The effect of dissolved humic substances (DHS), derived from drained raised bogs, on Sphagnum denticulatum Brid. and Myriophyllum spicatum L. habitats was studied in 13 lakes in the Pomeranian Lakeland (NW Poland). The sites selected for study included D. denticulatum habitats in softwater oligo-, meso- and polyhumic lakes and M. spicatum habitats in hardwater oligo- and mesohumic lakes. Taken into account were the sediment, water in the sediment, and the water layer immediately above the sediment within the population areas of both submerged-plant species. Samples of sediment and water in the sediment were taken from the plant root system in the near-shore, central and deepest zones of the population areas. As a result of the introduction of humic substances into lakes, their water became yellow to darkbrown, light intensity decreased and population areas were shifted towards the shore. With the rising concentration of humic substances the near-sediment water of S. denticulatum habitats was gradually losing its acidity and becoming richer ininorganic (mineral) nutrients. The ratio of humic acids to fulvic acids in the sediments changed noticeably. The proportion of fulvic acids in the humic substances (HS) concentration gradient in the sediment gradually increased. In M. spicatum habitats, where the HS concentration was increasingly high, the near-sediment water also became richer and richer in mineral nutrients, but its pH remained unchanged.
