520 |aThirty nine lakes from southwest Nova Scotia and 33 from all over Newfoundland were sampled semi-annually from the Spring of 1983. A number of acidification related water chemistry variables were evaluated for trends using non-parametric techniques. Results showed that pH increased in almost half of Newfoundland lakes. Acid neutralization capacity (ANC) increased in one third of Nova Scotia lakes and in six of the Newfoundland sites. Despite the strong evidence from pH and ANC which suggested a reduction in acidification effect, only a few lakes in Nova Scotia showed decreases in sulfate (SO42). Moreover, base cation concentrations also did not seem to vary much over time"--Abstract, page i.
