Abstract:
Lake and ground water in the catchment areas of Piaseczno
(mesotrophic), Łukie (eutrophic) and Moszne (dystrophic) lakes located in the
Polesie Region (South-Eastern Poland) were studied in 1996–1997. Ground water
were sampled from the wells installed on the lake shores (several metres from
the shoreline) and lake water from the littoral zone next to the wells. EC,
pH, concentration of Ca, Mg, K, Na, N-NH4, N-NO3, P-PO4
as well as DOC and its fractions were determined. Mineralisation of ground
water was higher and pH lower than that of the littoral lake water. The
amount of fulvic acids both in lake and ground water was higher than the
amount of humic acids. |
