Item ASSESSMENT OF THE SELF-PURIFICATION CAPACITY OF VALEA MORILOR’S LAKE(Academia de Ştiinţe a Moldovei, 2017) Bunduchi, Elena; Goreaceva, Nelly; Lutenco, MariaItem THE BUFFERING CAPACITY OF THE WATERS OF SOME LAKES FROM CHISINAU(Academia de Ştiinţe a Moldovei, 2014) Bunduchi, Elena; Gladchi, Viorica; Goreaceva, NellyItem CHEMICAL COMPOSITION, PROCESSES OF POLLUTION AND AUTOPURIFICATION OF THE GHIDIGHICI LAKE WATERS (2015-2018)(Academia de Ştiinţe a Moldovei, 2019) Gladchi, Viorica; Goreaceva, NellyItem FORMELE DE MIGRARE A CUPRULUI ŞI FIERULUI ÎN APELE NISTRULUI MEDIEVAL(CEP USM, 2007) Borodaev, Ruslan; Goreaceva, Nelly; Gladchi, Viorica; Bunduchi, Elena; Cutter, Gregory C.; Cutter, LindaThe investigation of the migration form of metals in the water environment presents scientific and applicative interest for the understanding of the factors affecting the concentration of metals, their reactivity, biological availability and toxicity.The results of the investigations of migration forms of copper and iron in the waters of the Dniester River on a site located between Naslavcea and Dubasari are presented in this paper. It is shown, that metals are transported through the river basically in suspended form which makes from the total amount in average 65.5 - 86.3% for copper and 74.1 – 99.8% for iron.Item IMPACTUL AFLUENŢILOR DIN DREAPTA ASUPRA CALITĂŢII APELOR FLUVIULUI NISTRU ÎN PERIOADA DE PRIMĂVARĂ A ANULUI 2009(CEP USM, 2010) Duca, Gheorghe; Gladchi, Viorica; Goreaceva, Nelly; Bunduchi, Elena; Borodaev, Ruslan; Lis, Angela; Anghel, Lilia; Şurîghina, Olga; Romanciuc, LidiaAmong the main factors that affect water quality of the main water resources of our country, which also ensures the economic development of the Republic, may be named the chemical flow of the tributaries waters and hydro-technical facilities, such as storage tanks.In this paper are exposed the results of researches related to the chemical composition of waters at the mouth of the tributaries of the right bank of the Dniester River - Raut, Ichel, Bic, Botna, as well as the chemical composition ofDniester waters upstream and downstream of the mouth of the mentioned above tributaries.Item THE INFLUENCE OF BENZOIC ACID ON THE RADICAL SELFPURIFICATION PROCESSES IN NATURAL MEDIUM(Tipografia Academiei de Ştiinţe a Moldovei, 2005) Gladchi, Viorica; Goreaceva, Nelly; Rusu, NicoletaItem MINERAL FORMS OF BIOGENIC COMPONENTS IN THE WATERS OF THE MIDDLE NISTRU(Academia de Ştiinţe a Moldovei, 2014) Goreaceva, Nelly; Gladchi, Viorica; Borodaev, Ruslan; Lis, AngelaItem ORGANIC SUBSTANCES IN THE MIDDLE DNIESTER WATERS(Academia de Ştiinţe a Moldovei, 2017) Gladchi, Viorica; Goreaceva, Nelly; Bunduchi, ElenaItem REDOX TRANSFORMATION PROCESSES OF THE REACTIVE BLUE DYE(Academia de Ştiinţe a Moldovei, 2014-05-28) Bunduchi, Elena; Gladchi, Viorica; Duca, Gheorghe; Goreaceva, Nelly; Lutenco, MariaItem ROLUL PESTICIDELOR DDT ŞI DDE ÎN PROCESELE DE AUTOPURIFICARE A SISTEMELOR ACVATICE(CEP USM, 2008) Gladchi, Viorica; Goreaceva, Nelly; Romanciuc, Lidia; Buga, ElenaResearch scope: Investigation of the DDT, DDE influence on the processes of water systems chemical self-purification. Based on the conducted research, the e ffective constants of pesticide interaction with the OH-radicals, inhibition ability of water medium were calculated. Besides, the stationary concentrations of OH-radicals were determined. The obtained results have high scientific and applied level of significance. The kinetic regularities, which were studied based on the model systems, could be applied to the natural water objects and used as important indicators to estimate the effectiveness of radical purification processes.Item THE STUDY OF REDOX CONDITIONS IN THE DNIESTER RIVER(Tipografia Academiei de Ştiinţe a Moldovei, 2005) Gladchi, Viorica; Goreaceva, Nelly; Borodaev, Ruslan; Mardari, Iurie
