Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Globally, Heavy metals have been used by humans for thousands of years. The main threats to human health from heavy metals are associated with exposure to cadmium, lead, arsenic and mercury. People may be exposed to potentially harmful chemical, physical and biological agents in food, air, water and soil. In the present study, concentrations of heavy metals (Cadmium, Lead, Copper, Nickel and Zinc) were determined in Poultry Chicken (Gallus domesticus) from selected areas in the cities like Karachi, Hyderabad and Thatta all in the province of Sindh. All samples showed presence of Cadmium, Lead, Nickel, Zinc and Copper. The levels recorded in the samples were under the permissible limits recommended by the WHO, FAO and ANZFA, except that in the samples from Karachi, the levels of Ni and Pb exceeded the maximum permissible limits in liver, meat and blood. The present study indicated that heavy metal contaminants come from unhygienic poultry feed material. The research techniques and information are helpful for graduate and research students of Biological and Environmental Sciences. 112 pp. Englisch.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - À l'échelle mondiale, les métaux lourds sont utilisés par les humains depuis des milliers d'années. Les principales menaces pour la santé humaine liées aux métaux lourds sont associées à l'exposition au cadmium, au plomb, à l'arsenic et au mercure. Les personnes peuvent être exposées à des agents chimiques, physiques et biologiques potentiellement nocifs présents dans les aliments, l'air, l'eau et le sol. Dans la présente étude, les concentrations de métaux lourds (cadmium, plomb, cuivre, nickel et zinc) ont été déterminées chez des poulets domestiques (Gallus domesticus) provenant de zones sélectionnées dans des villes telles que Karachi, Hyderabad et Thatta, toutes situées dans la province du Sindh. Tous les échantillons ont révélé la présence de cadmium, de plomb, de nickel, de zinc et de cuivre. Les niveaux enregistrés dans les échantillons étaient inférieurs aux limites autorisées recommandées par l'OMS, la FAO et l'ANZFA, à l'exception des échantillons provenant de Karachi, où les niveaux de Ni et de Pb dépassaient les limites maximales autorisées dans le foie, la viande et le sang. La présente étude a indiqué que les contaminants lourds proviennent d'aliments pour volailles non hygiéniques. Les techniques de recherche et les informations sont utiles pour les étudiants diplômés et les chercheurs en sciences biologiques et environnementales. …

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Globalmente, os metais pesados têm sido utilizados pelos seres humanos há milhares de anos. As principais ameaças à saúde humana decorrentes dos metais pesados estão associadas à exposição ao cádmio, chumbo, arsénico e mercúrio. As pessoas podem ser expostas a agentes químicos, físicos e biológicos potencialmente nocivos nos alimentos, no ar, na água e no solo. No presente estudo, foram determinadas as concentrações de metais pesados (cádmio, chumbo, cobre, níquel e zinco) em galinhas domésticas (Gallus domesticus) de áreas selecionadas nas cidades de Karachi, Hyderabad e Thatta, todas na província de Sindh. Todas as amostras apresentaram presença de cádmio, chumbo, níquel, zinco e cobre. Os níveis registados nas amostras estavam abaixo dos limites permitidos recomendados pela OMS, FAO e ANZFA, exceto nas amostras de Karachi, onde os níveis de Ni e Pb excederam os limites máximos permitidos no fígado, carne e sangue. O presente estudo indicou que os contaminantes de metais pesados provêm de rações avícolas anti-higiénicas. As técnicas de investigação e as informações são úteis para estudantes de pós-graduação e investigação em Ciências Biológicas e Ambientais. …

G¿ówne zagro¿enia dla zdrowia ludzkiego zwi¿zane z metalami ci¿¿kimi wynikaj¿ z naräenia na kadm, o¿ów, arsen i rt¿¿. Ludzie mog¿ by¿ naräeni na dziäanie potencjalnie szkodliwych czynników chemicznych, fizycznych i biologicznych obecnych w ¿ywno¿ci, powietrzu, wodzie i glebie. W niniejszym badaniu okre¿lono st¿¿enia metali ci¿¿kich (kadmu, o¿owiu, miedzi, niklu i cynku) w drobiu (Gallus domesticus) pochodz¿cym z wybranych obszarów w miastach takich jak Karaczi, Haidarabad i Thatta, wszystkie po¿o¿one w prowincji Sindh. We wszystkich próbkach wykryto obecno¿¿ kadmu, o¿owiu, niklu, cynku i miedzi. Poziomy odnotowane w próbkach by¿y poni¿ej dopuszczalnych limitów zalecanych przez WHO, FAO i ANZFA, z wyj¿tkiem próbek z Karaczi, gdzie poziomy Ni i Pb przekroczy¿y maksymalne dopuszczalne limity w w¿trobie, mi¿sie i krwi. Niniejsze badanie wykazäo, ¿e zanieczyszczenia metalami ci¿¿kimi pochodz¿ z niehigienicznych materiäów paszowych dla drobiu. Techniki badawcze i informacje s¿ pomocne dla absolwentów i studentów kierunków biologicznych i ¿rodowiskowych. …
