This study was conducted in Buner district of Pakistan to investigate the presence of Cadmium (Cd) and Lead (Pb) in roadside soil and Brassica rapa (Shalgham). For that purpose, soil and B. rapa samples were collected from primary, secondary, tertiary roadside fields and control site. The samples were investigated for Cd and Pb presence via atomic absorption spectrometer (PerkinElmer, AAS-PEA-700). The Cd concentrations in soil ranged from 2.55 to 4.35 with mean value 3.31 mg/kg, 3 to 8.85 with mean value 5.41 mg/kg, 3.15 to 5.55 with mean value 4.9 mg/kg and 2.45 to 5.25 with mean value 3.93 mg/kg on primary, secondary, tertiary road and control site respectively. While the Pb concentration in soil was 0.85 to 40.85 with mean value 22.83 mg/kg, 13.25 to 35.3 with mean value 22.05 mg/kg, 29.83 to 43.42 with mean value 34.36 mg/kg and 1 to 36.1 with mean value 21.61 mg/kg on primary, secondary, tertiary road and control sites, respectively. In B. rapa the Cd concentrations ranged from 2.13 to 3.5 with mean value 2.87 mg/kg, 2 to 6 with mean value 3.6 mg/kg, 2 to 3.7 with mean value 2.8 mg/kg, 1.5 to 2.6 with mean value 2.21 mg/kg for primary, secondary, tertiary roads and control site respectively. While the Pb concentration in B. rapa ranged from 2.9 to 7.3 with mean value 5.12 mg/kg, 0.83 to 11 with mean value4.25 mg/kg, 0.33 to 5.3 with mean value 4.27 mg/kg, 0.2 to 11 with mean value 6.08 mg/kg for primary, secondary, tertiary roads and control site respectively. By applying Two-way ANOVA significant variation at P≤ 0.05 was found among the concentration of Cd and Pb in B. rapa and soil samples collected from various sample points. It was concluded that the B. rapa along different roads sides were found contaminated with Pb and Cd which may pose health risk.
