| Abstract | Analysiert wurden die Fluorid- und Bleikonzentrationen in 32 Geweihen von Rehböcken(Capreolus capreolus), die zwischen 1961 und 1999 in zwei benachbarten Waldgebieten (Gesamtfläche etwa 600 Hektar) des nördlichen Sauerlandes erlegt worden waren. Höchste Fluorid-und Bleigehalte wurden mit 7451 mg F−/kg Asche und 58,1 mg Pb/kg Trockensubstanz in Geweihen aus den Jahren 1967 beziehungsweise 1964 gefunden. Niedrigste Schadstoffgehalte wiesen zwei Geweihe aus dem Jahr 1998 auf (427 mg F−/kg Asche beziehungsweise 0,7 mg Pb/kg Trockensubstanz). Im Untersuchungszeitraum nahmen die Fluorid- und Bleigehalte der Geweihe deutlich ab, was auf eine Verringerung der Schadstoffbelastung des Untersuchungsgebietes hinweist. Diese Entwicklung wird als Beleg für die Wirksamkeit der seit den 1970er-Jahren in Deutschland durchgeführten Maßnahmen zur Minderung von Schadstoffemissionen aus Industrie, Privat-Haushalten und Verkehr gewertet. Die Studie illustriert die Eignung von Rehgeweihen für ein Monitoring der Schadstoffexposition von Wildlebensräumen und damit für eine Rekonstruktion der Umweltgeschichte auf lokaler oder regionaler Ebene.We analyzed fluoride and lead concentrations in 32 antlers of roe bucks(Capreolus capreolus), taken between 1961 and 1999 in two adjacent forest areas (size of approximately 600 hectares) of the northern Sauerland. Highest fluoride (7451 mg F−/kg ash) and lead (58.1 mg Pb/kg dry wt) concentrations ons were found in two antlers collected in 1967 and 1964, respectively. Lowest values (427 mg F−/kg ash and 0.7 mg Pb/kg dry weight, respectively) were measured in antlers of two bucks shot in 1998. Antler fluoride and lead concentrations markedly declined over the study period, which is regarded as indicative of a decreasing fluoride and lead contamination of the study area. This tendency is considered a proof of the efficacy of various emission control measures established in Germany since the 1970s, aimed at reducing pollutant discharges from industry, domestic sources and traffic. The study highlights the suitability of using roe deer antlers for a monitoring of contaminant levels in wildlife habitats and, by this, for a reconstruction of environmental history on a local or a regional scale.Nous avons analysé les concentrations de Fluor et de Plomb dans 32 bois de chevreuils(Capreolus capreolus) récoltés entre 1961 et 1999 dans deux forêts contiguës, d'une superficie totale de 600 ha, situées au Nord du Sauerland. Les concentrations maximales en Fluor (7.451 mg F−/kg de cendres) et en Plomb (58.1 mg Pb/kg de poids sec) ont été trouvées dans deux bois récoltés respectivement en 1967 et 1964. Les valeurs les plus faibles (soit respectivement 427 mg F−/kg de cendres et 0.7 mg Pb/kg de poids sec) ont été mesurées sur deux bois de brocards tirés en 1998. Les concentrations en Fluor et en Plomb ont décliné de façon sensible au cours de la période d'étude, ce qui est révélateur d'une diminution de la contamination en Fluor et en Plomb du site d'étude. Cette évolution est considérée comme une preuve de l'efficacité des mesures prises en Allemagne depuis les années 70 en vue de réduire les émissions de polluants par l'industrie, par la consommation domestique et par la circulation routière. L'étude illustre le fait que les bois du Chevreuil constituent un indicateur approprié pour la surveillance du degré de pollution des habitats de la faune sauvage; ils permettent par ailleurs de faire l'historique de l'évolution de la qualité de l'environnement au niveau local ou régional. |

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.
