Abstract

Fundao mining tailings dam in Mariana District has collapsed in 2015 and caused the biggest environmental disaster in Brazil. Barra Longa District had its urban area invaded by toxic sludge and its population was extensively exposed to it. Blood and urine samples were collected from 11 residents, focused on investigating the presence of metals at the end of an exploratory health study in 507 inhabitants in 2016. Results have shown increased levels of aluminum, arsenic, cadmium, cooper, lead, manganese and nickel, and zinc defficiency in their body, as well as clinical outcomes. (AU)
