Abstract. Chemical data (pH, SO 4, Ca, Mg) from Québec lakes sampled between andand 2-yr (–) precipitation weighted mean sulphate concentrations from REPQ (Réseau d’échantillonnage des précipitations du Québec/Québec Precipitation Sampling Network) were examined to obtain relationships between precipitation sulphate, precipitation sulphate, precipitation Cited by: The acidity of fresh water is naturally variable, but most lakes and rivers have a pH within the range of 6 to 9.

Although any pH less than 7 can technically be considered acid, the terms ‘acidic’ and ‘acidified’ are usually reserved for freshwater systems which have an alkalinity of less than zero, and such systems usually have a pH of less than 5.

Spring-time acid pulses occur in Atlantic Canada, though these have been reduced in severity with decreases in winter acid deposition, while autumnal low pH pulses caused by organic acids are a regular occurence in Nova Scotia and must be separated from mineral acidity by:   An illustration of an open book.

Publication date   Regression kriging was used to map critical loads of acidity for ∼90, lakes in northern Saskatchewan. • A region greater t km 2 was predicted to be very sensitive to acidic deposition.

Predicted critical loads are low, with lakes lakes lakes are in exceedance of their critical loads under Cited by: Among the 64 lakes studied as part of the Noranda Project, the most acidic lakes () are located less than km from Rouyn-Noranda. Their acidity comes mostly from deposition of acidifying substances received in the last century, even though the acidity of several of these lakes was in some way affected by a natural component related to.

DesGranges and Hunter () observed the feeding behavior of 49 semicaptive, imprinted ducklings on seven lakes in Quebec and Maine that varied in acidity and productivity. They also observed that food availability was the key influence on duckling productivity, irrespective of acidity.

Lakes in the Atlantic provinces, Quebec and Ontario affected only by long-range sources show a general decline in sulfate (SO42−) concentrations, but with a relatively smaller compensating increase in pH or alkalinity.

The lakes of Earth are slowly disappearing, including the largest natural lake in Utah, the Great Salt Lake. Lakes provide a regional base level for the flow of freshwater, that captures meteoric water.
