Opis:
Concentration of seven (7) metals (Pb, Cu, Zn, Mu, Ni, Cr, and Cd) in the samples of soil and some plant species collected from Kachia military shooting range were determined. The mineral ions were assayed using the acid digestion method and atomic absorption spectrophotometry (AAS). Physicochemical parameters (pH, EC, Bulk density, water holding capacity and Total Nitrogen) of the soil samples were also determined. Of the 7 metals determined in the soils samples, the concentration of Pb (14.85 ± 6.78 mg/kg-1) was the highest compared to the concentrations of other metals. Physicochemical parameters were within the range that allows effective phytoremediation. Cu showed the lowest concentration (0.55 ± 1.68 mg/kg-1). Ni was below the detectable limit in most of the samples. Similarly, concentrations of Pb (12.30 mg/kg-1) in the shoot of Albizia zygia among other metals were higher than those of the other metals in the plant tissues. Concentration of Cd (0.07 mg/kg-1) in the root of Eragotis tremula was the lowest. Generally, metal ion concentration in the soil and plant samples of the shooting range (polluted site) significantly) differed from those of the non-polluted site (P<0.05). Combretum hispidium among the plant species had the highest translocation factor (TF = 2.91). Although the TF was higher in the plant of the polluted site TF >1), reasonable amount of them were retained within the underground tissues (roots).

Opis:
The present study was conducted to evaluate the insecticidal efficiency and safety of zinc oxide nanoparticles (ZnO NPs) and hydrophilic silica nanoparticles (SiO2 NPs) against: adults of rice weevil (Sitophilus oryzae L.); red flour beetle (Tribolium castaneum Herbst.) and cowpea beetle (Callosobruchus maculatus F.) results showed that, both ZnO NPs and hydrophilic SiO2 NPs exhibited a significant toxic effect (df, F and p < 0.5) against S. oryzae and C. maculatus at the highest concentration while T. castaneum showed high resistance against the two tested materials. At the end of the experiment, recorded mortality was: 81.6, 98.3 and 58.3% at the highest concentration used for each insect (0.3, 2 and 8 gm ⋅ kg–1 of SNPs with C. maculatus, S. oryzae and T. castaneum, respectively), while mortality was 88.3, 100 and 38.3% at the highest concentration used for each insect (0.6, 2.5 and 8 gm ⋅ kg–1 of ZnO NPs with C. maculatus, S. oryzae and T. castaneum, respectively). Both tested materials caused high reductions in F1-progeny (%) with C. maculatus and S. oryzae. Histopathological examination of male mice livers showed hepatic architecture with congested blood sinusoids, binucleated hepatocytes nuclei, dilated central vein and margainated chromatin in some nuclei. Histopathological assessment of the lungs showed normal histoarchitecture. There were no differences in alveolar septa, bronchiolar and epithelium of the treated and untreated animals. Silica and zinc oxide nanoparticles have a good potential to be used as stored seed protectant alternatives if applied with proper safety precautions.
