The concentration of lead in three citrus varieties and soil from orchards in Benue State was analyzed using atomic absorption spectrophotometer (AAS). The result of the analysis revealed the concentrations of lead in Washington (21353 µg/kg), Ibadan Sweet (65437 µg/kg), Valencia (62740 µg/kg) and the concentration of lead in soil (708600 µg/kg) respectively. The levels of Pb reported in the three citrus varieties are above the WHO/FAO permissible limits in citrus fruits (100 µg/kg) in all the samples analyzed. The values of Pb detected in the soils analyzed are below the WHO/FAO (90000 µg/kg) limits of Pb in agricultural soils.

Keywords: Soil; Lead; Atomic Absorption Spectrophotometer; Ibadan Sweet; Valencia.
