PALEOLIMNOLOGICAL RECORDS OF CAROTENOIDS AND CARBONACEOUS PARTICLES IN SEDIMENTS OF SOME LAKES IN SOUTHERN ALPS

Stratigraphic analyses of organic carbon, organic nitrogen and algal and bacterial carotenoids in short cores of profundal sediments of four alpine lakes (Tovel, Leit, Paione superiore and Tom) were used to reconstruct their trophic history. In addition, depth distribution of carbonaceous particle concentrations provided information on lake contamination from atmospheric deposition.
