Lead (Pb), a ubiquitous but highly toxic heavy metal (HM), is harmful to human health through various pathways including by ingestion of contaminated vegetables. Radish is a worldwide root vegetable crop with significant health and nutritional benefits. However, little is known about Pb translocation and distribution within radish plants after its uptake by the roots. In this study, Pb stress w...

The effectiveness of nanoscale zero-valent iron (nZVI) to remove heavy metals from water is reduced by its low durability, poor mechanical strength, and tendency to form aggregates. A composite of zeolite and nanoscale zero-valent iron (Z–nZVI) overcomes these problems and shows good potential to remove Pb from water. FTIR spectra support nZVI loading onto the zeolite and reduced Fe0 oxidation ...

Results of in situ atomic force microscopy (AFM), ex situ AFM, optical microscopy, scanning electron microscopy, energy dispersive spectroscopy, and x-ray diffraction were combined with previous macroscopic investigations to characterize aqueous Pb(NO3)2 reaction with hydroxylapatite (Ca5(PO4)3OH) (HAP). Experiments were conducted by immersing particulate HAP crystals in the AFM fluid cell in s...

The lanthanide(III) complexes [Ln(LH2)(NO3)3] 1-11(La-Er), 15(Y) and [Ln(LH2)(NO3)2(H2O)](NO3) 12-14 (Tm-Lu) of the tetraiminodiphenolate macrocycle L2- have been prepared by the transmetallation reaction between [Pb(LH2)(NO3)2] and Ln(NO3)3.nH2O. In these compounds, the uncoordinated imino nitrogens are protonated and are hydrogen bonded to the phenolate oxygens. The X-ray crystal structures o...

the effects of industrial textile water(effluent water,ew) on soil, water and plant was investigated in this research. for conducting this research major important textile factory were selected and sampling was done in 2 stages and in 2 years. in each district and the control field (soil not irrigation with effluent water) the soils from 0-30 cm depth and plants were sampled in three replicates...

Assessments of groundwater pollution parameters were carried out in samples collected from selected shallow hand-dug wells across Ilora township. The analysed nitrate, trace elements including, iron, cobalt, chromium, manganese, zinc, arsenic, cadmium and lead, bacteria count water; using spectrophotometric method, HM Metalyser 5000 multiple tube techniques respectively. pH the was between 6.4 ...

Polymer-coated controlled-release fertilizers (PCFs) are the most widely used fertilizers in the production of container-grown nursery plants. The duration and magnitude of PCF nutrient release varies with product and this variation can significantly affect plant growth. Three experiments were conducted to determine the long-term nutrient release patterns of three PCFs (each with a rated longev...

Salisilik asit (SA), bitkilerde biyotik ve abiyotik stres kaynaklı birçok fizyolojik tepkiye aracılık eden önemli bir sinyal molekülüdür. Bu çalışmada, faklı konsantrasyonlarda kurşun [Pb(NO3)2] stresine maruz bırakılan 5 BB, 41 B 1103 P Amerikan asma anaçlarında değişen dozlardaki SA uygulamalarının morfolojik, biyokimyasal özellikler üzerine etkileri incelenmiştir. Dikimden 6 hafta sonra 0, 1...
