| Abstract: | The geochemistry of fluvial deposits is one of the most used proxies for contamination
assessment in mined areas. A river sediment survey was carried out in Iron Quadrangle
(IQ), Brazil, between 2013 and 2015. Subsequently, in the last four years, two dam
failures happened, causing great environmental damage. Geostatistical modelling was
used to model Potentially Toxic Elements’ spatial patterns and the definition of hot/
cold clusters for Arsenic contamination risk concerning catastrophic scenarios, such as
dam failure. and so used as a tool for vulnerability and risk assessment. The preliminary
results for Arsenic spatial distribution are introduced and discussed. |
