| 520 | 0 |a"Dissolved organic matter (DOM) is an important constituent in coloured waters from southwestern Nova Scotia. An improvement in our understanding of the distribution and chemical character of DOM in these waters is necessary if we are to learn how it affects water quality. Acidic fractions of DOM are responsible for the natural acidity of these waters, and the contribution of natural acids to the total acidity of these waters is a major concern ofthe LRTAP program. Complexation by DOM fractions is a possible mechanism for protecting local fish populations from the toxic effects of aluminum and other metals. To effectively address these concerns, the spatial and seasonal variations in the distribution of organic acids, their acid content, and acid strengths must be known. This preliminary report presents initial results from a continuing study. It shows that acidic fractions make up about half of the DOM at sites in Kejimkujik National Park, NS and in Barrington Township, NS. Variations in type of orqenic acid are found to occur when samples are grouped by location and season"--Management perspective, p. i. |
