Geology and environmental significance of sediment distributions in an area of the submerged Niagarels but there arc anomalously high values in some deepwater modern muds..In the bottom sediment habitat of modern benthos, the distribution of chironomids seems to reflect silt content. Oligochaetes are least in areas of thin Recent mud or exposed glaciolacustrine clay. . and sculpins are most numer

The dominant attached filamentous algae of Georgian Bay, the North Channel and Eastern Lake Huron: er outfalls, river mouths and harbour areas (e.g., in µg g., Cr 29.0, Cu 46.4, Ni 34.0, Pb 55.0) is indicative of discrete source loadings, while elevated levels at remote sites in eastern Georgian Bay (e.g., in µg g., Cr 12.0–15.5, Cu 18.0, Ni 15.0–16.0, Pb 8.5–8.8) are suggestive of generalized lo
