AbstractAs part of a detailed infill lake sediment survey in the Florence Lake area of Labrador, waters were collected from 131 sites for trace metal determination. The distribution of 15 elements in waters and accompanying lake sediments were compared. Results indicate a significant correlation between U, Ni, Ce, La, Sm Tb, Cu, and Mn in the two media. Zn, Cd, Pb, F, V, Fe, and Co do not appear to have a sympathetic relationship. Evaluation of the variance of the total data set as well as site and blind duplicate data suggests that the lack of correlation for some elements may be related to relatively high within-site variability, particularly for the water data. The correlation in the distribution of sediment and water data suggests that the extensive National Geochemical Reconnaissance sediment database may be useful, in terms of environmental and public health concerns, for identifying areas in which naturally elevated concentrations of elements occur in surface waters.
