Trace metals and benthic invertebrates in sediments of nearshore Lake Ontario at Hamilton Harbour / D.J. Poulton ... [et al.].: En13-5/86-196E-PDF
"This article is the result of work done in collaboration with Water Resources Branch, OME, on samples collected by NHRI in 1983. The objective was to assess the impact of discharges of metallic contaminants and PAH's from Hamilton Harbour on nearshore sediments and the benthic invertebrate community as a component of concurrent work by ONE for their report on Technical Summary and Management Options for Hamilton Harbour. The results show that operationally-defined geochemical phases are important in determining the distributions of metals and benthic macroinvertebrates in the study area. The distribution diagrams show that portions of the metals exported from the Harbour via the Ship Canal are deposited in the nearshore zone in plumes which are oriented either directly offshore from the Canal, or more or less parallel to shore in either direction.The benthic invertebrate distributions were mainly influenced by depth. However, within the appropriate depth ranges, most taxa showed consistently positive or negative correlations with concentrations of most metals. The strongest correlations were found most frequently with metals bound to organic matter"--Management perspective.
