In this study, we aimed to determine the effect of domestic and agricultural discharge on level antioxidant vitamins A, E, C, β-carotene malondialdehyde (MDA, an indicator oxidative stress) in muscle tissue freshwater mussel as known bioindicator (Unio elongatulus eucirrus). The mussels were collected from Arguvan (uncontaminated reference site) Battalgazi (exposed Karakaya Dam Lake. order exam...

In 2018 and 2019, quantitative aquatic macroinvertebrate samplings were carried out in the river network of Bükkösdi-víz (Mecsek Mountain). The identification 325,865 specimens originated from 40 sampling sites resulted occurrences 125 different species belonging to 12 higher taxa (Gastropoda – 9, Bivalvia 1, Hirudinea 4, Malacostraca 6, Ephemeroptera 16, Odonata 12, Plecoptera 3, Heteroptera 1...

The current work investigated the ecotoxicological effects induced by Titanium Dioxide (TiO2) nanoparticles (NPs), used at three different concentrations (C1 = 10 ?g·L?1, C2 100 ?g·L?1 and C3 1000 ?g·L?1) in a laboratory experiment, on freshwater mussel Unio ravoisieri. Biochemical analyses of gills digestive glands revealed stress-related disruption antioxidant system. catalase activity rates ...

Varga Gyula halalaval a magyar agrargazdasag kiemelkedő ismerőjet, szakertőjet vesztettuk el – magam pedig egy igaz baratot is. Negy even at egyetemi csoporttarsak, egyuttal kollegiumi szobatarsak voltunk. Baratsagunkat erősitette kozos csaladi hatterunk: falusi neptanito szuleink falu, mezőgazdasag es paraszti elet jobbitasa es felemelkedese melletti elkotelezettseget neveltek belenk. ezt a...

Many chlorinated phenols and their derivatives are used extensively as insecticides, fungicides and herbicides by industrial and agricultural users throughout the world. Among these substances, pentachlorophenol (PCP) is a broad-spectrum biocide, which is still used as a wood preservative. In this paper, the digestive gland cells were used to assess the effect of PCP in the range of concentrati...

Abstract Freshwater bivalves are key faunal elements of aquatic ecosystems. Native species declines paralleled by increasing distribution and abundances non-native species. Appropriate management both groups depends on knowledge their interactions, which remains limited. Herein, we systematically review the current status native in Europe, analyzing functional interactions as well niche overlap...

in this paper, the metazoan parasite community system of capoeta damascina in the tigris basin (mesopotamian region) in the middle-east is presented. overall, 54 species have been identified. between 2005 and 2008, iranian surveys of capoeta damascina found a total of 47 metazoan parasites species, most identified to species level. in addition, 6 parasite species from iraq and 1 species from oc...
