“…Secondly, it is influenced by external strontium sources from the environment, such as bathing water, aerosols and dust [20]. Strontium is found particularly in the internal portion of hair, such as the cortex and medulla but also in the external structures, such as the cuticle, where metals, such as calcium, adhere to the assumption that the chemical similarity between strontium and calcium is the cause [21].…”

“…As a tissue which exists externally, hair is influenced by strontium from two sources firstly, an internal source, the 87 Sr/ 86 Sr in blood where trace metal exchange occurs until subcutaneous formation prior to exposure from the scalp [19]. Secondly, it is influenced by external strontium sources from the environment, such as bathing water, aerosols and dust [20]. Strontium is found particularly in the internal portion of hair, such as the cortex and medulla but also in the external structures, such as the cuticle, where metals, such as calcium, adhere to the assumption that the chemical similarity between strontium and calcium is the cause [21].…”

Within post‐conflict communities, attempts to identify and repatriate unidentified and missing individuals poses a difficult task. As current forensic strategies commonly lack the capacity to provide region of origin assessments, forensic anthropologists/investigators are often unable to identify sources of DNA for kinship analysis. Using Thermal Ionization Mass Spectrometry (TIMS), hair samples from 10 volunteers were used to assess the variation in strontium isotope ratios (87Sr/86Sr) between extant people in Guatemala City and Coban; with a leach (external) and digest (dietary) signal analyzed for each sample. A two‐way anova demonstrated that the difference between 87Sr/86Sr of Guatemala City and Coban was statistically significant (F [1, 16] = 259.839, p < 0.05), with no statistically significant differences observed between leach and digest 87Sr/86Sr (F [1,16] = 4.319, p = 0.054). Overall, individuals from Coban demonstrate 87Sr/86Sr comparable to previously recorded baseline values, demonstrating a minimal change in diet which is reflected in associated surveys. Volunteers from Guatemala City, however, show a marked shift in 87Sr/86Sr away from predicted values highlighting the potential influence of imported goods. The results here highlight the applicability of 87Sr/86Sr in hair to serve as a potential tool to support the identification of unknown individuals in Guatemala in a forensic context.

“…In the past 5 years, isotopic and trace element analysis methods have been widely used in South Korea to estimate the geographical origin of human‐derived materials and identify individuals. These studies primarily utilized oxygen and Sr isotopic compositions and element concentrations, and these data have been applied to further investigate the reflection of dietary habits according to human habitation, environment, and geology 12,20 …”

“…These studies primarily utilized oxygen and Sr isotopic compositions and element concentrations, and these data have been applied to further investigate the reflection of dietary habits according to human habitation, environment, and geology. 12,20 In this study, δ 18 O and 87 Sr/ 86 Sr ratios were used along with major elements (Ca, Mg, Na, and K) and trace elements (Sr, Li, B, Al, Si, P, V, Fe, Zn, As, Rb, Mo, Ba, U, Be, TI, Mn, Ge, Se, Cs, W, and Hg) data to analyze and examine the characteristics of geographical origin of various brands of bottled water currently sold in South Korea. After the different brands of bottled water were classified into groups reflecting their hydraulic and geological characteristics, statistical techniques were applied to investigate different product-specific characteristics (intake source and manufacturer).…”

The production of bottled water requires a forensic discriminant technique that enables the identification of the brands or accidents caused by intended contaminants. The bottled water poisoning crimes have drawn much attention, and such crimes may recur in the future. The water is colorless and odorless, and thus it is difficult to detect contaminated water through visual observation. Thus, bottled water can be easily exploited for poisoning, and a method for tracing their origin is currently required.Methods: In this study, a total of 27 brands of bottled water samples were analyzed to determine stable oxygen isotopes, strontium isotopes, major and trace elements. The geographical origin of the water was traced based on the climatic and geographical characteristics of the location from where water was sourced, which was assumed to be reflected in the bottled water. Furthermore, we investigated whether this method can be applied to identify bottled water products. Results:The results demonstrated that the characteristics of the bottled water, including the oxygen stable isotope ratios, reflect the latitude and altitude of bottled water source in South Korea, from the high-latitude region to the coastal regions. In addition, the results indicated that excellent discrimination was achieved using strontium isotopes to identify source areas with different types of bedrock, complex underlying lithologies, and ocean areas in South Korea. A statistical method based on discriminant analysis was applied to measure trace elements, and the results effectively reflected the characteristics of water-rock interactions (cross-validated classification probability: ≥92%).Conclusions: These data suggest that the geographical characteristics of the source area are well reflected in commercial bottled water in South Korea. The proposed analytical methods can be utilized to trace the geographical origin of different bottled water samples and identify bottled water products used in poisoning crimes.
