Besin ağının üst basamağında yer alan kuşlar, çevresel kirleticilerden en fazla etkilenen canlı gruplarıdır. Bu çalışmada Van Gölü havzasını üreme ve beslenme amacıyla kullanan Van Gölü Martısındaki (Larus armenicus) bazı ağır metal birikimleri araştırıldı. Besin ağının en üst basamağında yer alan kuşların toksik maddeleri hangi oranlarda biriktirdiği ve nasıl etkilendiklerini tespit etmek amacı ile beslenme oranları da dikkate alınarak yetişkin ve yavru martılarının vücut tüylerinden ve beslendiği ortamlardaki sulardan örnekler alındı. Metal konsantrasyonları ICAP 6000 spektrofotometresi ile ölçüldü. Alınan örneklerde; Demir (Fe), Kadmiyum (Cd), Bakır (Cu), Kurşun (Pb) ve Arsenik (As) konsantrasyonlarına bakıldı. Analiz sonuçlarına göre; Cu (6.43 mg kg-1), Pb (4.02 mg kg-1) ve Cd (0.14 mg kg-1) konsantrasyonlarının en fazla yavrularda, Fe konsantrasyonun (94.32 mg kg-1) ise en fazla erginlerde olduğu görüldü. Dünya Sağlık Örgütü (WHO) ve TSE-266 standartlarına göre; Su içerisindeki As, Fe, Cd, Cu ve Pb konsantrasyonlarının içilebilir referans değerinden çok fazla olduğu tespit edildi. Yavru ve yetişkinlerdeki konsantrasyon farklılıklarının beslenme yoğunluğuna bağlı olarak değiştiği görülmektedir.

Detection of Heavy Metal Concentrations in Feathers of Armenian Gull (Larus armenicus Buturlin, 1934) in Van Lake Basin/TÜRKİYE

Öz

Birds are the living groups at the top of the food web and most affected by environmental pollutants. The aim of the present study was to detect levels of some heavy metal accumulations in the Armenian Gull (Larus armenicus), which uses the Van Lake basin for breeding and feeding purposes. Samples were taken from the body feathers of adult and juvenile gulls and from the waters in their feeding environments, taking into account the feeding rates, in order to determine at what rate the birds at the top of the food web accumulate toxic substances and how they are affected. In the samples taken, Iron (Fe), Cadmium (Cd), Copper (Cu), Lead (Pb) and Arsenic (As) concentrations were measured. Metal concentrations were measured using ICAP 6000 Spectrometer. According to the results of the analysis, Cu (6.43 mg kg-1), Pb (4.02 mg kg-1) and Cd (0.14 mg kg-1) concentrations were highest in juveniles, while Fe concentration (94.32 mg kg-1) was found to be highest in adults. Compared with WHO (World Health Organization) and TSE-266 standart; As, Fe, Cd, Cu and Pb concentrations in water were higher than the permissible levels for drinking water. Concentration differences in Juveniles and adults seem to vary depending on the feeding density.
