Spark source mass spectroscopy was used to analyze 61 elements in ten ferromanganese nodules found near Glenora in the Bay of Quinte at the eastern end of Lake Ontario. Most minor elements, including As, Pb, and Hg, have concentrations between 1-100 µg/g. F, S, Co, Zn, and La have concentrations in 100 µg/g range. Ba and Sr are present at levels of 1% and 0.1% respectively. Compared to similar measurements on nodules found in the Great Lakes and in other parts of the globe, values reported here are generally lower. Compared to their marine equivalents, lake nodules appear to be inferior scavengers of minor elements. Examination of all available data corroborates the postulate that marine biological material is an important source of minor elements found in oceanic nodules.
