AYDIN İLİNDE TÜKETİLEN SEBZE VE MEYVELERİN ESER ELEMENT DERİŞİMLERİNİN TAYİNİ

Bu çalışmanın amacı, Aydın’da satılan çeşitli meyve ve sebzelerde kadmiyum (Cd), kobalt (Co), bakır (Cu), krom (Cr), demir (Fe), kurşun (Pb), mangan (Mn), nikel (Ni) ve çinko (Zn) derişimini değerlendirmektir. Bu eser elementler indüktif eşleşmiş plazma optik emisyon spektrometrisi (ICP OES) ile tayin edildi. İncelenen elementlerin derişim aralığı, kadmiyum, kobalt, bakır, krom, demir, kurşun, mangan, nikel ve çinko için sırasıyla 0-0.27 µg/g, 0–0.40 µg/g, 3.23–25.05 µg/g, 0–0.33 µg/g, 7.35–554.86 µg/g, 0–2.19 µg/g, 0–58.34 µg/g, 1.03–16.84 µg/g, 4.02–48.55 µg/g’dır. Metodun doğruluğu standart referans madde (liyofilize edilmiş esmer ekmek-BCR 191) kullanılarak tayin edildi. Bulunan değerler sertifikalı referans değerler ile uyumludur.

DETERMINATION OF TRACE ELEMENT CONCENTRATIONS OF VEGETABLES AND FRUITS CONSUMED IN AYDIN PROVINCE

The aim of this study was to assess the concentration of cadmium (Cd), cobalt (Co), copper (Cu), chromium (Cr), iron (Fe), lead (Pb), manganese (Mn), nickel (Ni) and zinc (Zn) in various fruits and vegetables sold in Aydın. These trace elements were determined by inductively coupled plasma optic emission spectrometry (ICP OES). The concentration range of the investigated elements were 0-0.27 µg/g, 0–0.40 µg/g, 3.23–25.05 µg/g, 0–0.33 µg/g, 7.35–554.86 µg/g, 0–2.19 µg/g, 0–58.34 µg/g, 1.03–16.84 µg/g, 4.02–48.55 µg/g for cadmium, cobalt, copper, chromium, iron, lead, manganese, nickel, and zinc, respectively. The accuracy of the method was determined by using of a standard reference material (lyophilised brown bread-BCR 191). The determined values were in agreement with the certified reference values.
