Abstract

The levels of trace elements in food and agricultural samples have been shown to influence human and plant metabolism. The study of heavy metal speciation is of interest for the evaluation of their mobility, bioavailability and ecotoxicity. In this study, the zinc concentrations of the cereal and soil samples were determined using flame atomic absorption spectrometry (FAAS). The soil samples related to the cereal were digested and extracted using different digestion and extraction reagents. The results indicate that the soil samples collected from various locations, contain varying amounts of the metal, and it was distributed between Residual, Oxide, and Carbonate fractions. The results of the study also showed that the lowest value of total Zn concentration in soil was in sampling points KC1 (1.49 mg/kg) and the highest value was in the sampling points KK5 (207.2 mg/kg) and MD5 (207.2 mg/kg). It was found out that in all the sampling locations, the Zn concentration is within the tolerable range (10 – 300 mg/kg). The relationship between the cereal Zn and soil-extractable Zn concentrations was significant (P < 0.05).
