“…Run-off and sewage discharges and industrial processes could be important sources of phosphates, phenol, nitrites, ammonium, toxic metals and wide spectrum of pharmaceutical and personal care products are typical pollutants (Falfushynska et al, 2010(Falfushynska et al, , 2014Rzymski et al, 2014).The kinds of Halina I. Falfushynska 1,2 , Lesya L. Gnatyshyna 1 , János Gyori 3 ,Oksana B. Stoliar pollution in these areas are well described by Zeybek et al (2012). The studied area in Western Ukraine corresponded to this criterion, since it is characterised by an unsteady level and composition of background pollution, punctuated by the occurrence of emergency situations.…”

The aim of the present study was to ascertain whether the metallothioneins (MTs) of freshwater mussels can serve as a biomarker of environmental quality in the spontaneously polluted area. Anodonta anatina mussels from an agricultural site (A), the cooling pond of a nuclear power plant (N) and a forestry as a reference site (F) in Western Ukraine were studied during spring, summer and autumn. Concentrations of copper (Cu), zinc (Zn) and cadmium (Cd) in MTs and in the tissue, MTs protein (MT-SH) level, oxidative stress indices and apoptotic activities were determined in the digestive gland. The three sites were clear distinguished by biomarkers. In the A-group, the specimens, despite higher concentrations of Cu and Zn in the tissue, had low level of MT-SH level (in two seasons) making the metal-keeping function of MTs invalid. MTs-bound metals dropped to about 2.3% of Cu, 0.4% of Zn and 9.1% of Cd in the tissue in autumn in this polluted area. Lower level of glutathione redox-index reflected the oxidative stress in this group. The N-group displayed high levels of MT-bound Cu (corresponding to up to 57.7% of the total tissue metal) and caspase-3 activity (up to 7 times higher than in the reference Fgroup), indicating specific for cooling pond pollution by Cu and thermal effects. In group F, the set of markers showed the characteristic of the reference site. An extremely low redox-index of glutathione (RI GSH: 0.45) was observed in the A-group in spring, and high levels of protein carbonyls and TBA-reactive substances in autumn in group N.Hence, multi-marker approach needed to provetoxicityassesments in mussel sexposed byspontaneous and mixed pollution.

“…However, some studies have revealed toxicity of most substances is affected by such factors as DO, water hardness and pH (Økland, 1990;Duft et al 2007). The comparative studies in aquatic molluscs have revealed that species' distributions are restricted by environmental conditions (Hunter, 1961;Økland, 1969;Dussart, 1976, Dillon, 2000Maltchik et al 2010;Zeybek et al 2012). As some are edible, many being agricultural pests or hosts to parasitic organisms, they have parasitological importance (Şeşen and Yıldırım.…”

This study was carried out by the streams of Tunceli province (Turkey) between June 2008 and May 2009 to determine Mollusca fauna. Samples were taken at 20 stations, seasonally. Mollusca fauna of the streams of Tunceli was represented by three species of Prosobranchia (Bithynia pseudemmericia, Bithynia tentaculata, Anadoludamnicola gloeri), four species of Pulmonata (Galba truncatula, Radix labiata, Physella acuta, Acroloxus lacustris), and two species of Bivalvia (Pisidium casertanum, Pisidium lilljeborgii). Canonical Correspondence Analysis (CCA) was applied to determine the relationships among the Mollusca fauna and physicochemical variables. CCA explained 31.897% of the species and environmental variation by the second axis. Water temperature (T), dissolved oxygen (DO), pH, and Ca +2were the most influential variables on the Mollusca fauna. The present study is the first research on the Mollusca fauna in the streams of Tunceli province. Molluscs species were recorded for the first time from the area.

“…The studies of freshwater macrobenthic invertebrates as biological monitoring techniques have been widely reported and described by the various researchers in Turkey (Kazancı and Dügel 2000;Duran et al, 2003;Balık et al, 2006;Kalyoncu and Zeybek, 2009;Türkmen and Kazancı 2010;Yıldız et al, 2010;Kalyoncu and Zeybek 2011;Zeybek et al, 2012;Kazancı et al 2013;Zeybek et al, 2014;Yıldız et al, 2015).…”

The study was carried out on Sürgü Stream, located in Malatya Province (Turkey), and aimed to determine the diversity and species composition of macrobenthic invertebrates. Six stations were determined on the stream and macrobenthic invertebrates were taken seasonally. As a result, 34 taxa belonging to five classes were detected; one of which belongs to Hirudinea, one of which belong to Arachnida, three to Gastropoda, five to Malacostraca and 24 to Insecta classes. Insecta was the most dominant group among the determined taxa. The Shannon Weaver Diversity Index and the Simpson Index showed that the lowest species diversity was observed at the third station while the highest species diversity was found at the second station. Also, UPGMA algorithm was used to show possible clustering relationships among the seven stations based on organisms. According to UPGMA analysis, the highest similarity value was observed between the first and second stations (87%), while the lowest similarity value was found between the second and fourth stations (13%). To date, there is no study on the determination of macrobenthic invertebrate fauna of Sürgü Stream. Therefore, all the identified taxa have been recorded for the first time for the study area.
