The environmental legislation in Ukraine is changing rapidly. These changes are related to the adaptation of Ukrainian laws to the requirements of the European Union. In this regard, the paper considers the unintentional production of Persistent Organic Pollutants (POPs) in the Odessa Industrial-and-Urban Agglomeration (next – Odessa agglomeration) in the context of new regulatory and legal requirements of Ukraine. In many countries around the world, the issue of pollution of environmental components by POPs has a large focus, because POPs pose a global threat to the environment and human health. The work aims to assess the main sources of unintentional production of POPs in the Odessa agglomeration during one year (2017), taking into account the new territorial features of the Odessa agglomeration. For the first time for Odessa agglomeration, the mass of POPs formed by main sources using the newest European methodological approach was calculated, sources of unintentional production of POPs on volumes of these substances were ranked, and their total mass of generation on the territory of Odessa agglomeration was calculated. The number of POPs molecules equivalent to 2,3,7,8-TСDD, which infiltrate into the air basin of the Odessa agglomeration, hence into the organisms of the agglomeration inhabitants, was calculated. The obtained results were compared with the allowable number per capita of the agglomeration, the relevant conclusions were drawn. Priority sources of unintentional production of POPs were identified, which allows taking appropriate preventive measures to reduce the scale of their generation.

The growth in the number of road transport is an integral part of Ukraine’s development. At the same time, this is a significant negative factor affecting urban ecosystems. In the paper, the most significant aspects and criteria for their evaluation were identified to assess the negative impact of the transport company on the urban ecosystem. The impact of the Kremenchuk Motor Transport Enterprise on the urban ecosystem of the city of Kremenchuk (Poltava region) was assessed. The main pollutants in the region’s air basin are stationary sources. However, the predominant sources of air pollution are emissions from mobile sources. The criteria for assessing the level of environmental safety of a motor transport enterprise were improved. The "Comprehensive assessment of the level of environmental safety of the motor transport enterprise" software tool was developed. It was established that under modern conditions, the level of environmental safety of the motor transport enterprise corresponds to the level of average safety. Comprehensive measures were proposed to ensure the regulatory status of the components of the urban ecosystem and environmental safety on the territory of the Kremenchuk Motor Transport Enterprise.

W artykule przedstawiono porównanie wyników komputerowej symulacji jakości powietrza w modelu pomieszczenia z rzeczywistymi wynikami pomiarów stężenia formaldehydu w powietrzu wewnętrznym. Zaprezentowano podstawowe elementy budowy modelu cyfrowego odzwierciedlającego fizyczne pomieszczenie, drogi przepływu powietrza, system wentylacji mechanicznej oraz źródło emisji substancji chemicznej. Wyniki symulacji zostały zestawione z wynikami badań jakości powietrza wewnętrznego zawierającymi między innymi oznaczenie zanieczyszczeń chemicznych.

The paper presents the comparison between the results of model room’ indoor air quality computer simulation and the real test results of formaldehyde concentration in indoor air. The essential elements of computer model reflecting the physical properties of the space, infiltration paths, mechanical ventilation system and the contamination sources are described. The simulation results were confronted with the IAQ test results, that included indication of chemical contaminants.

Na tle ogólnej instalacji do wytwarzania produktów ceramicznych w artykule scharakteryzowano prawdopodobne miejsca uwolnień zanieczyszczeń rekomendowanych dla przemysłu ceramicznego w rozporządzeniu PRTR. Skorelowano również miejsca uwolnień zanieczyszczeń z rodzajem uwalnianego zanieczyszczenia oraz komponentu, do którego następuje jego uwolnienie. Ponadto opisano zasady tworzenia bilansów zanieczyszczeń dla poszczególnych elementów ciągu technologicznego i określania wielkości uwolnień oraz transferów zanieczyszczeń zawartych w ściekach i transferu odpadów ujętych w rejestrze.

In the article on the general system for the manufacture of ceramic products, the likely site releases of pollutants recommended for the ceramics industry in the PRTR regulation were characterized. Also the correlation between sources of pollutants releases and type of this pollutants and the environmental component to which pollutants is released was made. Furthermore, the principles to create balance sheets for the various pollution of technological elements and transfers of pollutants in sewage and waste transfer included in the registry PRTR were described.

Nitrogen oxides are mainly produced by combustion at high temperatures and are formed by reactions between nitrogen and oxygen. People are mainly exposed to indoor nitrogen oxides. Indoor air can be contaminated from the use of gas for. heating and cooking appliance. The most important indoor source of nitrogen oxides is gas burning in the kitchen. The effect of wooden and plastic windows on the level of NOx concentrations is described in this article. It was confirmed necessarily of air change.
