Abstract

The water chemical and physical features (pH, conductivity, Na+, K+, Ca2+, Mg2+ concentration, water table) of fi ve mires (Nyírjes lake at Sirok, Kis-Mohos and Nagy-Mohos at Kelemér, Bábtava and Nyíres lake in the Bereg region) were investigated in North Hungary. Th e description of water chemical relations of these mires is new result. Th e pH of these mires was low, the means were between 3.29 and 5.92. Th e mean corrected conductivity ranged between 11.08 and 176.6 μScm–1. Th e concentrations of measured cations were high, e.g. the mean Na+ concentration was between 3.47 and 12.71 mgdm–3 and the mean Ca2+ concentration was between 7.96 and 10.21 mgdm–3. Th e mires of Sirok, Kelemér, and the Bereg region are separated on the basis of most variables. Th e mires of Bereg are less acidic and more rich in cations than the mires in Kelemér. Th e mire of Sirok (Nyírjes lake) was more similar to those of Kelemér than to the mires of the Bereg region. Th ere was no clear trend in sampling periods, but the most diverse group structure was found in September.
