How brown waters are influenced by acidification: The HUMEX lake case study
AbstractIn order to assess how brown waters will react with changes in acid inputs caused by acid precipitation, it is important to estimate quantitatively the concentration of organic anions in solution. A new method of determining the organic anion component of brown waters was developed. The approach was then tested on water samples collected in Nova Scotia. The method shows that, with a knowledge of pH, acid neutralization capacity (ANC), and dissolved inorganic carbon (DIC), a titration curve which estimates the change in organic anion concentration and its relationship to changes in ANC can be produced. This method was applied to the waters of Sjervatjern. Preliminary results based on estimated data suggest that because of the already low pH values of the Norwegian lake water, organic acids will not offer much neutralization capacity to inputs of mineral acids.
