The investigations of iron-containing phases existing in fly ashes were performed using transmission Mössbauer spectrometry. The examined samples of fly ashes were collected from different coal combustion systems, that is, stoker-fired boiler in municipal heating plant and pulverized coal boiler in power plant. Several phases are identified in the samples: iron oxides, paramagnetic aluminosilicate glass with Fe3+ ions and Al2O4-type spinel with Fe2+ ions. It was pointed out that proportions of contents of phases strongly depend not only on the combustion temperature but also on the way of ash collection.

The paper presents a solid inorganic peroxy compounds description (calcium peroxide, magnesium peroxide and sodium percarbonate) focused on the properties and environmental application, particularly for the degradation of polycyclic aromatic hydrocarbons (PAHs) and phenols in soil environment. Modern technological processes require the use of compounds that are safe for the environment, non-toxic, easily degradable to the products, which themselves have no adverse environmental effect. Peroxides, as the chemical compounds, produce an effect on the enzymatic activity of the environment into which they are introduced. A good indicator of the activity of soil, bottom sediment or activated sludge, may be the dehydrogenase activity, which is a reflection of the general physiological state of microorganisms. Peroxides can be applied both in a pure form, as well as in mixtures with certain other groups of compounds. To enhance their efficiency they can be mixed with nitrogen, phosphorus or potassium carrying compounds.

Our concern in this paper is to review four kinds of mesoporous silica materials which can be used as potential sorbents for pharmaceuticals. It is known that a continuous development of science, medicine and food industry has an effect on contamination of the natural environment. Moreover, many impurities, such as drugs, vitamins or proteins etc., which get into environment from urban and hospital wastes, can also influence on human organisms. Thus, there is a need to control an amount of those compounds, especially in the natural waters and wastewaters [1-4]. In this work, we present four types of silica materials which can be helpful in water purification by using adsorption process.

Plastic is undoubtedly the most convenient type of packaging, but at the same time it is not ecologically friendly. The widespread use of packaging materials all over the world makes us think more and more about the harm of plastic to the environment and humans. It does not decompose in natural conditions and accumulates in huge quantities, because it is mostly used as a single-use packaging. Therefore, the development of environmentally friendly biodegradable edible films and coatings is relevant. Edible food packaging is an important step in food production and one of the innovative directions of food packaging development. This article presents materials on the development of the formulation and manufacturing technology of new composite materials based on sodium alginate and chitosan for the production of edible coatings and films. The results of the physical, chemical and bactericidal properties of these materials are presented.

The development of chemical industry has brought civilization and economic benefits. Nowadays it is hard to image the everyday life without chemical products whose usage raises living standards. Unfortunately, the civilization development, where chemistry significantly contributed, caused unfavourable changes in natural environment. In order to stop further environment degradation, different initiatives are being taken up. They also concern activities in favour of chemical threats reduction. Particular role among those activities plays the concept of green chemistry which lists in the framework of sustainable development. One of the methods implementation of sustainable development rules is the properly conducted education in formal and non-formal dimensions. Education Decade for Sustainable Development announced by United Nations General Assembly, testifies its importance. The paper brings a closer current model of ecological (environmental) education on different teaching stages. A method of diagnostic survey was used in order to estimate the level of students` ecological awareness. The research is a continuation of our previous works. A survey was chosen as a research technique, and a questionnaire was a research tool. The questionnaire included 22 questions (closed and half-open ones). The research took into consideration only selected elements of ecological awareness. A special attention was paid to estimation of students` knowledge chemical threat aspects and protection of natural environment. Moreover, the paper presents historical outline of chemical industry development and its significance for civilization. The idea of green chemistry and its educational importance was shown as an example aiming at the reduction of chemical threats.

Rozwój przemysłu chemicznego przyniósł korzyści cywilizacyjne i ekonomiczne. Dziś trudno wyobrazić sobie życie codzienne bez produktów chemicznych, których wykorzystanie podnosi standard życia. Niestety postęp cywilizacyjny, do którego chemia wniosła istotny wkład, przyczynił się także do niekorzystnych zmian w środowisku naturalnym. Aby zahamować dalszą degradację środowiska, podejmowane są różne inicjatywy. Dotyczy to także działań na rzecz zmniejszenia zagrożeń chemicznych. Szczególne miejsce wśród tych działań zajmuje koncepcja zielonej chemii, która wpisuje się w ramy zrównoważonego rozwoju. Jednym ze sposobów wdrażania zasad zrównoważonego rozwoju jest właściwie prowadzona edukacja w wymiarze formalnym i nieformalnym. O ważności edukacji świadczy ogłoszenie przez Zgromadzenie Ogólne ONZ Dekady Edukacji dla Zrównoważonego Rozwoju (UN Decade for Education on Sustainable Development). W pracy przybliżono aktualny model edukacji środowiskowej (ekologicznej) na różnych etapach kształcenia. Aby ocenić stan świadomości ekologicznej studentów, przeprowadzono badania metodą sondażu diagnostycznego. Badania te stanowią kontynuację wcześniejszych prac. Jako technikę badań wykorzystano ankietę, a narzędziem badawczym był kwestionariusz, który zawierał 22 pytania (zamknięte i półotwarte). W badaniach uwzględniono tylko niektóre składniki świadomości ekologicznej, szczególną uwagę poświęcając ocenie znajomości przez studentów chemicznych aspektów zagrożeń i ochrony środowiska naturalnego. Ponadto w pracy przedstawiono rys historyczny rozwoju przemysłu chemicznego i jego znaczenie dla cywilizacji. Jako przykład działań zmierzających do zmniejszenia zagrożeń chemicznych opisano ideę zielonej chemii i jej edukacyjne znaczenie.
