The discharge of acid mine drainage (AMD) from sulphur bearing mineral deposits causes iron to precipitate as hydroxides and the formation of ochreous deposits on the substrate of the receiving river system. The sediments ...

The impact of acid mine drainage (AMD) on lotic receiving waters is complex and difficult to assess. While low pH, elevated sulphate and metals all characterize AMD these vary both spatially and temporally, with high ...

Sampling acid mine drainage (AMD) impacted sediments is complex requiring appropriate field sampling techniques to ensure representative samples which are both repeatable and reproducible. This report examines the important ...

This review examine the action of acid mine drainage (AMD), which is a multifactor pollutant, on surface waters. It affects aquatic ecosystems via a number of direct and indirect pathways. Major impact areas are coastal ...

Water and suspended particulate matter (SPM) was collected at weekly intervals during low flow conditions from the Avoca River (May and August, 1994). The total concentration of Zn, Cu, Cd and Fe was measured in both the ...

As part of an extensive study of the environmental impacts of the abandoned CU-S mines at Avoca in County Wicklow in Ireland, extensive studies were made of the river sediments and their toxicity. Originally written in ...
