Article Citation - WoS: 7Citation - Scopus: 8Enrichment of Trace Element Concentrations in Coal and Its Combustion Residues and Their Potential Environmental and Human Health Impact: Can Coal Basin, Nw Turkey as a Case Study(Inderscience Enterprises, 2016) Baba, Alper; Gürdal, Gülbin; Şanlıyüksel Yücel, DenizIn this study, the variation of trace element concentrations ( total of 48 trace elements including rare earth elements) in coal, coal ash and fly ash were examined and compared with coal Clarke values. Results showed that the average concentrations of trace elements including As, B, Cu, Ce, Co, Cs, Gd, Hf, La, Lu, Mo, Nd, Nb, Pr, Pb, Sc, Sm, Ta, Tb, Th, U, V, W, Y, Yb, Zn and Zr in the Can Basin coals are higher than their respective Clarke values for world low-rank coals. The elements As, Cu, Co, Cs, Mo, Nb, Sc, Pb, Pr, Th, U, V, Zn and Zr are enriched in coal ashes, whereas As, Co, Nb, Sc, U and V are enriched in fly ashes. Among the elements, maximum enrichment in coal was observed for As, with the average concentration of 253.5 ppm As in the Can Basin coals, while the coal Clarke value is 14 ppm and world average value is 8.3 ppm. From the ecotoxicological point of view, combustion residues formed by indoor combustion of coal and/or in thermal power plants may be a hazard to the environment and to aquatic and terrestrial life including human beings, particularly As, trace elements and released radioactive elements.Conference Object Drainage Waters Affected by Pyrite Oxidation in an Open Pit Coal Mine in Can Region, Nw Turkey(IAH Australia, 2013) Şanlıyüksel Yücel, Deniz; Baba, Alper; Şengün, Fırat; Yücel, Mehmet AliThe Yiğitler Mine is abandoned open pit coal mine in Can Region, nortwestern Turkey, about 46 km east of Çanakkale city...Conference Object Monitoring of Acid Mine Lakes by Unmanned Aerial Vehicle (uav) on Geographic Information System (gis) Around Can Region, Biga Peninsula, Nw Turkey(Muğla Sıtkı Koçman Üniversitesi, 2014) Yücel, Mehmet Ali; Şanlıyüksel Yücel, Deniz; Turan, Recep Yavuz; Baba, AlperIn the past three decades, a few small scale private enterprises have been operating around Can Region, Biga Peninsula, NW Turkey which is rich in lignite reserves. They have abandoned the operation land without providing any working of rehabilitation. during the operation of high sulfur content lignite, the topography have been damaged and this caused the large holes and deterioration in these areas. As a result of discharge of surface water the artificial lakes have been formed. In the course of the time, these lakes gain acidic character due to acid generation from pyrite oxidation. Significantly high acidity with low pH values ranging from 2.53 to 3.05 is recorded from AMLs.Conference Object Hydrogeochemical Characteristics of Acidic Water Sources Around Can Region, Biga Peninsula, Nw Turkey(Muğla Sıtkı Koçman Üniversitesi, 2014) Şanlıyüksel Yücel, Deniz; Baba, AlperAcid rock drainage (ARD) is one of the major sources of water pollution in some countries. Densely generation of ARD have been seen around Can Region (Biga Peninsula-NW Turkey) due to altered (silicification, argillic alteration) volcanic rocks which contain sulfide minerals and specially pyrite and there is inadequate availability of neutralizing carbonate minerals. Forty water samples (including 17 drilling, 5 drinking water, and 18 spring water) were collected from 2011 to 2012. The result show that pH of water samples is lower than 5 in most part of study area.Conference Object Assessment of Water Quality Related To Lead/Zinc Mines in Umurbey Dam Basin, Northwestern Turkey(International Water Association, 2017) Şanlıyüksel Yücel, Deniz; Baba, AlperThe purpose of this study is to determine hydrochemical properties of the water resources and to assess the potential environmental consequence of the mining activities in Koru and Tesbihdere lead/zinc mine districts, and investigate detrimental effects caused by mining activities on the water resources and sediment quality in Umurbey dam basin (Biga Peninsula, NW Turkey). Cadmium, Cu, Fe, Mn, Pb and Zn concentrations in sediments downstream of Tesbihdere and Koru mines and in Umurbey dam sediments are higher than average values of world river sediments.Conference Object Çan (çanakkale) İlçesinin Gb’sindaki Su Kaynaklarının Hidrojeokimyasal Özellikleri(TMMOB Jeoloji Mühendisleri Odası, 2015) Şanlıyüksel Yücel, Deniz; Baba, AlperÇalışma alanı ülkemizin KB’sında yer alan Çanakkale iline bağlı Çan ilçesinin GB’sında Muratlar, Halilağa, Keçiağılı ve Hacıkasım köyleri arasında yer almaktadır.

Muratlar Region in the northwest of Turkey is one such area having complex geology of widespread volcanic succession with active tectonics and geothermal fluids. This natural setting serves as a suitable environment for the presence of high levels of arsenic in groundwater in Muratlar Region. Arsenic was determined to be presented in water samples taken from wate resources in the Muratlar Region during 2009-2010. High concentrations of arsenic were seen in the east of Muratlar Region, where densely settled argillic alteration outcrops were present. The maximum As concentration was 150 ppb. Chemical analyses revealed that arsenic was exceeding the maximum allowable limits depicted in the national and international standards for drinking water quality. The main reason for obtaining high arsenic concentrations is related to longer retention times of water resources in altered (argillic, silicification) volcanic rocks. Water-rock interaction is an important mechanism in determining the overall quality pattern of groundwater resources in this region.Article Türkiye’de Asit Maden Göllerine Çan (çanakkale) Havzası’ndan Güncel Birkaç Örnek(TMMOB Jeoloji Mühendisleri Odası, 2013) Şanlıyüksel Yücel, Deniz; Baba, AlperMadencilik faaliyetinin su kirliliğine neden olan birincil kaynağı asit maden drenajı/gölleridir.

Mining activities in Koru, one of the longest operated mines in NW Turkey, date back to the beginning of the 1900s. The purpose of the study is to (1) determine the hydrochemical properties of the water resources and to assess the potential environmental consequences of mining activities in the Koru and Tesbihdere mining districts, and (2) investigate the effects caused by mining activities on the water resources and sediment quality in the Umurbey dam basin. Concentrations of As, Cd, Cu, Fe, Mn, Pb, and Zn in river sediments downstream of the Tesbihdere and Koru mining district, and in the Umurbey dam sediments were higher than the world average for river sediments. The geoaccumulation index and enrichment factor revealed that sediments were strongly polluted with Pb and Zn, moderately to strongly polluted with Cd and moderately polluted with Cu. The chemical analyses of water resources revealed that the maximum Fe, Zn, Pb, Mn, and Cu concentrations reached 2890 μg/l, 1785 μg/l, 1180 μg/l, 984 μg/l, and 419 μg/l, respectively. The Koru River is classified as polluted water according to Turkish inland water quality regulations. The environmental contamination problems in the local drainage system are caused by leakage from past and current tailing ponds into the Koru River.
