The aim of this study was to evaluate foundry waste used for various applications in terms of heavy metals quantity of fractions of their binding. The novelty of these studies is the use of speciation procedures to assess the fraction of heavy metals in foundry waste. The two most popular speciation procedures, the Tessier method and the SM&T, and also the TCLP single extraction procedure were used to evaluate the use of foundry waste in agritechnique, road engineering and construction in this research. Additionally, local soils were analyzed and compared to landfill foundry waste (LFW). It was found that LFW may have a negative impact on the natural environment when used for agrotechnological applications due to the increased concentration of mobile and bioavailable fractions (mean 9–18%) of metals. Foundry dusts were characterized by a low percentage of mobile and bioavailable (mean 2–6%) forms, although this does not include electric arc fournance dust (EAFD) (mean 17%). The metal content in TCLP extracts was low in all foundry waste samples and allowed the use of the analyzed wastes in construction and road construction. The usefulness of both speciation procedures for the assessment of the leaching of heavy metal forms from foundry waste was confirmed. However, the SM&T procedure was more effective in leaching mobile and bioavailable forms of heavy metals in foundry waste and soil samples.

The aim of the paper is to provide an answer to the following question: How to interpret the principle of acquaintance and what role does it play in Bertrand Russell’s epistemology? It seems that the principle itself should be so adjusted as to take into account two concepts: (1) an act of judgment as a multiple relation and (2) the division of reality into what is directly given (sense‑data) and physical objects. I show, contrary to Russell’s assurances, that the content and the role of the principle is not clear, and its acceptance leads to a paradox. Having discovered that consequence, Russell abandoned the dualistic division of reality and with the help of the method of logical constructions, sought a position that embraced phenomena

Johann Fidalke (1703–1763), a Gdansk pastor and a gymnasium teacher, gathered a substantial collection of books comprising more than 10,000 volumes. After his death, the books were sold during four auctions, and the valuable collection was dispersed. However, owing to an auction catalogue kept in the collections of the Gdansk PAS Library, we may recreate the content of the Gdansk pastor’s collection. Its most considerable part was made up of different editions of the Holy Bible – with a total of 95 editions in 156 volumes. The article provides a quantitative and qualitative analysis of the said Bibles, focusing on the presentation of their languages as well as the places and times of their publication, and their bindings. The article is accompanied by an index, in which the different editions of the Bible in Fidalke’s collection are identified and catalogued in line with the contemporary standards, on the basis of the rudimentary information given in the auction catalogue.
