Item Participarea substanțelor tiolice în procese de autopurificare chimică a apelor naturale: Monografie(CEP USM, 2022) Blonschi, Vladislav; Gladchi, Viorica; Duca, GheorghePrezenta lucrare este consacrată evaluării aportului substanțelor tiolice în procesele de autopurificare chimică a sistemelor acvatice, prin stabilirea unor legități de transformare fotochimică ale acestora.Item Fotoliza directă a unor substanțe tiolice în mediul acvatic și rolul lor în procesele ecochimice din apele naturale [Articol](CEP USM, 2022) Lis, Angela; Gladchi, Viorica; Travin, SergheiItem Chimia ecologică a apelor naturale și procese de autopurificare a sistemelor acvatice [Articol](CEP USM, 2022) Gladchi, Viorica; Bunduchi, Elena; Blonschi, Vladislav; Romanciuc, LidiaItem Monitoringul conținutului substanțelor tiolice în unele ape de suprafață [Articol](CEP USM, 2022) Blonschi, Vladislav; Gladchi, Viorica; Bunduchi, ElenaItem Facultatea de Chimie şi Tehnologie Chimică a Universității de Stat din Moldova la 75 de ani [Articol](2021) Gladchi, Viorica; Dragalina, GalinaItem Compoziția chimică și poluarea apelor afluentului Nistrului, râului Ichel (perioada anilor 2015-2020) [Articol](Eco-TIRAS, 2021-02-01) Gladchi, VioricaItem Regional climate change and surface waters [Articol](2019) Duca, Gheorghe; Nedealcov, Maria; Travin, Serghei; Gladchi, VioricaThe actual period marred by the global warming requires expanding our knowledge on the regional particularities of climate changes manifestations as consequences of global climatic changes. It was stated that within the limits of Republic of Moldova’s territory the pace of warming is much more accelerated than the global one. These consequences, in their turn, had led to the increase in degree of evaporation of surface waters, which had conditioned the doubling of still water’s pollution in the region (Lake Beleu). We consider that the obtained results could contribute to the adequate management of water resources in the new climatic conditions.Item Self-purification of aquatic media from hexachlorocyclohexane in a radical process [Articol](2019) Travin, Serghei; Duca, Gheorghe; Gladchi, VioricaIt is known, that highly toxic pesticide hexachlorocyclohexane (HCH) is resistant to decomposition and has a long-term accumulating capacity. Nevertheless, it undergoes complete degradation in reactions with hydroxyl radicals in Fenton-like systems. The goal of this work was to study the influence of HCH on the processes of radical self-purification of water bodies and to explain the mechanisms of chemical transformation of substances occurring in natural waters, as well as to reveal the kinetic characteristics of the processes of radical self-purification of water bodies. It was found, that HCH plays a dual role for aquatic ecosystems – it is not only a scavenger of free radicals, but also an additional initiator. Under the influence of light in the surface layer of water, HCH generates radicals, thus contributing to the self-purification processes.Item Soluţii pentru prevenirea şi diminuarea consecinţelor inundaţiilor [Articol](2010) Duca, Gheorghe; Furdui, Teodor; Melniciuc, Orest; Zubcov, Elena; Gladchi, Viorica; Moraru, Constantin; Bogdevici, Oleg; Arnăut, Nicolae; Bujac, VictorThe danger of floods is very up to date for the Republic of Moldova, so, two types of flood are characteristic: transboundary, caused by Dniester and Prut rivers, and local, caused by discharges of small streams, lakes, ponds. A group of experts from the Academy of Sciences of Moldova developed solutions to prevent damages caused by triggering floods. Among these are: the creation of National center of flood monitoring; the assessment of flood areas and the liable to inundation potential of Dniester and Prut rivers and small streams; the elaboration of “Scheme of protection of populated localities against flood”; the regular water sampling in flood areas to monitor the state of pollution; the implementation of flash flood model; the agreement between Ukraine-Republic of Moldova-Romania on monitoring, forecasting and sustainable exploitation of aquatic ecosystems etc.Item Facultatea de Chimie şi Tehnologie Chimică a USM – tradiţii şi rezultate ştiinţifice [Articol](2011) Gladchi, VioricaThe paper reviews the developmental stages of the Faculty of Chemistry and Chemical Technology and the main results of scientific research in the Scientifi c Research Center “Applied and Ecological Chemistry” during the years 2006-2010.
