Limiting partial molar volumes and expansibilities of ammonium perchlorate, tetraalkylammonium perchlorates, and tetrabutylammonium tetraphenylborate in N,N-dimethylformamide
PublicationWyniki pomiarów gęstości i szybkości rozchodzenia się dźwięku w roztworach nadchloranu amonu, nadchloranów alkiloamoniowych i tetrafenyloboranu tetrabutylomoniowego w N,N-dimetyloformamidzie wyznaczono wartości graniczne cząstkowych molowych objętości i rozszerzalności. Dokonano rozdziału tych wartości na udziały jonowe. Przeanalizowano wpływ temperatury oraz długości łańcucha na te wielkości.

Metals and metal-binding ligands in wine: Analytical challenges in identification.
PublicationBackground Due to important role of metals in the vinification process as well as their impact on the human health, their content in this alcoholic beverage has been extensively studied by many researchers. It is already known that speciation of metals determines their toxicity and bioavailability as well as influences their activity. Understanding the chemistry and knowing the structures of metal complexes could have relevant...

Bioaccumulation of metals in tissues of marine animals, Part II - metal concentrations in animal tissues
PublicationThe bioaccumulation of metals in an animal depends on a multitude of factors: biotic ones, like its body dimensions and mass, age, sex, diet, metabolism and position in the trophic web, as well as abiotic ones such as the distribution of metals in its environment, the salinity, temperature and pH of the water, habitat type, interactions with other metals. But it is diet that has the greatest influence on the accumulation of metals...

The occurrence of heavy metals and metal-resistant bacteria in water and bottom sediments of the Straszyn reservoir (Poland)
PublicationThe aim of this study is investigate the distribution of selected heavy metals (zinc, copper, lead, cadmium) and metal-resistant bacteria in water and bottom sediments of drinking water reservoir for Gdańsk (Poland). The research area - Straszyn Lake is a dam reservoir on Radunia river, of the total volume of 3 mln m3. Sediment and water sampling took place between May and October 2013 (eight series). Regarding metal concentration...
