The Acidification of Ontario lakes : an assessment of their sensitivity and current status with respect to biological damage

Abstract

This report describes the water chemistry of 6,000 lakes in Ontario. Trends in some water chemistry parameters are strongly correlated with acid deposition rate. Although this sample represents a small fraction of the estimated 262,000 lakes in Ontario, there are regions of the province where the lake sample is sufficiently large to allow estimates of the number of lakes at various stages of acidification to be made.
