Research ArticleOpen accessIn the abstractSalicylic Acid Protects Nitrate Reductase Activity, Growth and Proline in Amaranth and Tomato Plants during Water DeficitC. E. Umebese, T. O. Olatimilehin, T. A. OgunsusiProblem statement: Seedlings of Amaranthus hybridus cv. NHAC-3 (large green, amaranth) and Lycopersicum esculentum cv. Roma (tomato) were subjected to 7 days water stress at Early Vegetative (EV), Late Vegetative (LV), Early Flowering (EF) and Late Flowering (LF) stages of growth to study the impact on leaf water potential (ψw), Nitrate Reductase Activity (NRA), growth (plant height, shoot and root … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 9,565 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDetoxification of Heavy Metal Contaminated SoilsFloarea Damian, Gheorghe DamianThe concentration of the heavy metals in the soils from the strong affected zones because of the mining and metallurgical industry, Baia Mare and Zlatna (Romania), is significant due to the high values of the contents and association of the four metals Pb, Cu, Zn, Cd. The efficacy of the natural zeolites in heavy metals immobilization from the studied soils … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 7,233 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEnergetic Aspects Related to Heavy Metals Adsorption on the Surface of Volcanic Tuff I. The Influence of Activation Parameters in Cu2+ AdsorptionLeonard Mihaly-Cozmuta, Teodor Visan, Anca Mihaly-Cozmuta et al.The article develops some physico-chemical aspects presented along of copper ions adsorption in treatment of wastewaters using volcanic tuff. In the experiments volcanic tuff from Stoiana Pâglişa (Romania) has been used. Different concentrations of NaCl and HCl solutions were used for activation of tuff. The increase of activation solutions' concentrations indicates an intensification of specific adsorption of copper as consequence … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,666 accessesView PDF Cite
