ABSTRACT

This study evaluated the levels ofPAHs and heavy metals in some vegetables (Tallinium triangulae and Piper guinesse) that was purchased within the city ofAba. The quantification ofthe PAHs and heavy metals (Zn, Cu, Al, Co, Cd, V, Mn. Fe. Cu, and Cr) concentration were done using a Gas Chromatography and an Atomic Absorption Spectrometry respectively. The vegetables from the highway markets in Aba gave (mg kg'1) 4.57, 1.98, 1.84, 154.57, 2.60 and 4.55 respectively while the control gave 1.84mg/kg and 1.42 mg/kg. The concentration of tire heavy metals in the sample follows the decreasing order as follows V > Fe > Al > Mn > Co > Cr > Pb > Cd. The concentration ofVanadium were higher in all the samples and Cadmium was the least metal found in the samples. All selected samples collected from the urban markets contained significant increase in PAHs and heavy metals. However, to prevent any chronic health risk and extent of heavy metals contamination, steps must be taken to reduce human activities that increases the levels of heavy metals and PAHs at the urban markets. Regular monitoring of heavy metals in vegetables grown in waste water irrigated areas is also ofparamount important.
