Gıda Maddesi Olarak Sıkça Kullanılan Kimyon ve Tarçın Aromatik Bitkilerindeki Bazı Toksik Element (Cr, Cd, Cu ve Pb) Seviyelerinin Belirlenmesi

Aromatik bitkiler önemli olumlu veya olumsuz sağlık etkileri olan geniş bir konsantrasyon aralığında çeşitli elementlerin depolarıdır. Yirmiden fazla element insanlarda ve diğer memelilerde bilinen fizyolojik aktivitelere sahiptir. Kobalt, bakır, krom ve nikel gibi elementler biyolojik yapıların temel bileşenleridir, ancak işlevleri için gerekli sınırların üstündeki konsantrasyonlarda toksik olabilmektedirler. Arsenik, kurşun ve kadmiyum gibi diğer elementlerin çeşitli biyokimyasal reaksiyonlarda iyi bilinen toksik rolleri vardır. Eser elementlerin tayini için kullanılan birçok metod bulunmaktadır. Bu çalışmada kimyon ve tarçın örneklerindeki bazı toksik elementlerin miktarları belirlenmiştir. Toplam 8 örnekte Cr, Cd, Cu ve Pb element miktarları alevli atomik absorpsiyon spektrometresi (FAAS) metodu ile belirlenmiştir. Bulunan sonuçlara göre çalışılan örneklerde Cr elementi yapılan çalışmalara göre yüksek bulunmuştur. Cu, Pb ve Cd elementlerinin normal seviyelerde olduğu tespit edilmiştir. Ayrıca analitik yöntem doğrusallık, tespit limitleri, doğruluk ve geri kazanım deneyleri ile doğrulanmış, her durumda tatmin edici değerler elde edilmiştir.

Determination of Some Toxic Element (Cr, Cd, Cu and Pb) Levels in Cumin and Cinnamon Aromatic Plants Frequently Used as Foodstuff

Aromatic plants are repositories of various elements in a wide concentration range with significant negative or positive health effects. It is known that there are more than twenty elements with physiological activity in mammals and humans. Elements like copper, nickel, cobalt and chromium are necessary ingredients of biological structures. Such elements may be toxic at concentrations above the limit values required for their function. In many biochemical reactions, elements such as lead, cadmium and arsenic have toxic effects. In this study, the amounts of some toxic elements in cumin and cinnamon samples were determined. Elemental amounts of Cr, Cd, Cu and Pb in 8 samples were analyzed with flame atomic absorption spectrometry (FAAS) method. According to the results, Cr element was found to be higher in the studied samples. Cu, Pb and Cd elements were found to be normal. In addition, the analytic method was confirmed by detection limits, accuracy, linearity and recovery experiments, sufficient values were obtained in each case.
