Till geochemistry and sensitivity to acidification of lakes in northern Finland / A.-M. Kähkönen.

Title: Till geochemistry and sensitivity to acidification of lakes in northern Finland / A.-M. Kähkönen.
Author(s): Kähkönen, A. -M.
Date: 1992.
Publisher: Rovaniemi: Arctic Centre, University of Lapland
In: Symposium on the State of the Environment and Environmental Monitoring in Northern Fennoscandia and the Kola Peninsula, October 6-8, 1992, Rovaniemi, Finland - Extended abstracts. (1992.),
Abstract: Acidic or acidifying lakes are found in large areas of northern Finland. Acidity depends on atmosphere, organic activity in catchment and catchment sensitivity. Till is main local overburden, so its properties are paramount. 1008 lake water samples analysed in 1987-91, 30 000 till samples analysed for geochemistry of catchment. Ratio of amount of potential soluble aluminium of till to equivalent sum of base cations is plotted for four levels of alkalinity in both clear and humic lakes.
