-dependent growth, six common recombinant inbred lines (RIL) cross BAT477 DOR364 were inoculated Rhizobium tropici CIAT 899 (originating from International Center Tropical Agriculture, Colombia) grown sufficiency versus...
