Heavy metal levels in the black sea anchovy (Engraulis encrasicolus) as biomonitor and potential risk of human health

Çalışmada 2013 yılı avcılık sezonunda güney Karadenizin Türkiye ve Gürcistan kıyılarından toplanan en önemli ticari deniz balığı Engraulis encrasicolus türünün kas dokusunda ağır metallerden arsenik, bakır, çinko, cıva, kadmiyum ve kurşun konsantrasyonları tahmin edilmiştir. Hamsinin yenilebilir dokusunda Cu, Hg, Cd ve Pb tespit edilememiştir. Hamside biriken çinko yağ miktarı ile negatif korelasyon gösterirken arsenik birikiminin yağ miktarı ile herhangi bir etkisi gözlenmemiştir. Zn ve As miktarları sırasıyla 8.6 -13 ve 0.41 -0.69 mg/kg arasında bulunmuştur. Hamsi örneklerindeki As ve Zn konsantrasyonları ulusal ve uluslararası yönergelerce verilen tolerans düzeylerinden daha yüksek değerlerde bulunmamıştır. Yenilebilir dokulardaki hiçbir değer standart yönetmeliklerde belirtilen değerleri aşmamış ve tüketiciler için hiçbir sağlık tehlikesi oluşturmamıştır.

Biyomonitör olarak Karadeniz Hamsisinin (Engraulis encrasicolus) ağır metal düzeyleri ve insan sağlığına potansiyel riski

The concentrations of heavy metals arsenic, copper, zinc, mercury, cadmium and lead were estimated in muscle tissue of commercially the most important marine fish Engra ulis encrasicolus collected from the south coast of the Black Sea, Turkey and Georgia during fish season in 2013. Cu, Hg, Cd and Pb were not detected in the edible part of anchovy. Zinc shows negative correlation with fat content while no effect of fat con tent was observed for arsenic accumulation in anchovy. The ranges of Zn and As concentrations were found between 8.6 -13 and 0.41 -0.69 mg/kg, respectively. Concentrations of As and Zn in the anchovy samples were not elevated the tolerance levels of national and international guidelines. None of the values in edible tissues exceeded the standard guideline values and would pose no health hazards for consumers.
