Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographic references. "To evaluate benthic conditions in the Spanish Harbour Area of Concern (AOC) and whether they are improving over time, benthic invertebrate community structure, sediment toxicity and sediment contaminant concentrations were assessed). Spatial difierences between conditions at contarninated and Great Lakes reference sediments as well as temporal differences between 2009 (current conditions) and 2003 (when a similar assessment was conducted) were examined for 7 sites. Benthic macroinvertebrate community composition and toxicological response of four benthic invertebrates in laboratory toxicity test sites were compared to biological criteria developed for the Laurentian Great Lakes using multivariate analysis. Based on the sediment decision-making framework, data from the multiple lines of evidence were integrated to arrive at an assessment outcome on a site per site basis"--Summary, p.i.
