The exposition to such contaminants can create environmental and health issues. The characterization of a former firing range in Athens, Greece will allow its monitoring and encourage its remediation. This study is focused on Pb contamination in the site due to its presence in ammunition. A dense sampling design with 91 location (10 m apart) was used to determine the spatial distribution of the element in the surface soil of the study area. Duplicates samples were also collected one meter apart from 8 random locations to estimate the heterogeneity of the site. Elemental concentrations were measured using a portable XRF device after simple sample homogenization in the field. Robust Analysis of Variance showed that the contributions to the total variance were 11% from sampling, 1% analytical, and 88% geochemical; reflecting the suitability of the technique. Moreover, the extended random uncertainty relative to the mean concentration was 91.5%; confirming the high heterogeneity of the site. Statistical analysis defined a very high contamination in the area yielding to suggest the need for more in-depth analysis of other contaminants and possible health risks. © Published under licence by IOP Publishing Ltd.info:eu-repo/semantics/openAccesshttp://creativecommons.org/licenses/by-nc-nd/4.0ContaminationEnvironmental engineeringEnvironmental technologyHealth risksLeadAthens , GreeceElemental concentrationsHigh heterogeneityIn-depth analysisLead determinationMean concentrationsPb contaminationRandom uncertaintiesRisk assessment7 INGENIERÍA Y TECNOLOGÍAConferencia781
