Abstract
The objectives of this research were to determine and compare the heavy element concentrations in two study areas in Erzurum Turkey Aşkale and Dumlu sites Assessment of some heavy elements in sediment water fish Chondrostoma regium tissues and some aquatic insects Coleoptera Hydrophilidae were carried out in June to August 2014 Heavy element levels in aquatic insect samples and their associated water and sediment were analyzed by energy dispersive Xray fluorescence EDXRF spectrometer Fish tissues from the same habitat were measured by inductively coupled plasma mass spectrometry ICPMS Eleven elements Al Cr Mn Fe Ni Cu Zn As Cd Hg Pb were measured in fish tissues and 14 elements Ti V Cr Mn Fe Co Ni Cu Zn As Se Sr Br Pb were measured in insects According to the results it can be said that insects were contaminated by water and sediment thus accumulated higher concentration of some elements than their environment The fish which was caught from Aşkale station accumulates significantly higher level of heavy metals than Dumlu station’s fish The results were compared with national and international standards The values of some heavy elements were found at higher concentration than the acceptable limits The possible consequences of these results are briefly discussed from the point of potential hazards to ecology and human health Element concentrations in fish tissue are below the limits which are proposed by Turkish Food Codex FAO/WHO and EC and safe for human consumption in the edible parts of fish species in the regionsThis research is based upon first author’s Ph D thesis supported by Ataturk University Scientific Research Project under award number SRP162/2012 and SRP477/2012 The authors express their sincere gratitude to Dr Buğrahan EMSEN of the Department of Biology at the University of Karamanoğlu Mehmet Bey for statistical analysis of samples Also thanks for Mucip GENİŞEL Ağrı İbrahim Çeçen University to analysis of heavy elements in fish tissues
