Transformações no solo e concentração de mercúrio em uma sequência de latossolos de platô na bacia do Rio Negro (AM): dinâmica natural ou intervenção antrópica?

GeoTextos, 2021
Um dos problemas ambientais conhecidos na Amazônia é a alta concentração de mercúrio (Hg) em algumas classes de solos, corpos hídricos e peixes. Estes problemas foram, por diversas vezes, atribuídos à mineração do ouro.
