PCDD/F, dl-PCB and indicator PCBs in whiting, horse mackerel and anchovy in Black Sea in Turkey

Karadeniz’den yakalanan ve sıklıkla tüketilen mezgit, istavrit, ve hamsi örnekleri PCDD/F’ler, dioksin benzeri PCB’ler ve indikatör PCB’ler açısından analiz edilmiştir. Sonuçlar PCDD/F-TEQ, dl-PCB-TEQ ve indikatör PCB’ler için sırasıyla 0.28-0.91 pg/g yaş ağırlık, 0.56-1.89 pg/g yaş ağırlık ve 3.05-10.94 ng/g yaş ağırlık olarak bulunmuştur. Balıkların yağ oranları arttıkça, bileşenlerin çoğunun konsantrasyonlarının arttığı gözlenmiştir. Tespit edilen değerler AB “Gıdalarda bulaşanların maksimum seviyelerinin belirlenmesi” mevzuatında belirlenen maksimum kalıntı seviyelerinin altındadır.

Karadeniz’den (Türkiye) yakalanan mezgit, istavrit ve hamsi balıklarında PCDD/F, dl-PCB ve indikatör PCB’ler

Samples of three mainly consumed three edible fish species, whiting, horse mackerel and anchovy, from the Black Sea were analyzed for PCDD/Fs, dioxin-like PCBs and indicator PCBs. The results showed that PCDD/F-TEQ, dl-PCBs-TEQ and indicator PCBs concentrations ranged between 0.28-0.91 pg/g fresh weight product, 0.56-1.89 pg/g fresh weight product and 3.05-10.94 ng/g fresh weight product, respectively. It is observed that with increasing fat content of the fishes most of congeners’ concentrations increased. Measured values were below the maximum residue levels indicated in the EU Commission Regulation “Setting maximum levels for certain contaminants in foodstuffs”.
