Metal sulphates are one of the major contributors to acid mine drainage (AMD) or acid rock
drainage (ARD). AMD occurs by the oxidation of metal sulphides. Sulphides produce …

Streams affected by acid mine drainage (AMD) are highly stressed ecosystems and occur
worldwide. These streams typically have low pH, high concentrations of dissolved metals …

The oxidation of pyrite to release ferrous iron and sulfate ions to solution involves the
transfer of seven electrons from each sulfur atom in the mineral to an aqueous oxidant …

The metabolism of sulphur in angiosperms is reviewed under the aspect of exposure to
ecologically relevant concentrations of sulphur, heavy metals and metalloids. Because of the …

Intensive sampling of acid mine drainage from adits draining the abandoned copper and
sulphur mines at Avoca, south-east Ireland, has confirmed a seasonal variation in the Zn: Cu …

Abstract Effects of acid mine drainage (AMD) were investigated in surface waters
(Laranjinha River and Ribeirão das Pedras stream) and groundwaters from a coal mining …

Aim Little is known about factors affecting the elevational and longitudinal zonation of
tropical Andean stream communities. We investigated epilithon, macroinvertebrate and fish …

This paper documents the solid phases associated to acid mine drainage (AMD) at the
Tharsis mines (SW Spain). It provides an inventory of the AMD-precipitates, describing their …

A comparative study has been carried out between experimentally and naturally weathered
pyrites. Both were found to share similar species of weathering products and a similar …

Land-use practices can greatly impact water quality. Escherichia (E.) coli and Enterococcus
are accepted water quality indicators. However, surprisingly little research has been …
