Probing sources of strontium exposure in pregnant individuals living near unconventional oil and gas wells using urinary 87Sr/86Sr isotope ratios
To our knowledge, this study is the first to explore the use of urinary <sup>87</sup>Sr/<sup>86</sup>Sr isotope ratios to investigate sources of Sr exposure. Results are consistent with the hypothesis that a predominant source contributes to Sr exposure in most exposed EXPERIVA participants, but the contribution of unconventional oil and gas wells around participants' residences remains unclear. Findings should be considered as exploratory given the many limitations of this study. Our effort will hopefully benefit future studies aimed at identifying the sources of exposure in human populations.
