The oil of hazelnuts collected in 2022 (S1) and 2023 (S2) from a garden in the Piraziz district of Giresun Province was extracted and analyzed to measure the levels of 16 polycyclic aromatic hydrocarbons (PAHs). The highest total concentration of polycyclic aromatic hydrocarbons (Σ16PAHs) was 8.483 ± 0.032 ng/kg in sample S1 and 6.075 ± 0.024 ng/kg in sample S2. The value of naphthalene, the most abundant PAH analyte, is higher than that of the other analytes. The total amount of PAHs indicates that 92.35% of sample S1 and 87.82% of sample S2 are naphthalene. Notably, benzo[a]pyrene (BaP), a known carcinogen, was not detected in either sample. The analysis of variance technique was employed to investigate the differences between the mean values of the oils. The results demonstrated that there were significant differences between the mean values.

Depolama Sonrası Fındık Yağlarındaki Polisiklik Aromatik Hidrokarbon (PAHs) Düzeylerindeki Değişimlerin Belirlenmesi

Öz

Giresun İli Piraziz İlçesindeki bir bahçeden 2022 (S1) ve 2023 (S2) yıllarında toplanan fındıkların yağı çıkarılmış ve 16 polisiklik aromatik hidrokarbon (PAH) düzeylerini ölçmek için analiz edilmiştir. Polisiklik aromatik hidrokarbonların (Σ16PAH) en yüksek toplam konsantrasyonu S1 örneğinde 8,483 ± 0,032 ng/kg ve S2 örneğinde 6,075 ± 0,024 ng/kg olarak bulunmuştur. En bol bulunan PAH analiti olan naftalinin değeri diğer analitlerden daha yüksektir. Toplam PAH miktarı, S1 örneğinin %92,35'inin ve S2 örneğinin %87,82'sinin naftalin olduğunu göstermektedir. Bilinen bir kanserojen olan benzo[a]piren (BaP) her iki örnekte de tespit edilmemiştir. Yağların ortalama değerleri arasındaki farkları araştırmak için varyans analizi tekniği kullanıldı. Sonuçlar ortalama değerler arasında önemli farklar olduğunu gösterdi.
