This data paper reports bioavailable strontium isotope ratios from soils and rocks across Israel and from sediment layers at seven archaeological sites. The authors frame the data as a baseline for tracing where people, animals and foods came from.
Key numbers
- A total of 60 soil samples and 48 rock samples were analyzed (p. 3643).
- Soil isotope ratios ranged from 0.70577 to 0.71020 (p. 3643).
- The paper notes that isotope ratios of bones and teeth reflect strontium from food and drink consumed while the tissue formed (Abstract).
Methods (brief)
Soils were leached with 1 M ammonium nitrate to obtain the bioavailable fraction; rocks were processed separately; strontium was purified and measured by multi-collector ICP-MS against NIST SRM 987.
Evidence fitness
Supports isotope-ratio baselines for provenance work, including food studies. It does not support exposure or toxicity statements.
Limitations
Isotope ratios only; soil leachates approximate, but do not equal, what plants take up.
