Lake sediments are considered as an archive of physical,
chemical and biological conditions in lakes and their drainage basin. Under
relative steady sedimentation process and in the absence of bio-turbation,
depositional sequence of lake sediments provide a temporal composition pattern,
therefore the onset, rate and variations in present and past environmental
conditions could be assessed. In this sense, environmental impacts caused by
human activities, mainly those related to the release of persistent pollutants,
can be identified by appropriate analyses of sediment archives.
Lake Blidinje with area of some 2.5 km2 (on average) is the
biggest mountain lake in Bosnia and Herzegovina. It is located at an altitude
of 1185 m (N 43o36`; EO 17o29`), between Čvrsnica and Vran mountains. The lake
is very shallow with an average depth of about 0.5 m, and under the strong
influence of meteorological conditions. The lake has variable volume and
surface area. Lake Blidinje is an integral part of the Nature Park “Blidinje”
founded in 1995. Nature Park “Blidinje” (364 km2) includes the Čvrsnica massif
(2228 m), the Vran Mt. (2074 m), the valley Dugo polje and the western part of
the mountain ridge Čabulja named Debelo brdo, (1500 m).
Geologicalbase is very heterogeneous, made up of limestone from upper and middle Triassic,
and has a young Jurassic limestone, werfenian layers of red sandstone, sandy
shale, limestone plate marl, porous limestone and dolomite. On the surface most
of the Nature Park “Blidinje” lithosphere breaks through the ground and form a
single larger or smaller blocks to the tops form a rocky massif.
