Abstract

This report considers the distribution of selected trace metals in water, suspended matter and sediments of southern Lake Michigan and in surficial sediments of lower Green Bay. Accumulations of AS, Br, Cr, Cu, Hg, Pb and Zn in fine-grained surficial sediments of southern Lake Michigan, apparently determined by patterns of sediment deposition, correlate closely with sediment concentrations of organic carbon and iron. Organic carbon concentrations of surficial sediments are more highly correlated with concentrations of Cu, Pb and Zn in surficial sediments of lower Green Bay than are either Fe or Mn contents. Mean concentrations of trace metals in suspended matter near the sediment-water interface of southern Lake Michigan equal or exceed amounts in surficial sediments. Horizontal (geographic) and vertical distributions of concentrations of nine trace metals (Cd, Cr, Co, Cu, Fe, Pby Mn, Ni and Zn) in waters of southern Lake Michigan were examined during the period June - October, 1971 . Distributions of Cu, Fe, Pb and Zn in filtered lake water are presented. Metal concentrations are typically highest near areas of industrialization and major tributary enbouchment. Concentrations of Cu, Fe, Pb and Zn in nearshore areas of southern Lake Michigan are typically higher than concentrations in offshore waters, but this trend is inconsistent. Horizontal distributions of trace metals in the epilimnion appear to be primarily determined by current patterns. No consistent variations of concentration with depth were observed for the trace metals investigated.
