Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The accumulation of heavy metals in soils especially in mining environments is of increasing concern to researchers in the Agricultural industry. Consumption of vegetables and fruits containing heavy metals is one of the main ways in which these elements enter the human body. The present study investigated the concentration of heavy metals: Cu, Zn, Cr, As and Pb in soil as well as fruit samples collected from the rehabilitated sites in the Sierra Rutile environs to evaluate the possible health risks to human body through food chain transfer. The sampled plants showed high translocation factor values (TF1) implying that they could be labelled as accumulators of pollution. It can be concluded that the crops/plants grown in the rehabilitated lands in the Sierra Rutile environs absorb significant levels of some heavy metals from the polluted soil 72 pp. Englisch.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - L'accumulation de métaux lourds dans les sols, en particulier dans les environnements miniers, préoccupe de plus en plus les chercheurs du secteur agricole. La consommation de légumes et de fruits contenant des métaux lourds est l'un des principaux moyens par lesquels ces éléments pénètrent dans l'organisme humain. La présente étude a examiné la concentration de métaux lourds (Cu, Zn, Cr, As et Pb) dans le sol ainsi que dans des échantillons de fruits prélevés sur des sites réhabilités dans les environs de Sierra Rutile afin d'évaluer les risques potentiels pour la santé humaine par le biais de la chaîne alimentaire. Les plantes échantillonnées ont présenté des valeurs élevées du facteur de translocation (TF > 1), ce qui signifie qu'elles pourraient être qualifiées d'accumulatrices de pollution. On peut en conclure que les cultures/plantes cultivées sur les terres réhabilitées dans les environs de Sierra Rutile absorbent des niveaux importants de certains métaux lourds présents dans le sol pollué.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Die Anreicherung von Schwermetallen im Boden, insbesondere in Bergbaugebieten, gibt Forschern in der Agrarindustrie zunehmend Anlass zur Sorge. Der Verzehr von Gemüse und Obst, das Schwermetalle enthält, ist einer der Hauptwege, über den diese Elemente in den menschlichen Körper gelangen. In der vorliegenden Studie wurde die Konzentration der Schwermetalle Cu, Zn, Cr, As und Pb in Boden- und Obstproben untersucht, die an sanierten Standorten in der Umgebung von Sierra Rutile entnommen wurden, um mögliche Gesundheitsrisiken für den menschlichen Körper durch die Übertragung über die Nahrungskette zu bewerten. Die untersuchten Pflanzen wiesen hohe Translokationsfaktoren (TF>1) auf, was darauf hindeutet, dass sie als Akkumulatoren von Schadstoffen bezeichnet werden können. Daraus lässt sich schließen, dass die auf den sanierten Flächen in der Umgebung von Sierra Rutile angebauten Nutzpflanzen/Pflanzen erhebliche Mengen einiger Schwermetalle aus dem verschmutzten Boden aufnehmen. …

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - L'accumulo di metalli pesanti nel suolo, specialmente in ambienti minerari, è fonte di crescente preoccupazione per i ricercatori del settore agricolo. Il consumo di frutta e verdura contenenti metalli pesanti è uno dei principali modi in cui questi elementi entrano nel corpo umano. Il presente studio ha esaminato la concentrazione di metalli pesanti (Cu, Zn, Cr, As e Pb) nel suolo e in campioni di frutta raccolti dai siti bonificati nei dintorni della Sierra Rutile, al fine di valutare i possibili rischi per la salute umana attraverso il trasferimento nella catena alimentare. Le piante campionate hanno mostrato valori elevati del fattore di traslocazione (TF>1), il che implica che potrebbero essere etichettate come accumulatori di inquinamento. Si può concludere che le colture/piante coltivate nei terreni bonificati nei dintorni della Sierra Rutile assorbono livelli significativi di alcuni metalli pesanti dal suolo inquinato.…

Spo¿ywanie warzyw i owoców zawieraj¿cych metale ci¿¿kie jest jednym z g¿ównych sposobów, w jaki pierwiastki te dostaj¿ si¿ do organizmu cz¿owieka. W niniejszym badaniu zbadano st¿¿enie metali ci¿¿kich: Cu, Zn, Cr, As i Pb w glebie oraz próbkach owoców pobranych z terenów rekultywowanych w okolicy Sierra Rutile w celu oceny potencjalnego zagro¿enia dla zdrowia ludzkiego poprzez przenoszenie si¿ tych pierwiastków w ¿äcuchu pokarmowym. Próbki ro¿lin wykazäy wysokie warto¿ci wspó¿czynnika translokacji (TF>1), co oznacza, ¿e mo¿na je uznä za akumulatory zanieczyszcze¿.
