摘要

摘要氧的稳定同位素分析在人类学中被用于确定个体起源、追踪迁徙路线或人类社区迁移动力学等目的。氧同位素分析的相关方法是基于被分析个体骨组织磷酸基团内的氧同位素组成（δ18Op）与这些个体消耗的水（δ18Ow）之间的关系。在包括人类在内的许多哺乳动物物种中都观察到了这种关系。然而，烹饪实践对个体磷灰石磷酸盐同位素δ值的影响尚未得到研究。本研究使用实验室大鼠进行，研究了这些大鼠饮用水的热处理对骨磷灰石同位素组成（δ18Op）的影响。煮沸过程中，水的同位素组成值增加了约6.1‰，导致饮用水的大鼠的氧同位素值δ18Op增加了约4‰（29%）。可以预期，人类经常食用高同位素饮料和食物可能会导致个体的δ18Op超过同位素环境变异范围，甚至每千分之几。

Oxygen isotopic fractionation in rat bones as a result of consuming thermally processed water – bioarchaeological applications

Abstract Stable isotope analyses of oxygen are used in anthropology for such purposes as determination of origin of individuals, tracking migration routes or dynamics of human community relocation. The methodology related to oxygen isotope analysis has been founded on the relationship between its isotopic composition within phosphate groups of bone tissue (δ18Op) in individuals being analysed and the water consumed by such individuals (δ18Ow). Such a relationship has been observed in many species of mammals, including humans. However, the influence of culinary practices on the isotopic delta values of apatite phosphates of individuals has not yet been researched. The present study, which was conducted using laboratory rats, is an investigation of the influence of the thermal processing of water drank by such rats on the isotopic composition (δ18Op) of bone apatite. Increasing the value of the isotopic composition of water by about 6.1 ‰ during boiling resulted in an increase in the oxygen isotopic value δ18Op of rats drinking the water by about 4 ‰ (29%). It can be expected that regular consumption of heavily isotopic drinks and foods by humans may cause the δ18Op of individuals to exceed the range of isotopic environmental variability, even by a few per mille.

期刊介绍： Geochronometria is aimed at integrating scientists developing different methods of absolute chronology and using them in different fields of earth and other natural sciences and archaeology. The methods in use are e.g. radiocarbon, stable isotopes, isotopes of natural decay series, optically stimulated luminescence, thermoluminescence, EPR/ESR, dendrochronology, varve chronology. The journal publishes papers that are devoted to developing the dating methods as well as studies concentrating on their applications in geology, palaeoclimatology, palaeobiology, palaeohydrology, geocgraphy and archaeology etc.
