Abstract

This study aimed to assess the concentration of fourteen elements (Al, Ag, As, Cd, Co, Cr, Cu, Fe, Hg, Ni, Pb, Se, V, Zn) in 91 edible freshwater fish muscle samples using inductively coupled plasma-mass spectrometry (ICP-MS). Statistical analyses such as principal component, cluster, and correlation analysis were done to evaluate the obtained data. The order of mean concentrations (mg/kg wet wt.) of metals in all fish meat samples were Al (204) > Zn (10.2) > Fe (6.43) > Cu (0.666) > Hg (0.589) > Ni (0.556) > Pb (0.497) > Cr (0.396) > Ag (0.291) >Se (0.144) > As (0.074) > Co (0.043) > Cd (0.037) >V (0.027). Hg, Ca, and Pb concentrations in some samples exceeded the permissible legal limits, whereas As was lower than maximum allowable limits. Ninety-one fish samples were categorized into five categories by PCA with Eigenvalues higher than 1.00. Cluster analysis results showed that the pollution with metal pairs analyzed might be from similar sources. In conclusion, as the long-term effect of low concentrations of heavy metals caused serious health problems ranging from carcinogenic effects to immunological disorders, heavy metal content in fish and fishery products must be closely monitored to protect consumer health.

Türkiye'de Perakende Satışı Yapılan Tatlı Su Balık Türlerinde Ağır Metallerin Birikimi: Toksik Metallerin Potansiyel Halk Sağlığı Tehlikesi

Abstract

Bu çalışmada, Inductively Coupled Plasma–Mass Spectrometer (ICP-MS) cihazı kullanılarak 91 yenilebilir tatlı su balığı kas örneğinde 14 elementin (Al, Ag, As, Cd, Co, Cr, Cu, Fe, Hg, Ni, Pb, Se, V, Zn) konsantrasyonunun değerlendirilmesi amaçladı. Elde edilen verileri değerlendirmek için temel bileşen, küme ve korelasyon analizi gibi istatistiksel analizler yapılmıştır. Tüm metallerin numunelerdeki konsantrasyonları (mg/kg yaş ağırlık) sırasıyla; Al (204) > Zn (10.2) > Fe (6.43) > Cu (0.666) > Hg (0.589) > Ni (0.556) > Pb (0.497) > Cr (0.396) > Ag (0.291) >Se (0.144) > As (0.074) > Co (0.043) > Cd (0.037) >V (0.027) idi. Bazı numunelerdeki Hg, Ca ve Pb konsantrasyonları yasal limitleri aşarken, As izin verilen maksimum limitlerin altındaydı. Doksan bir balık örneği PCA'ya göre Özdeğerleri 1.00'den yüksek olan beş kategoriye ayrıldı. Küme analizi sonuçları, analiz edilen metal çiftleri ile kirliliğin benzer kaynaklardan olabileceğini göstermiştir. Sonuç olarak, düşük konsantrasyonlardaki ağır metallerin uzun vadeli etkisi kanserojen etkilerden immünolojik bozukluklara kadar uzanan ciddi sağlık sorunlarına neden olduğundan, tüketici sağlığının korunması için balık ve su ürünlerinde ağır metal içeriği yakından izlenmelidir.
