Nergiz -Şamat: Assessment of heavy metal concentration in feathers of Armenian Gull (Larus armenicus Buturlin, 1934) and water samples of Hazar Lake, Turkey -10221 -APPLIED ECOLOGY AND ENVIRONMENTAL RESEARCH 17(4):10221-10227. Abstract. Accumulation levels of heavy metals in the feathers of birds reflect the abundance of these pollutants in the medium and birds can be useful indicators of this kind of pollution. The aim of the present study was to detected levels of some heavy metals of
... y metals of juvenile and adult Armenian Gull (Larus armenicus) and in the surface water of Hazar Lake, Turkey. The feather samples from different parts of the bodies of dead adult and juvenile Armenian Gulls were collected. Water samples were taken from different sampling stations distributed across the lake. Heavy metal concentrations were measured using a Thermo Scientific ICAP 600 Spectrometer. There was no significant statistical difference for bioaccumulation of heavy metals and trace elemets in adult and juvenile gull feathers (p>0.05). However, the highest metal concentrations were measured in juveniles. The highest average residue amounts in juvenile cover feathers were 0.02 mg/kg Cd, 0.46 mg/kg Pb, 0.72 mg/kg Cu, 58,31 mg/kg Fe, 0.04 mg/kg Ni, 8.38 mg/kg Zn, 0.07 mg/kg Se, 1.3 mg/kg Mn, 0.005 mg/kg Cr and 0. 01 mg/kg As. Mean values of all metals were within the acceptable limits of normal values for waterbirds, except Pb and Mn. When we evaluated the findings heavy metal concentration of the water were detected decrease in sequence of; Fe>As>Zn>Ni>Cd>Cu>Cr>Pb>Mn>Se. Compared with WHO (World Health Organization) and TSE-266 (Turkish Standarts Institution) standards; Cd, Cu, Zn and Cr concentrations in water were higher than the permissible levels for drinking water. It seems Armenian Gull feathers are useful monitoring tool for assessing heavy metal contamination.
