The fate of phytoplankton communities in different hydrological and hydrochemical conditions was studied in the middle basin of the Biebrza River (NE Poland). Our results showed that hydrological connectivity significantly influenced phytoplankton abundance in floodplain lakes: minimal abundance was stated in lotic and maximal in lentic waterbodies. Phytoplankton diversity and species richness were related to changes in water levels. During the low-water phase, phytoplankton biodiversity was the lowest in lentic and the highest in lotic lakes. High water levels promoted exchanges in species among waterbodies and the river, which increased biodiversity indices. We concluded that the isolation of any floodplain lake from the river channel deteriorates its trophic conditions. Thus, the decrease in phytoplankton biodiversity in floodplain lakes should be regarded as an indirect feedback of the hydrobionts on the hydrological factors.

Changes in habitat conditions in the area of Eastern Poland (Polesie Podlaskie), often associated with anthropopressure, cause a reduction in the number of locations and population size of valuable and rare bog plant species, including a Pleistocene boreal relict, Salix myrtilloides. The aim of this study was to determine the current conditions of occurrence of this species based on the physico-chemical parameters of peatland piezometric groundwater. The results confirm the declining trend in the number of locations and abundance of this species in the past few decades, but at the same time they confirm the wide range of amplitude of the many investigated factors. Among the groundwater parameters studied, the low level of nitrogen fractions, phosphorus fractions, cations, and DOC can be considered to be a set of conditions promoting the preservation of the Salix myrtilloides population. The higher concentrations of phosphates, sulfates, Na, Ca, and Mg as well as higher pH and electrolytic conductivity can be considered to be presumably unfavorable. The lack of significant differences in the values of the piezometric water factors investigated for the sites with different population sizes of the studied species requires the identification of other limiting factors and the implementation of programs for its active protection in Poland.

The influence of selected physicochemical factors on the degradation of five PAHs in river water and distilled water was tested. Even in darkness, in distilled water some losses of PAHs were observed, different for various compounds, from 22% to 41% after 21 days. Aeration with air increased the losses of PAHs. But very high degradation was found when samples were irradiated with light, for some PAHs up to 90%. The loss of PAHs in river water occurred much faster then in distilled water. The changes in PAH concentrations in distilled water could be described by first order reaction. The equation was proposed and the half-lives were calculated. In river water two stages of degradation were noticed. The different PAHs showed the different degradation, the fastest process was for benzo[a]pyrene and indeno[c,d]pyrene.
