“…Pigments are also useful for revealing successional changes in postglacial ecology and limnology, especially changes in aquatic postglacial productivity and phytoplankton diversity. They can provide information on the balance between allochthonous and autochthonous organic contributions to the sediments, postglacial water-level changes, past periods of meromixis, and the invasion of peatlands into the drainage basin (Fogg and Belcher, 1961;Belcher and Fogg, 1964;Czeczuga, 1965;Czeczuga and Czerpak, 1968;Wetzel, 1970;Gorham and Sanger, 1972;Sanger and Gorham, 1972;Whitehead and others, 1973;Handa, 1975;Brown and others, 1977;Sanger and Crowl, 1979;Culver and others, 1981).…”

Fossil pigments were examined in a 22 m core of varved sediment from the deep basin of Elk Lake, Minnesota. The lake appears to have evolved gradually from oligotrophic mesotrophic conditions in the earliest period (ca. 10,000+ years ago), to mesotrophic eutrophic conditions at present. Variations in productivity, species diversity, and relative importance of individual plant groups are related to changing climate and water level. The cyanobacteria gradually became more important in the planktonic flora; the least biomass and greatest variation occurred during the first 1000 years of the lake's postglacial history, and again during the mid-Holocene prairie interval. The ratio of chlorophyll derivatives to carotenoids indicates that there were no periods of large-scale influx of allochthonous detritus, nor were there major slumps of littoral detritus into the deep profundal zone. In addition, there is no evidence to indicate that excessive drying of the lake occurred during the mid-Holocene prairie interval.

Summary:The object of the investigation was the strongly polluted Dlugie Lake, Poland. Due to the development of the city of Olsztyn, for many years untreated municipal wastes were discharged into the lake. I n the core of bottom sediments the occurrence of bacteriochlorophyll a pheophytin ( Fig. 1) and Chlorobium chlorophylls and their degradation products ( Fig. 2 and 3) were observed, which suggested the presence of photosynthetic bacteria from the family Chlorobiaceae COPELAND. The development of the Chlorobiaceae population was caused by the increase of organic pollution as an effect of the urbanization process of the city of Olsztyn. It was shown that Chlorobium chlorophylls can be used as indicators of organic pollution in paleolimnological investigation.
