In order to overcome resistance to individual pesticides and improve their effectiveness, formulations containing two or more active substances are constantly being developed and put on the market over recent years. Mixtures of residual amounts of pesticides can be present in water and food and enter the human and animal bodies. However, the combined effect of pesticides on living organisms, including genetic structures in cells, has not been studied enough and it is not yet possible to predict the genotoxic effects of their mixtures based on available data. The purpose of this review was to collect and summarize literature information on the genotoxicity of pesticide combinations obtained at different objects. The results of studies conducted in different countries of the world are discussed, examples of detected synergistic, additive and antagonistic effects are given, indicating the need for testing the genotoxicity of preparative forms of pesticides containing several active substances, as well as mixtures of jointly used pesticides in order to ensure the safe use of pesticides for public health.

Àbstract Available literature information on triple point or melting point isotope effects (and related physical properties) is subjected to thermodynamic analysis and consistency checks. New values for the melting point isotope effects for C6H6/CgD6 and c-C6H12/c-C6D12 are reported. 6Li/7Li melting point isotope effects reported recently by Hidaka and Lunden (Z. Naturforsch. 49 a, 475 (1994)) for various inorganic salts are questioned

The bee Melipona scutellaris is considered the reared meliponine species with the largest distribution in the North and Northeast regions of Brazil, with records from the state of Rio Grande do Norte down to the state of Bahia. Considering the importance of this species in the generation of income for family agriculture and in the preservation of areas with natural vegetation, this study aimed at providing knowledge on the distribution of natural colonies of M. scutellaris in the state of Bahia. Literature information, interviews with stinglessbee beekeepers, and expeditions were conducted to confirm the natural occurrence of the species. A total of 102 municipalities showed records for M. scutellaris, whose occurrence was observed in areas ranging from sea level up to 1,200-meter height. The occurrence of this species in the state of Bahia is considered to be restricted to municipalities on the coastal area and the Chapada Diamantina with its rainforests. Geographic coordinates, elevation, climate and vegetation data were obtained, which allowed a map to be prepared for the area of occurrence in order to support conservation and management policies for the species.

The stages of the formation of Japanese art collections on the territory of Ukraine from the beginning of the 19th century to the present are highlighted on the basis of archival materials, periodicals and professional literature. Information about Japanese collections of the pre-war and post-war periods are systematized, while their composition and sources of formation are determined. The influence of the socio-political system on the development of the process of collecting Japanese art in Ukraine is also analysed. The sources of the formation of collections of Japanese art in the collections of The Bohdan and Varvara Khanenko National Museum of Arts in Kyiv, Odessa Museum of Western and Oriental Arts, the Chinese Palace of “Zolochiv Castle” Museum-Reserve, as well as Kharkiv Art Museum are explored. Finally, modern tendencies in the collection of Japanese art in Ukraine are determined.
