| Sammendrag: | Cadmium (Cd) concentrations were measured in water and sediments from eight lakes in the
acid stressed area of western Telemark, Norway. The lakes were either not limed (group I, n
=2), limed once in 1992 (group II, n=4) , or regularly since 1982 (group III n=2). Cd
concentrations in the lake surface water were generally low as only one sample exceeded the
detection limit (0.05 mg/l). The Cd levels in the bottom water were higher and highest in the
unlimed lakes. The Cd concentrations in the sediments averaged 1.06, 1.79, and 2.52 mg/g in
group I, II , and III respectively, but with much variation within the groups. The Cd levels of
the sediment samples, which were collected from the deepest part of the lakes, increased with
the depth and with the Fe content in sediments. |
