| Abstract | Im Rahmen der vorliegenden Studie wurden von 57 Rehen und 58 Gemsen aus den Südtiroler Jagdrevieren Moos in Passeier und Schnals die Leber, die Nieren und die Muskulatur auf ihre Schwermetallbelastung (Pb, Cd, Hg) untersucht. Dabei wurden Parameter wie Geschlecht, Alter, Körpermasse, Gesundheitsstatus, Jahreszeit, Gebiet, Seehöhe und Exposition des Lebensraumes als mögliche Einflußfaktoren geprüft. Aufgrund der Eignung der Wildtiere als Bioindikatoren kann aus den ermittelten Schwermetallgehalten auf die Kontamination ihrer Lebensräume rückgeschlossen werden.Die Bleibelastung (Medianwerte in ppm) war beim Gamswild (Nieren: 0,143; Leber: 0,120; Muskulatur: 0,112) höher als beim Rehwild (Nieren: 0,100; Leber: 0,082; Muskulatur: 0,050). Bei den Böcken konnten in der Leber signifikant höhere Konzentrationen gemessen werden. Die höhere Cadmiumbelastung (Medianwerte in ppm) des Rehwildes (Nieren: 2,254; Leber: 0,207; Muskulatur: 0,005) gegenüber dem Gamswild (Nieren: 1,333; Leber: 0,120; Muskulatur: 0,006) wurde auf die unterschiedliche Äsungsselektion zurückgeführt. Eine Abhängigkeit vom Alter konnte bei beiden Tierarten nachgewiesen werden. Die Quecksilberbelastung (Medianwerte in ppm) war sehr gering und ließ sowohl beim Rehwild (Nieren: 0,026; Leber: 0,012; Muskulatur: 0,000) als auch beim Gamswild (Nieren: 0,016; Leber: 0,006; Muskulatur: 0,006) eine jahreszeitliche Abhängigkeit erkennen.Liver, kidney and diaphragm samples of 57 roe deer and 58 chamois collected during the hunting season 1995 were examined for their heavy metal (Pb, Cd, Hg) concentrations. The possible influence of the parameters — sex, age, body weight, condition of health, season, region, altitude, and habitat exposure — were tested. Due to the suitability of wildlife as biological indicators, the measured concentrations provide information on the environmental pollution of their habitats.Lead concentrations (median content: ppm) were higher in chamois (kidney: 0,143; liver: 0.120; diaphragm: 0.112) than in roe deer (kidney: 0.100; liver: 0.082; diaphragm: 0.050). The highest levels measured in diaphragm can be accounted for by a secondary contamination originating from the lethal projectile. Higher concentrations have been detected in the liver of male animals than female. The higher cadmium concentrations (median content: ppm) in roe deer (kidney: 1.333; liver: 0.120; diaphragm: 0.006) have been attributed to the different grazing habits. A highly significant age dependency of the Cd concentration could be observed for both species of animals. The median mercury content (ppm) in roe deer (kidney: 0.026; liver: 0.012; diaphragm: 0.000) and chamois (kidney: 0.016; liver: 0.006; diaphragm: 0.006) was low. An influence of the season was seen in both species.Dans le cadre de la présente étude, 57 chevreuils et 58 chamois, provenant des territoires de chasse de Moos-in-Passeier et Schnals (Sud-Tirol), ont été étudiés en ce qui concerne leur contamination en métaux lourds (Pb, Cd, Hg) au niveau du foie, des reins et des muscles. L'effet éventuel des paramètres tels que le sexe, l'âge, la masse corporelle, l'état de santé, la saison, le territoire d'origine, l'altitude et l'exposition ont été testés à cette occasion. Ces espèces d'animaux sauvages se prêtent comme bioindicateurs et, à ce titre, leurs teneurs en métaux lourds sont révélatrices de la contamination de leurs habitats.Avec 0,143 pour les reins, 0,120 pour le foie et 0,112 pour les muscles, la teneur en Plomb (médiane en ppm) chez le Chamois se situait au-delà de celle du Chevreuil (0,100 pour les reins, 0,082 pour le foie et 0,050 pour les muscles). Chez les mâles, les teneurs au niveau du foie étaient significativement plus élévées. La charge plus élevée en Cadmium (médiane en ppm) chez le Chevreuil (reins: 2,254; foie: 0,207; muscles: 0,005) par rapport au Chamois (reins: 1,333; foie: 0,120; muscles: 0,006) est attribuée à un régime alimentaire distinct. Une dépendance de l'âge n'a pu être mise en évidence chez ces deux espèces. La charge en Mercure (médiane en ppm) était très faible et laissait apparaître, quant à elle, une variation saisonnière, aussi bien chez le Chevreuil (reins: 0,026; foie: 0,012; muscles: 0,000) que chez le Chamois (reins: 0,016; foie: 0,006; muscles: 0,006). |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
