Chemical characteristics of lakes in the Truelove Lowlands, Devon Island, Northwest Territories / by Dennis J. Gregor and Wm. D. Gummer.: En37-221/1987E-PDF
"A unique opportunity was provided in 1985 to obtain characterization of the chemistry of surface waters of Truelove Lowlands, Devon Island, Northwest Territories. The ionic composition of seven lakes in the lowlands are described and discussed as regards their sensitivity to acidic deposition. A comparison of field and laboratory analyses is made drawing attention to possible inaccuracies in technology and/or the change in sample integrity over time. Metal residue concentrations in water, lake sediment and snow are presented and reference is made to efforts to collect and quantify organochlorine residues in freshwater shrimp (Lepidurus sp.). Sediment samples from the lakes are described with respect to metal concentrations and their toxicity to a mixed culture phytoplankton population"--Abstract.
