【 摘 要 】

The Bioconcentration factor (BCF) of selected heavy metals in grassesgrowing along High Density Traffic Area (HDTA) and Low Density Traffic Area (LDTA) ofPort Harcourt metropolis was ascertained. The results show BCF for Heavy Metals ingrasses along HDTA are significantly higher than their counterpart along LDTA eventhough the values of heavy metals in the soil along the LDTA are relatively higher than thosealong HDTA. This shows that aerial deposition or diffusion of these Heavy Metals fromautomobile exhaust and adsorption processes to the grasses along HDTA plays a major rolein their Bioconcentration. The order of BCF of Heavy Metals in grasses along HDTA (Cr >Cd = Co > Ni > Zn > Pb > Fe) and LDTA (Cr > Cd > Ni > Pb > Co > Zn > Fe) shows thatCr and Cd having highest BCF of 2.97 and 2.50 in grasses along HDTA and 0.68 and 0.67in grasses along LDTA respectively, could be used to monitor their aerial deposition fromautomobile exhaust.
