Impat of Bleached Kraft Poulp Mill Effluent on the Nearshore Benthic Community of Jackfish Bay, lake Superior

摘要

We assessed the impact of bleached kraft pulp mill effluent on benthic inverte- brate community structure in the shallow (1 m) nearshore waters of Jackfish Bay, Lake Superior. Duplicate benthic samples were collected from 0.5 m~2 quadrats at twenty-three stations along two shorelines of Jackfish Bay up to 1800 m form the point of effluent discharge, and from a reference station located within the Jackfish Bay study area.
