    Condition: Hervorragend. Zustand: Hervorragend | Sprache: Deutsch | Produktart: Bücher | Pflanzen sind nicht nur für essenzielle Nährstoffe vollkommen selektiv. Sie sind in der Lage, beträchtliche Mengen an Schadstoffen wie Schwermetallen aus der Umwelt (Boden, Wasser oder Luft) aufzunehmen. Infolgedessen können Menschen und Tiere, die solche Pflanzen nutzen, erhebliche Mengen an Schadstoffen in den verschiedenen Teilen ihres Gewebesystems anreichern. Aufgrund der möglichen Toxizität von Schadstoffen leiden die Verbraucher unter gesundheitlichen Problemen. Im Allgemeinen ist der Mensch den Schadstoffen über die Nahrungskette und durch zufällige Aufnahme ausgesetzt. Deshalb gilt: "Wenn wir uns um unsere Gesundheit sorgen, müssen wir uns auch um die Umwelt und die Stoffe, die wir verwenden, sorgen". …

    Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Plants are not perfectly selective only to essential nutrients. They have ability to accumulate considerable quantities of contaminants like heavy metals from the environment: soil, water or air. As the result, human being and animals uses such plants may accumulate significant quantities of contaminants in the various parts of their tissue systems. Because of the possible toxicity encountered from contaminants the consumers suffer by health problems. Generally human exposed to contaminant through food chain and incidental ingestion. Therefore, 'If we worry about our care we must worry about the environment and substance we use.'.…

    Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The wide utilization of herbicides in the crop management has created a challenging problem in terms of residual herbicides. The major problems experienced are the contamination of soil, surface water, and possibly ground water with their residues. Therefore, systematic studies are needed to evaluate the toxicity of several substituted triazines and triazoles as well as their metal complexes in order to understand the role of substituents and metal complexation in modifying the activities of herbicidal compounds containing N-heterocyclic systems. This book describes the basic chemistry of derivatization and metal complexation of selected herbicide systems that can be used as a means for modifying their activities. Accordingly, Atrazine (ATZ), Simazine (SMZ), and Amitrole (ATA) were derivatized into HAATZ, HSMZ, and NSATA respectively. Co(II), Ni(II) and Cu(II) complexes of NASTA were synthesized. All the synthesized compounds were characterized on the basis of analytical, magnetic susceptibility, conductance, IR, NMR, UV-VIS spectral studies. An octahedral geometry for Co(II)-NSATA complex and square planar geometry for Ni(II)-NSATA and Cu(II)-NSTA complexes are proposed.…
