ABSTRACT Soils of the Quadrilátero Ferrífero are rich in mineral resources, especially gold and iron. Soil management and mining activities greatly impact soil biology. However, studies addressed to the diversity of microorganisms and their ecological role in the recovery of these areas are scarce. This study aimed to assess the yeast occurrence in soils with natural vegetation (Atlantic Forest, neotropical savanna, and iron outcrop) and areas with anthropogenic modifications (Eucalyptus stand and rehabilitated area) in the Quadrilátero Ferrífero region. We […]

As atividades relacionadas com mineração e indústria metalúrgica são responsáveis pela poluição de extensas áreas de solo em todo o mundo, sendo seus efeitos ainda pouco conhecidos nas condições brasileiras. No presente trabalho, os teores totais e solúveis em água de metais pesados, a densidade e a atividade microbiana foram avaliados em 1996, em sete locais de uma área de deposição de rejeitos da industrialização de zinco, em elevado estádio de degradação, e num local fora da área contaminada, considerado […]
