Publikováno v: Water Science and Technology. 69:1834-1845

We investigated changes in the spatial distribution of phosphorus (P) and nitrogen (N) in the deep, mesotrophic Lake Hańcza. The raw data collection, supported by global navigation satellite system (GNSS) positioning, was conducted on 79 sampling po

Autor: Julita Dunalska, Daniel Szymański, Jolanta Grochowska, Izabela Bigaj, Rafał Zieliński

Publikováno v: Limnological Review; Volume 13; Issue 3; Pages: 181-188

The aim of this study was to compare the concentration of nitrogen and trace the dynamics of its changes in two lakes with different intensity of anthropogenic pressure. The dominant land use of Lake Paskierz catchment is built-up areas, while in Lak

Comparison of Coagulation Behaviour and Floc Characteristics of Polyaluminium Chloride (PAX 18, PAX XL19H, ALCAT) with Surface Water Treatment

Autor: Julita Dunalska, Daniel Szymański, Renata Brzozowska, Michał Łopata, Izabela Bigaj, Rafał Zieliński, Grzegorz Wiśniewski

Publikováno v: Limnological Review; Volume 13; Issue 2; Pages: 73-78

Coagulation behaviour of polyaluminium chloride (PACl) was comparatively investigated in terms of the removal of turbidity and colour with surface water. The growth of flocs was also compared. The results show that the decrease in saturation and valu

Bottom Sediments as a Potential Source of Phosphorus in the Riverine-Lacustrine System of the Kośna River (Northeastern Poland)

Autor: Izabela Bigaj, Daniel Szymański, Rafał Zieliński, Michał Łopata, Julita Dunalska

Publikováno v: Limnological Review; Volume 12; Issue 3; Pages: 115-124

Sediments from hypereutrophic Lake Łajskie localized in northeastern Poland were examined on the basis of P-fraction. The sediments were collected at five sampling sites. In the investigated lake, the rank order of P-fractions was HCl-P > BD-P > NH4

Characteristics of Bottom Sediments of Lake Widryńskie

Autor: Julita Dunalska, Michał Łopata, Daniel Szymański, Izabela Bigaj, Rafał Zieliński

Publikováno v: Limnological Review; Volume 12; Issue 4; Pages: 205-210

The aim of this study was to determine the chemical composition of Lake Widryńskie bottom sediments (max. depth. 27.0 m, area 123.9 ha). The sampling of bottom sediments was conducted once, on 16 August 2010. Sampling was made in 10 specific areas.
