Comparative study of heavy metals and selenium accumulation in the digestive gland and gills of Mytilus galloprovincialis (Lamarck, 1819) caught in Izmir bay (Turkey) [İzmir Körfezi'nden (Türkiye) yakalanan Mytilus galloprovincialis (Lamarck, 1819)'un sindirim bezi ve solungaçlarındaki ağır metal ve selenyum içeriklerinin karşılaştırması]
ABSTRACTObjective: The aim of this study was to evaluate heavy metals (Cr, Fe, Ni, Cu, Zn, As, Cd, Hg, Pb) and selenium levels in digestive gland and gill tissues of wild Mediterranean mussel Mytilus galloprovincialis (Lamarck, 1819) collected from four locations in Izmir Bay. Methods: A total of 180 samples of the wild Mediterranean mussel M. galloprovincialis with shell length of 50-60 mm were collected from four locations. Inductively coupled plasmamass spectroscopy was used to determine heavy metals and selenium concentrations in mussel samples after microwave digestion process. March 5, 2015] and the effects of these plants on ecosystem of the Izmir bay have been monitored [15,18].
Results
ICP-MS as a technique for the inorganic trace analysisshows an excellent sensitivity for a large numbers of elements of interest and the speed of measurement makes it suitable for routine, multielement determinations at trace and ultratrace levels. Important characteristic is the ability to detect and measure concentrations of analyzed elements at very low levels [19,20].The aim of this study was to quantify and compare heavy metals and selenium in digestive glands and gill tissues of M. galloprovincialis collected from four locations in Izmir Bay.
Material and MethodsIzmir Bay is located in the eastern Aegean Sea between latitudes of 38°20' and 38°42' N and longitudes of 29°25' -27°10' E. It is one of the largest natural bays of the Mediterranean. Izmir which is the third largest city in Turkey is located at the west part of the Anatolian peninsula and it is an important industrial and commercial center and a cultural focal point. The Izmir Bay has been considered dividing into three areas as Outer, Middle and Inner Bay according to their physical characteristics. The main industries in the region include food processing, oil, soap and paint production, chemical industries, paper and pulp factories, textile industries and metal processing [21][22][23].
