The identification of chemical forms of lead in agricultural samples is of interest for the evaluation
of its mobility, bioavailability and ecotoxicity. In this study, the lead concentrations of the guinea corn and soil
samples were determined using Flame Atomic Absorption Spectrometry (FAAS). The soil samples related to
the guinea corn were digested and extracted using different digestion and extraction reagents. The results
indicated that the soil samples collected from various locations, contain varying amounts of metal and was
distributed between residual, oxide and carbonate fractions. The result of the study also showed that in all the
samples locations, the Pb contain in the soil was below the tolerable limit of 200 mg/kg and the ANOVA (p
= 0.002<0.05) indicated a significant difference in the Pb concentrations across the various guinea corn
samples. Similarly, the ANOVA (p = 0.040<0.05) also indicated a significant difference in the Pb
concentrations across the various guinea corn grown soils.
Key words: Chemical forms, flame atomic absorption spectrometry, guinea corn, lead, soil, ,
