Abstract Lajes Field is an Atlantic Portuguese military air base that has been used by the USA since Cold War, primarily for intercontinental refueling. For this purpose, large fuel tanks and extensive pipeline network were constructed within municipality of Praia da Vitória, on Terceira Island, Azores. Over past two decades, leaks detected confirmed to have contaminated soils aquifers supply water public use. latter, identified contaminants include TPH, PAH, BTEX, VOCs, metals. Although risk assessment reports unacceptable risks human health, journalistic investigations suggest unusually high cancer rates, no possible exposure conducted date. To address gap, metals, serving as a proxy overall contamination exposure, measured using portable X-ray fluorescence (pXRF) in First Identified Skeletal Collection Azores (CEI/Açores). A total 64 skeletons with known places last residence selected (44 from Angra do Heroísmo, where present, 20 present). No significant differences mean ages at death observed between groups, sex distribution was similar. Additionally, soil samples 46 graves analyzed assess potential diagenesis. Greater concentrations Sb, As, Cd, Cr, Au, Mo, Sr, Sn, U, Zr found individuals Vitória ( p < 0.05). Soil measurements, Pearson’s correlation test, principal component analysis As levels can be partially attributed remaining likely result other factors, including particularly Mo. pioneering study contributes ongoing discussion subject, further research should both CEI/Açores living population discuss issue.
