Abstract This study investigates the effectiveness of using nanoscale zero‐valent iron (nZVI) to immobilise Pb/Zn in two different soils (acidic and calcareous) effects nZVI treatment on soil physico‐chemical biological properties. Soil samples spiked with Pb(II) or Zn(II) were treated commercial suspension at a dose 20% (28–36 mg Fe(0)/g soil) for 72 h one month. Sequential extraction procedures showed significant decrease bound exchangeable carbonate fractions an increase residual fraction...

ABSTRACT Two Salix genotypes (Salix alba, clone LUC-31—genotype I and viminalis, STOTT—genotype II) were grown hydroponically for 14 d at increasing concentrations of cadmium (Cd) (0, 5, 10, 15 μM) in order to study both Cd accumulation genotype tolerance. Growth responses, photosynthetic performance, activities metal-responsive enzymes, changes some nutrients content used as evaluation criteria. The Genotype II assimilated more (maximum leaf concentration 47.8± 2.9 mg kg−1 DW) compared with...

The tolerance of the metallophyte Silene vulgaris, a plant suitable for phytostabilisation metal(loid)-contaminated soils, to arsenic (As), mercury (Hg) and cadmium (Cd) was evaluated in semi-hydroponic culture system under controlled environmental conditions. appearance oxidative stress, alteration photochemical processes modification biothiol content were studied as physiological parameters metal(loid) stress plants treated with 0, 6 30 μM (As, Hg or Cd) 7 days. In spite excluder behaviour...

Plant growth promoting endophytic bacteria (PGPB) isolated from Brassica napus were inoculated in two cultivars of Helianthus tuberosus (VR and D19) growing on sand supplemented with 0.1 mM Cd or 1 Zn. growth, concentrations metals thiobarbituric acid (TBA) reactive compounds determined. Colonization roots H. D19 by Pseudomonas sp. 262 was evaluated using confocal laser scanning microscopy. 228, Serratia 246 significantly enhanced exposed to 228 increased roots. 246, 256 resulted decreased...

Abstract The conversion of an agroforestry based agricultural system to a monocropping farming influences the distribution and composition arbuscular mycorrhizal fungi (AMF). aim this paper was analyze AMF species diversity, spore density, root colonization across different practices (AFP) in southern Ethiopia. Soil samples were collected from homegarden, cropland, woodlot, trees on soil water conservation-based AFP. spores extracted diversity evaluated using morphological analysis samples....

Land degradation in Ethiopia is escalating due to high population density and the shift from tree-based agricultural systems, like agroforestry practices (AFP), monoculture farming. These land use changes, compounded by climate change, threaten biodiversity soil resources. Key health parameters, such as glomalin, aggregation, aggregate stability, are negatively impacted practices. Agroforestry proposed a sustainable alternative address these challenges. This study aimed evaluate effects of...

Chromium released into the environment from industrial activities has become an important environmental concern. Silene vulgaris been proven to be tolerant many heavy metals, so it is considered interesting species in revegetation and restoration of polluted soils, but no information available about its response Cr. The objective this work was study uptake influence on plant growth Cr(III) Cr(VI) six genotypes (four hermaphrodites two females) S. different sites Madrid (Spain). Plants were...

Phytomanagement could be a viable alternative in areas polluted with wastes from chromium-using industries. This study investigated the ability of Silene vulgaris to take up Cr(III) and Cr(VI) special attention on mechanism used by this species tolerate high doses Cr(VI). Plants were grown semihydroponically different concentrations either or A combination synchrotron X-ray spectroscopic techniques, scanning electron light microscopy infrared spectroscopy determine distribution speciation...

Mine waste constitutes one of the biggest environmental and management problems, both due to its quantity danger when they are rich in toxic elements. There is a wide variety from oxidation ores metal mining areas, sulphide other minerals. These residues may be enriched potentially elements that can spread contaminate ecosystems, farmland villages. This study has focused on characterization evaluation derived metal-bearing abandoned areas. Mineralogy geochemical characteristics were...

The effect of five washing treatments (unwashed, water washed, Tween 80 0.1 M HCl acid and 80-acid washed) is evaluated to remove nutrient element deposits from orange peach leaves. Untreated leaves sprayed with a seaweed extract iron fertilizer in two dosages are compared. Micronutrients were more affected by the procedures than macronutrients. Acid detergent was most efficient, especially as regards micronutrients (Fe), manganese (Mn), zinc (Zn). Copper (Cu) did not seem be influenced...

In the present study, mineral composition of seventy-one bee pollen samples from four different apiaries was determined by means inductively coupled plasma-optical emission spectrometry. The results showed that there were no significant differences in relation to overall content per sample terms apiary origin or harvesting period; most common elements phosphorus and potassium with concentrations ranging 2.3 5.1 g/kg (dry weight). Moreover, analyzed similar higher than recommended as...

The interaction between plant growth-promoting bacteria (PGPB) and plants can enhance biomass production metal tolerance of the host plants. This work aimed at isolating characterizing cultivable bacterial community associated with Brassica napus growing on a Zn-contaminated site, for selecting PGPB that might energy crops. effects some these strains root growth B. exposed to increasing Zn Cd concentrations were assessed. A total 426 morphologically different isolated from soil, rhizosphere,...

ABSTRACT Woody cuttings from two Salix genotypes (genotype I—clone LUC-31, alba and genotype II- clone STOTT, viminalis) were grown hydroponically for 14 days at increasing concentrations of Zn: control, 50, 100 or 150 μ M Zn. Genotype tolerance to excess zinc (Zn) was evaluated using a root elongation test. The changes in growth, Zn, iron (Fe), copper (Cu) manganese (Mn) as well photosynthetic performance used additional evaluation criteria. Photosynthetic pigments Zn-exposed II decreased...
