Assessment of heavy metals (Cadmium and Lead) in vacuum packaged smoked fis species (Mackerel, Salmo salar and Oncorhynhus mykiss) marketed in Ankara (Turkey)

Ankara’daki marketlerde vakum paketli dumanlanmış balık türlerinde (Mackerel, Salmo salar ve Oncorhynhus mykiss) ağır metallerin (kadmiyum ve kurşun) belirlenmesi. Ankara’daki marketlerde, ticari olarak satılan dumanlanmış ve vakum paketlenmiş balık türlerindeki kadmiyum (Cd) ve kurşun (Pb) konsantrasyonları değerlendirilmiştir. 2004-2005 yılları arasında Ankara’daki hipermarketlerden toplam 73 adet dumanlanıp paketlenmiş balık fileto örneği temin edilmiştir. İz element konsantrasyonu GFAAS yöntemi ile ölçülmüştür. Cd için sınır değer kuru maddede 0.003-0.034 mg kg -1 olarak bulunurken, Pb için bu değer 0.001-0.791 mg kg-1 olarak bulunmuştur. Analiz edilen tüm balık örneklerinde kadmiyum konsantrasyonu, Türkiye ve Avrupa Birliği Mevzuatı tarafından 0.05 mg kg-1 olarak belirlenen limitlerin altındayken, 27 balık örneğindeki Pb seviyesi Türkiye’deki kabul edilebilir limitleri aşmıştır (0.2 mg kg-1). Buna rağmen, yüksek seviyelerde ölçülen ağır metal konsantrasyonlarında bile, haftada 400 g balık tüketen 60 kg ağırlığında bir yetişkinin tahmini haftalık Pb ve Cd alım miktarı, Joint FAO/WHO Expert Committee tarafından tavsiye edilen geçici tolere edilebilir haftalık alım miktarının (Cd için 7 μg-kg-1 ve Pb için 25 μg kg-1) altında olduğu saptanmıştır.

Ankara'daki marketlerde vakum paketli dumanlanmış balık türlerinde (Mackeral, Salmo salar ve Oncorhynhus mykiss) ağır metallerin (kadmiyum ve kurşun) belirlenmesi

Cadmium (Cd) and lead (Pb) concentrations in vacuum packaged smoked fish species that are commercially sold on the Ankara market were evaluated. A total of 73 smoked fish fillet samples were purchased from Ankara hypermarkets between 2004- 2005. Trace metal concentrations were measured by GFAAS. The range found for Cd 0.003-0.036 mg kg-1 dry weight, while that for Pb was 0.001-0.791 mg kg-1 dry weight. Cadmium concentrations in all fish species analyzed (100%) were below 0.05 mg kg-1 the limit specified by Turkish and EU legislation, whereas Pb levels in 27 fish samples (36.9%) exceeded the Turkish acceptable limit of 0.2 mg kg-1. However, at even the highest heavy metal concentrations measured, the estimated weekly intakes of Cd and Pb for a 60 kg adult consuming 400 g of fish per week would be below the provisional tolerable weekly intakes recommended by the Joint FAO/WHO Expert Committee of 7 μg-kg-1 body weight for Cd and 25 μg kg-1 body weight for Pb.
