Vegetables contamination by heavy metals and associated health risk to the population in Koka area of central Ethiopia.

ABSTRACT: Contaminated soil and vegetables have continued to instigate threat to human health globally and specially in developing countries. This study was aimed to determine concentrations of certain heavy metals in soil and vegetables (cabbage and tomato) from Koka area of central Ethiopia using Inductively Coupled Plasma Optical Emission Spectrophotometer (ICP-OES). The amounts of As, Pb, Cd, Zn, Cu, Hg and Co detected in soil samples were found to surpass the reference values for agricultural soil. Similarly, the concentrations of As, Pb, Cd, Cr and Hg obtained in both tomato and cabbage samples have exceeded the recommended values with the mean levels generally ranging from 0.93-6.76, 1.80-7.26, 0.33-1.03, 0.86-5.16 and 3.23-4.36 mg/kg dry weight, respectively. The result obtained have signifi
