Chemical speciation is a relevant topic in environmental chemistry since the (eco)toxicity, bio (geo)chemical cycles, and mobility of a given element depend on its chemical forms (oxidation state, organic ligands, etc.). ...

On January 25, 2019, a tailings dam at the Corrego do Feijao iron ore mine (Brumadinho, Minas Gerais, southern Brazil) ruptured and released similar to 12 million m(3) of mine tailings into the Paraopeba River, which is ...

Resonant inelastic X-ray scattering, also named X-ray resonant Raman scattering, was recently used to discriminate local chemical environments. By means of this novel technique, the speciation of samples could be attained ...

This work presents the first comprehensive organic characterization of atmospheric aerosols from an agro-industrial region (São Paulo State, Brazil) highly impacted by biomass burning. The organic speciation was performed ...
