The Sea of Azov is the smallest and shallowest sea in the world with low salinity. Such properties determine its susceptibility to degradation due to anthropogenic activities. The Azovstal Iron & Steel Works in Mariupol (Ukraine) is one of the main sources of pollution of the Azov Sea. Adverse impact of the steelworks is associated primarily with the large amount of technological and cooling wastewater discharged into the sea. The paper presents the impact assessment results of wastewater discharge on the sea water quality and the ecological conditions in the discharge zone. The assessment was performed using local Ukrainian methodologies as well as applicable surface water quality standards. The comprehensive assessment was based on the three numerical integrated indicators of sea water quality: the Water Quality Index (WJW), the Water Pollution Index (WZW), the Integrated Ecological State Index (ZWSE), and the so called principle of aggregation. Based on the assessment results it was demonstrated that the wastewater discharge from the Azovstal Iron & Steel Works leads to significant increase in water pollution in the coastal zone which brings threat to the marine ecosystem and limits all types of water consumption.

Propylene oxide polymerization in the presence of layered double hydroxides with different concentration of basic sites on their surface has been studied. It is shown that the polymerization can be catalyzed by both basic and acidic sites. On the basis of kinetic experiments the mechanisms of reaction undergoing were proposed.

W artykule badano polimeryzację tlenku propylenu w obecności warstwowych wodorotlenków podwójnych o różnej ilości centrów zasadowych na powierzchni. Wykazano, że kataliza polimeryzacji zachodzi zarówno w centrach zasadowych, jak i kwasowych. Na podstawie doświadczeń kinetycznych zaproponowano mechanizmy reakcji.
