摘要
Sixteen leafy and non-leafy edible vegetables were collected from the Northern Al-gour area, Jordan, and analyzed for Pb and Cd using atomic absorption spectrometry. In addition, soil samples were collected from areas adjacent to the sites from which the vegetables samples were collected and about 40 m from the road. Results indicated that the average Pb and Cd concentrations in the selected edible vegetables were found in the following order: Leaves roots fruits seeds. Moreover, Pb and Cd levels in soil samples collected from the near main road were higher than those soil samples collected from the sites 40 meters far from the main road.
