(2021-12)
Non-metal, metal and metalloid oxyanions occur naturally
in minerals and rocks of the Earth’s crust and
are mostly found in low concentrations or confined
in specific regions of the planet. However, anthropogenic
activities ...
Pristine but metal-rich Río Sucio (Dirty River) is dominated by Gallionella and other iron-sulfur oxidizing microbes
(2017-03)
Whether the extreme conditions of acidity and heavy metal pollution of streams and rivers originating in pyritic formations are caused primarily by mining activities or by natural activities of metal-oxidizing microbes ...
