1. A region in soil, sediment, or water where oxidation reactions occur, typically involving the breakdown of organic matter and minerals in the presence of oxygen
The oxidative zone near the surface of the soil supports aerobic microbial activity.
A zona oxidativa perto da superfície do solo suporta atividade microbiana aeróbia.
2. In hydrogeology, the upper layer of an aquifer or groundwater system where dissolved oxygen is present
Contaminants in the oxidative zone are more readily degraded by aerobic bacteria.
Os contaminantes na zona oxidativa são degradados mais facilmente por bactérias aeróbias.
3. In mining and ore processing, the weathered upper portion of an ore deposit where sulfides have been oxidized
The oxidative zone of the mineral deposit contains secondary enrichment.
A zona oxidativa do depósito mineral contém enriquecimento secundário.
