Evaluation of the regional acidification of lakes in eastern Canada using ion ratios / by D.S. Jeffries. : En13-5/86-79E-PDF
"The ionic composition of lakewaters changes in response to acidic deposition. The alteration is usually manifested as decreased acid neutralizing capacity (ie alkalinity), and increased sulphate (and sometimes calcium + magnesium) concentrations. Given the predictable nature of these changes, it is possible to evaluate the geographic extent of the influence of acidic deposition by calculating appropriate ion ratios for lakes spread across eastern Canada. This report presents the results of such an evaluation in which ratios (alkalinity 3 ion : calcium + magnesium, sulphate = calcium + magnesium, and alkaninity : sulphate) were calculated for a large, high quality data base containing information for over 7000 lakes across all regions of eastern Canada. Contour maps illustrating the variability in the ratio values were prepared"--Executive summary, p. iii.
