本文汇编了NERC同位素地球科学实验室在过去15年中从人类牙釉质中提取的锶和氧同位素数据。这些多项而且往往是小规模的研究结合在一起，提供了来自英国的数据概述。锶的同位素组成在0.7078至0.7165之间(不包括被认为来自非英国的个人)。锶浓度的中位数为84ppm，但有一种与海水锶同位素组成有关的锶浓度增加的载体，这种增加主要见于来自苏格兰西海岸的个人，可归因于将海藻用作肥料。氧同位素数据服从正态分布，平均值为17.7‰+/-1.4‰(2SD n=615)。在降雨量较低的英国东部和降雨量较高的西部地区，为人类釉质值提供了控制组的两个本地个体亚群：17.2‰+/-1.3‰(2SD，n=83)和西部地区=18.2‰+/-1‰(2SD，n=40)。这些数据使得能够直接比较埋葬人口和对照数据集之间的人口平均值，以评估起源的共同性。
This paper presents a compilation of strontium and oxygen isotope data from human tooth enamel that has been produced at NERC Isotope Geosciences Laboratory over the last c. 15 years. These many and often small studies are here combined to provide an overview of data from Britain. The strontium isotope composition ranges between 0.7078 and 0.7165 (excluding individuals deemed to be of non-British origin). The median Sr concentration is 84 ppm but there is a vector of increasing Sr concentrations related to seawater strontium isotope composition that is seen in individuals predominantly from the west coast of Scotland attributed to the used of kelp as a fertilizer. The oxygen isotope data is normally distributed with a mean value of 17.7 parts per thousand +/- 1.4 parts per thousand (2SD n = 615). Two sub-populations of local individuals have been identified that provide control groups for human enamel values from the eastern side of Britain where there are lower rainfall levels: 17.2 parts per thousand +/- 1.3 parts per thousand, (2SD, n = 83) and western area of Britain where rainfall levels are higher = 18.2 parts per thousand +/- 1 parts per thousand, (2SD, n = 40). These data make it possible to make direct comparisons of population means between burial populations and the control dataset to assess commonality of origin.
