Accumulation trends of metals and a metalloid in the freshwater crayfish Astacus leptodactylus from Lake Yenicaga (Turkey)
Tunca, Evren; Ucuncu, Esra; Kurtulus, Bedri; Ozkan, Alper Devrim; Atasagun, Sibel (Taylor & Francis Ltd, 2013)This study aims to determine the extent of metal pollution in Lake Yenicaa (Bolu, Turkey) by investigating the accumulation trends of five metals (Al, Cu, Fe, Ni and Zn) and a metalloid (As) in gills, exoskeleton, ... -
ASSESSMENT OF HEAVY METAL CONTAMINATION AND ACCUMULATION PATTERNS IN THE COASTAL AND DEEP SEDIMENTS OF LAKE SALDA, TURKEY
Çaldırak, Hüseyin; Kurtuluş, Bedri; Canoğlu, Mustafa Can; Tunca, Evren (Parlar Scientific Publications (P S P), 2017)In this study, contamination levels were found for 8 different metals (Cu, Pb, Zn, Ni, Mn, Fe, Cd, Cr) and metalloids (As) in sediment samples, coming from 9 different stations, through statistical analysis and sediment ... -
Assessment of trace metal pollution in the coastal sediments of Fethiye-Göcek Bay (SW Turkey) and evaluation of pollution sources
Gülşen-Rothmund, Halil İbrahim; Gülşen-Rothmund, Halil İbrahim; Arslan, Şebnem; Kurtuluş, Bedri; Tunca, Evren; Avşar, Ulaş; Avşar, Özgür (Elsevier Ltd, 2022)This research evaluated the trace metal pollution and the pollution sources in the coastal sediments of Fethiye-Göcek Bay by using the spatial distribution maps, correlation and statistical analysis, which were acquired ... -
DECREASE AND INCREASE PROFILE OF CU, CR AND PB DURING STABLE PHASE OF REMOVAL BY DUCKWEED (LEMNA MINOR L.)
Ucuncu, Esra; Tunca, Evren; Fikirdesici, Seyda; Altindag, Ahmet (Taylor & Francis Inc, 2013)The present work details the decrease-increase profiles of Cu, Cr, and Pb by the aquatic plant Lemna minor. A mixture of these metals were utilized at different concentrations. Removal profiles of each metal was determined ... -
Effects of laser ablated silver nanoparticles on Lemna minor
Üçüncü, Esra; Özkan, Alper D.; Kurşungöz, Canan; Ülger, Zeynep E.; Ölmez, Tolga T.; Tekinay, Turgay; Tunca, Evren (Pergamon-Elsevier Science Ltd, 2014)The present study investigates and models the effect of laser ablated silver nanoparticles (AgNPs) on the development of the aquatic macrophyte Lemna minor. Toxic effects of five different AgNP concentrations (8, 16, 32, ... -
Elemental accumulation in the surficial sediment of Kesikköprü, Çubuk II and Asartepe Dam Lakes (Ankara) and potential sediment toxicity
Fikirdeşici Ergen, Şeyda; Tekatlı, Çağrı; Gürbüzer, Pınar; Üçüncü Tuna, Esra; Türe, Hasan; Biltekin, Demet; Kurtuluş, Bedri; Tunca, Evren (Taylor and Francis Ltd., 2021)In this study, Çubuk 2, Kesikköprü and Asartepe Dam Lake, were investigated. A total of 60 sediment samples were collected and the concentrations of 10 elements (Cu, Pb, Zn, Ni, Mn, Fe, Co, Cr, Al, As) were determined. The ... -
Phytoremediation of Cu, Cr and Pb Mixtures by Lemna minor
Ucuncu, Esra; Tunca, Evren; Fikirdesici, Seyda; Ozkan, Alper Devrim; Altindag, Ahmet (Springer, 2013)The present study reports the capacity of the aquatic macrophyte Lemna minor to remediate combinations of Cu(II), Pb(II) and Cr(III) from a simulated natural environment. The effect of these metal mixtures on the growth ... -
SPATIAL AND TEMPORAL ASSESSMENT OF METAL(LOID) CONTAMINATION IN ASARTEPE DAM LAKE (ANKARA, TURKEY) USING POLLUTION INDICES AND MULTIVARIATE STATISTICAL ANALYSIS
