Trachurus mediterraneus ponticus Aleev'deki Metal Seviyeleri, 1956 ve Tüketiciler İçin Sağlık Riski Değerlendirmesi

Bu araştırmada, Trachurus mediterraneus ponticus türünün kaslarındaki Cd, Hg, Pb, As, Al, Cu, Fe ve Zn düzeylerini belirlemek amaçlanmıştır. Karadeniz'in Samsun kıyılarından 2021 ve 2022 yılları Eylül ve Aralık ayları arasında toplanan balık örnekleri İndüktif Eşleşmiş Plazma Kütle Spektrofotometresi kullanılarak analiz edilmiştir. İstavritin kas dokularındaki metal değerleri izin verilen değerlerin altında bulunmuştur. Zn daha yüksek ortalama konsantrasyona sahip olarak bulunmuş (5.475 mg/kg yaş ağırlık (y.a.), bunu Fe (ortalama konsantrasyon 3.887 mg/kg y.a) ve Cu (ortalama konsantrasyon 0.178 mg/kg ya) izlemiştir. Cd en düşük konsantrasyon (0.0077 mg/kg y.a.) olarak bulunmuş, bunu Hg (0.0096 mg/kg y.a.), Pb (0.0453 mg/kg y.a.) ve Al (0.1077 mg/kg y.a.) izlemiştir. Metaller için tek tek hedef tehlike katsayıları (THQ'lar) ve toplam hedef tehlike katsayıları (TTHQ'lar) <1 olarak bulundu ve bebekler, çocuklar ve yetişkinler tarafından tüketilmesi için sağlık riski olmadığını göstermektedir. Pb için risk indeksleri (RI'ler) 2022'de yetişkinler için 1.93x10-7 2021'de bebekler için 5.75x10-7 olarak önemsiz kanserojen risklerini gösterirken, As için RI'lar 2022'de yetişkinler için 8.61x10-5'ten 2021'de bebekler için 2.29x10-4’a olarak tolere edilebilir veya kabul edilebilir kanserojen risklerini göstermektedir.

Metal Levels in Trachurus mediterraneus ponticus Aleev, 1956 and Their Health Risk Appraisal For Consumers

This research was carried out to determine the levels of Cd, Hg, Pb, As, Al, Cu, Fe and Zn in the muscles of Trachurus mediterraneus ponticus. The fish samples were collected from the Samsun coasts of the Black Sea between September and December in both 2021 and 2022 and were analysed by using Inductively Coupled Plasma Mass Spectrophotometer. The metal values in the muscle tissues of horse mackerel were below the permissible values. Zn has the higher mean concentration (5.475 mg/kg wet weight (w.w.)) followed by Fe (mean concentration of 3.887 mg/kg w.w.) and Cu (mean concentration of 0.178 mg/kg w.w.) The Cd was found at the lowest (0.0077 mg/kg w.w.) mean concentration followed by Hg (0.0096 mg/kg w.w.), Pb (0.0453 mg/kg w.w.), and Al (0. 1077 mg/kg w.w.). The target hazard quotients (THQs) for individual metals and the total target hazard quotients (TTHQs) were <1 in horse mackerel indicating no health risk for consumption by infants, children, and adults. The risk indexes (RIs) for Pb were from 1.93x10-7 for adults in 2022 to 5.75x10-7 for infants in 2021, indicating their insignificant carcinogenic risks, whereas for As RIs were from 8.61x10-5 for adults in 2022 to 2.29x10-4 for infants in 2021, indicating their tolerable or acceptable carcinogenic risks.
