    “…In the Republic of Georgia, a 2018 national survey estimated that more than 40% of children aged 2–7 years had a blood lead concentration (BLC) of more than 5 µg/dL. The objective of this study was to document the feasibility of employing lead isotope ratios (LIRs) to identify and rank the Pb (lead) exposure sources most relevant to children across Georgia. …”
