Wpływ Niekontrolowanych Wysypisk Odpadów na Niektóre Chemiczne Właściwości Gleb Organicznych Oraz Mineralnych Wytworzonych z Glin i Iłów w Województwie Zachodniopomorskim


Water quality of the Glebokie Lake in Szczecin (NW-Poland) was studied in years 2012-2014. Glebokie Lake is a reservoir with a negative water balance related to the location draining groundwater drinking water intake for Szczecin agglomeration. In 2004 hydrotechnical regulations were conducted aimed at maintaining a constant amount of water in the lake, which involved a temporary feeding Glebokie Lake with Gunica River waters. In order to determine the hydrochemical status of the Lake waters and the factors shaping water quality - 19 water quality indices within 25 months were measured: temperature, pH and water oxygen status, nutrients (N, P) and ionic macrocomponents and Fetot. Trophic status of the lake waters using the Carlson criteria was defined. On the basis of chemometric analysis of measurement data (CA, PCA/FA and DA) we established that statistically significant factors affecting water quality in the study period were: seasonal (the climatic seasons) changes in the biological processes activity, periodical (in April and November) waters inflows from the Gunica River, anthropopressure in during swimming season and the coagulant (FeSO4) presence in the ecosystem. The possibility of applying the chemometric techniques to interpret measurement data in the lake type like Glebokie Lake with a small amount of data has been shown.


Parent material of moorsh-like soils in Poland usually are mineral formations of fluvio-glacial origin or limnic limestone. The aim of the studies was to determine selected chemical properties of moorsh-like soils developed from mineral deposits and limnic limestone located within the province of Western Pomerania (north Poland). The studies showed that the chemical properties of the moorsh-like horizon (Au) are considerably affected by the underlying material. The horizon developed from limnic limestone contained statistically significant higher amounts P, Ca, Mg, Fe, Mn, Cu, Pb, Ni, and Co compared to the moorsh-like horizon developed from fluvio-glacial sands. No statistically significant influence of the underlaying material on the content of K, Na, Zn and Cd in the surface horizon was found.


Therefore the carried out study aimed at determination of the effect of high-calcium brown coal ash and compost being produced from municipal sewage sludge on the content and bioaccumulation of heavy metals in potato tubers, wheat grains and rapeseeds during a three-year period. Rapeseeds contained most Cd whereas wheat rains less. Potato tubers, wheat grains and rapeseeds contained more Mn, Ni and Zn in the fertilization objects with municipal sewage sludge with or without coal ash and compared to those where calcium carbonate or coal ash had been introduced into the soil at a dose corresponding to 1.5 Mg CaO · ha–1 at the beginning of this study. Differences in the Mn, Ni and Zn contents in test plants between the fertilization objects with sewage sludge of with and without addition of ash were not significant.
