Lake sediments can be significantly impacted by industrial activities. These impacts vary among sites and include both local point sources and atmospherically-derived pollution. Here we present results of a lake sediment pollution record from Ullswater, UK, where lead mining activities have taken place within the catchment since 1690, although large-scale mining did not begin until 1840. Metal concentration...
Sediment chemistry and arcellacean community composition were analyzed to study the ecological effects of copper mine-derived acidic and metal-rich waters in a freshwater bay in eastern Finland. To track spatial and temporal changes in the bay, 32 mine-impacted (top) and pre-impact (bottom) samples were analyzed from 16 short sediment cores taken along a transect extending from the pollution source...
