AB  - The levels of iron (Fe), zinc (Zn), copper (Cu), manganese (Mn), lead (Pb), cadmium (Cd) and  ercury (Hg) content were determined in samples of maize, <I>(Zea may</I>s) guinea corn <I>(Sorghum bicolo</I>r), bambara groundnut <I>(Vigna subterranea</I>n) and cowpea <I>(Vigna unguiculat</I>a) obtained in six different locations along some roads within Nasarawa State, Nigeria by flame atomic absorption spectrophotometery in order to assess the effect of accumulation of the metals of interest on crops as a measure of environmental pollution. The mineral mean value for different locations ranged between: Fe (1.6-18.0, 0.75-7.0; 1.0-29.0 and 2.0-20.0), Zn (2.5-3.1; 2.0-10.2. 0 and 1. 0- 4.0), Cu (0.32-0.42; 0.6-2.0; 1.0-7.0 and 0.48-3.5), Mn (0.03-0.56; 0.31-2.0; 0.5-22 and 0.6-4.5), Pb (0.35-1.35; 1.0-2.1; 1.0-44.0 and 3.2-15.1), Cd (0.15-0.22; 0.15-0.9; 1.0-2.0 and 0.5-1.0) and Hg (not available; 0.1-0.3; 1.0-1.2 and 0.2-1.2) mg/100 g samples of maize, guinea corn, bambara groundnut and cowpea, respectively. The results showed that exhaust gas being released from the automobiles can contribute to the level of lead present in crops and the studied crops can contribute significant amount of cadmium toxicity in diet.
