The condition and quality of atmospheric air plays a very important role in the life of every living organism, including man. Every day we breathe atmospheric air containing CO2 whose level changes depending both on many external factors and physicochemical processes. The concentration of carbon dioxide in the air changes, among other things, due to the influence of communication routes which may adversely affect the environment. For this reason it is necessary to analyze changes in CO2 concentrations and try to determine their impact on the functioning of users of the area (so, one can observe and analyze seasonal impact of communication routes on separate sub-areas of research).

The main air pollutants in the sintering process of iron ore are polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans (PCDD/Fs) and harmful dust. Ore sintering on sinter strands is one of the first technology steps in the ironworks. It is a process in which iron ore is crushed, subjected to annealing and mixed with appropriate additives, and then sintered in order to produce sinter which is the main component of iron in the blast furnace process. PCDD/Fs emissions were measured and the addition of ammonium sulfate as an inhibitor of the synthesis of dioxins in the sintering process of iron ore was studied.

Do głównych substancji zanieczyszczających powietrze w procesie spiekania rud żelaza należą polichlorowane dibenzodioksyny i polichlorowane dibenzofurany (PCDD/PCDF), a także szkodliwe pyły. Spiekanie rud na taśmach jest jednym z pierwszych węzłów technologicznych huty o profilu surowcowym. Jest to proces, w którym ruda żelaza jest kruszona, poddawana wyżarzaniu i mieszana z odpowiednimi dodatkami, a następnie spiekana w celu otrzymania spieku, który stanowi główny składnik żelazowy w procesie wielkopiecowym. W aglomerowni wykonano pomiary emisji PCDD/Fs, a także badano dodatek siarczanu amonu jako inhibitora syntezy dioksyn w procesie spiekania rudy żelaza.

The article discusses issues related to the impact of incineration on human health and the environment. The aim of the work is to make a broad overview of the existing literature in this area. The problem was described in the literature based on a number of waste incineration plants studies in both Europe and all around the world. Subjects analyzed in the literature were risks at workplace, both administrative ones and directly related to the process of thermal treatment of waste. These risks result among others from the atmospheric emissions of many pollutants, including most of all polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans, heavy metals and some volatile organic compounds. The results of these studies will be an important argument in the discussion on the possible risks to humans and the environment posed by waste incineration plants and the expediency of building waste incinerators in Poland.

Thermal treatment of waste is one of the ways of their processing. It is commonly used in most developed countries of the European Union. Major by-products of the combustion processes are slag and bottom ash. In the majority of EU countries bottom ash and slag are used as a priming for road construction. In Poland slag and bottom ash from incineration process are stabilized with the addition of cement and some polymers and are landfilled as wastes. In accordance to Polish law, depending on the leaching of heavy metals from fly ash and slag after thermal treatment of waste can be regarded as both hazardous and non-hazardous wastes. At present work sequential extraction methods described in the literature: Tessier’s method, van Herck’s method and BCR method were compared experimentally with the results of using Swiss standard TVA.SA.1991 and European standard EN 12457 and total concentration of metals in sample analyzed after complete digestion of sample. The study sample was bottom ash from the medical waste incineration plant.

Termiczne przekształcanie odpadów jest jednym ze sposobów ich przetwarzania. Głównymi produktami ubocznymi procesu spalania są żużel i popiół paleniskowy. W większości krajów UE są one wykorzystywane gospodarczo. W Polsce żużle i popioły po termicznym przekształcaniu stabilizuje się z dodatkiem cementu i polimerów i składuje jako odpad. Zgodnie z obowiązującym prawem, w zależności od wymywalności metali ciężkich, żużel i popioły po termicznym przekształcaniu odpadów mogą być uznawane zarówno za odpady niebezpieczne, jak i inne niż niebezpieczne. W pracy porównano doświadczalnie metody ekstrakcji sekwencyjnej opisane w literaturze: metodę Tessiera, metodę van Hercka oraz metodę BRC. Badaniu poddano próbkę popiołu pochodzącą ze spalarni odpadów medycznych.
