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.

Anahtar Kelimeler

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

Öz

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.
