“…Over four decades ago, Nixon and Helsby (1976) showed a relationship between strontium concentrations of tap water in 12 English towns and tooth enamel of their human residents. However, a more recent study found no relationship with modern tooth enamel 87 Sr/ 86 Sr and tap water 87 Sr/ 86 Sr throughout the Netherlands (Kootker et al, 2020). In another study, Tipple et al (2018) found that modern human hair 87 Sr/ 86 Sr reflected tap water 87 Sr/ 86 Sr.…”

The analysis of 87 Sr/ 86 Sr has become a robust tool for identifying non-local individuals at archeological sites. The 87 Sr/ 86 Sr in human bioapatite reflects the geological signature of food and water consumed during tissue development. Modeling relationships between 87 Sr/ 86 Sr in human environments, food webs, and archeological human tissues is critical for moving from identifying non-locals to determining their likely provenience. In the Andes, obstacles to sample geolocation include overlapping 87 Sr/ 86 Sr of distant geographies and a poor understanding of mixed strontium sources in food and drink. Here, water is investigated as a proxy for bioavailable strontium in archeological human skeletal and dental tissues. This study develops a water 87 Sr/ 86 Sr isoscape from 262 samples (220 new and 42 published samples), testing the model with published archeological human skeletal 87 Sr/ 86 Sr trimmed of probable non-locals. Water 87 Sr/ 86 Sr and prediction error between the predicted and measured 87 Sr/ 86 Sr for the archeological test set are compared by elevation, underlying geology, and watershed size. Across the Peruvian Andes, water 87 Sr/ 86 Sr ranges from 0.7049 to 0.7227 (M = 0.7081, SD = 0.0027). Water 87 Sr/ 86 Sr is higher in the highlands, in areas overlying older bedrock, and in larger watersheds, characteristics which are geographically correlated. Spatial outliers identified are from canals, wells, and one stream, suggesting those sources could show non-representative 87 Sr/ 86 Sr. The best-fit water 87 Sr/ 86 Sr isoscape achieves prediction errors for archeological samples ranging from 0.0017-0.0031 (M = 0.0012, n = 493). The water isoscape explains only 7.0% of the variation in archeological skeletal 87 Sr/ 86 Sr (R 2 = 0.07), but 90.0% of archeological skeleton 87 Sr/ 86 Sr fall within the site isoscape prediction ± site prediction standard error. Due to lower sampling density and higher geological variability in the highlands, the water 87 Sr/ 86 Sr isoscape is more useful for ruling out geographic origins for lowland

“…Certain foods will be transported to the communities and therefore could, potentially, lead to more homogenous isotopic signatures recorded in human tissue. This effect has been demonstrated most recently by Kootker et al [31] examining the relationship of 87 Sr/ 86 Sr ratios in Dutch tap water and human tooth samples. While a direct comparison with the Netherlands is invalid due to the significant socio-economic differences between the countries, this study clearly establishes that regional geology has a major influence and hence it can be concluded that the supermarket diet does not significantly skew the data in Mexico.…”

“…Future study of Mexican bottled water could potentially indicate the proportion of Sr in human body tissues derived from bottled and tap water. Even though the low Sr content in drinking water means that the bulk of Sr ingested by humans is from food [31], it is a significant finding of this work that the 87 Sr/ 86 Sr ratios of human hair and tap water are strongly correlated.…”

“…Therefore, bedrock more susceptible to weathering will have a greater influence on the 87 Sr/ 86 Sr ratios of water than less soluble bedrocks [55]. Overall, ground water and therefore tap water is expected to reflect a wide range of Sr isotope ratios as it will reflect a mixture of recent rainwater and weathered bedrock [31]. This study is designed to assess how well drinking water reflects the bioavailable Sr taken up by hair of local individuals.…”

“…Due to the fact that the modern human's diet is becoming increasingly globalized, researchers have argued that isotopic signatures are becoming more and more homogenized [29,30] and may therefore inhibit scientists from distinguishing populations. This was most recently been demonstrated in the Netherlands, where there is no correlation between 87 Sr/ 86 Sr ratios in human enamel samples and tap water and that 87 Sr/ 86 Sr of water could not be used as a proxy in a mobility contexts [31]. For Mexico, over half of the food product imports originate from the United States [32].…”

Recovery and identification of heavily burnt and fragmented skeletal remains pose significant challenges in fire and arson investigations. The ability to identify individuals is crucial in such cases, prompting extensive research into various techniques to aid in the identification process, including isotopic analysis. Although direct personal identification is not achievable through isotopic analysis of skeletal remains, it serves as a valuable tool for obtaining chemical elements of the biological profile. Strontium (Sr), oxygen (O), and carbon (C) isotope analyses have been widely used in archeological contexts but are relatively new approaches in the medicolegal domain. Oxygen isotope analysis, for instance, offers insights into the burning temperature, while strontium isotope analysis provides valuable information for tracing the individual's movement across geologically distinct landscapes. Consequently, the investigation of the impact of heat on the biogenic isotope composition of human bones in forensic contexts has gained significant attention. This article presents a comprehensive overview of the key archeological and forensic questions addressed by Sr–O–C isotope analysis of burnt skeletal remains. By examining the current state of the art and prospects, we aim to contribute to a broader understanding and potential advancements in the field of forensic isotope research.This article is categorized under: Forensic Biology > Interpretation of Biological Evidence Forensic Anthropology > Trauma Analysis
