- Abstract
Bones can be a very good marker of environmental contamination by fluoride. Bones in a living organism have a different composition than in a dead one. As a result of adsorption from soil, bones from archeological excavations usually have more fluoride than those in a living body, and a significant portion of the fluorides they contain are acquired after death. This paper presents the results of a studies on fluoride content of sheep mandibles from archeological excavation sites in Szczecin. An attempt was undertaken to define how the chronological age of the bones and the time they had been lying in soil affected the bones. The material consisted of sheep mandibles from several excavations sites: Szczecin Mścię cino, Szczecin Rynek Warzywny, and Szczecin Zamek Ksićżć t Pomorskich (Szczecin Castle of Pomeranian Dukes). Cultural layers in these excavations were mostly formed from humus and humus with sand and clay. The fluoride content was determined by an ion-selective electrode with the pH/mV Orion 920A. Fluoride content was determined in 270 mandibles, which were classified into sheep age categories and according to the archeological age of the bones. The individual and archeological age of the sheep bones was determined by archeologists during the initial tests of the bones. A comparative evaluation of the significance of differences in the average fluoride content in the bones was performed by means of a single factor analysis of the orthogonal variance. The least significant differences were estimated by Tukey's test. The results show that the fluoride content depends on the individual age of animals and the chronological age of bones. The fluoride content of the sheep mandibles increased along with the individual age of the animals. Moreover, chronologically younger bones contained significantly less fluoride than older ones. In the sheep mandibles which lay longer in soil, the fluoride content tended to increase with the chronological age, while in chronologically youngest bones the tendency was reverse.
