Türkiye’nin Karadeniz Bölgesi’ndeki Balık Pazarlarından Seçilmiş Balık Türlerindeki Ağır Metallerin Değerlendirilmesi

Bu çalışma, Türkiye'nin doğu Karadeniz sahillerindeki ndeki balık pazarlarından satın alınan Sarda sarda, Trachurus trachurus, Merlangius merlangus, Mullus barbatus, Sardina pilchardis, Thunus thynnus Belone belone, Engraulis encrasicolus, Scomber scomber gibi çeşitli balık türlerinin kas dokularındaki ağır metal kirleticileri inceledi. Bu şekilde bulunan kirleticiler arasında kobalt (Co): 0.01-0.16, manganez (Mn) 0.11-4.41, krom (Cr): 0.51-2.30, kadmiyum (Cd): 0.08-0.10, bakır (Cu): 0.26-1.18, kurşun (Pb): 0.10-0.57, nikel (Ni): 1.07-24.0 ve çinko (Zn): 5.46-16.9 ppm. Bu toksin seviyeleri, insan tüketimi için güvenli kabul edilen günlük ve haftalık alım yönergeleriyle karşılaştırıldığında, nikel dışında, belirtilen seviyelerin altında olduğu görülmüştür. Bir istasyondan bir türde bulunan normalin üzerindeki nikel seviyeleri haricinde şu anda insan sağlığı için hiçbir tehlike olmadığı sonucuna varılabilir.

Assessment of Heavy Metals in Selected Fish Species from Markets in the Black Sea Region of Turkey

The present study examined the heavy metal contaminants in the muscle tissues of various species of fish including Sarda sarda, Trachurus trachurus, Merlangius merlangus, Mullus barbatus, Sardina pilchardis, Thunus thynnus Belone belone, Engraulis encrasicolus, Scomber scomber purchased from fish markets across Turkey’s Eastern Black Sea region. The contaminants thus found included cobalt (Co): 0.01-0.16, manganese (Mn) 0.11-4.41, chromium (Cr): 0.51-2.30, cadmium (Cd): 0.08-0.10, copper (Cu): 0.26-1.18, lead (Pb): 0.10-0.57, nickel (Ni): 1.07-24.0, and zinc (Zn): 5.46-16.9 ppm. These toxin levels were compared with daily and weekly intake guidelines deemed safe for human consumption, and what was found was that these values were all below outlined levels with the exception of nickel. What can be concluded this that there currently is no hazard to human health with the exception of above normal nickel levels, as found in one species from one station.
