“…The concentration of Cu (22.14 mg/kg) reported in this study is lower than 47.0 mg/kg reported by Fisseha et al (2008) [22]; 61 mg/kg by Ndiokwere (1984) [23]; 27 mg/kg by Ward et al (1977[24]); 29.7 mg/kg by Jaradat and Momani (1999) [25]; it is however higher than 2.78 mg/kg reported by Bai et al (2008) [26]. The bioavailable component of Cu in study area (48.19%) is lower than 6-72% and 0.4-74.4% reported by Nastja, R. S. (2011) [3]; Lena and Gade (1997) [4] respectively, while the value is higher than 16% and 3-30% reported by Yobouet et al (2010) [5] and Erika-Andrea et al (2005)27] respectively.…”

Abstract:The concentrations of trace elements (Cu, Zn, Cr, Pb and Cd) 22.14, 25.06, 12.41, 14.13 and 9.11 respectively while in control area soil Cu, Zn, Cr, Pb and Cd had concentrations (mg/kg) of 19.69, 22.79, 7.09, 13.53 and 1.24 respectively. The bioavailable components (obtained from exchangeable, water and acid-soluble, and reducible phases) of Cu, Zn, Cr, Pb and Cd were 48.19%, 47.61%, 37.87%, 43.52% and 50.71% of their total concentrations respectively in study area soil while in control area 40.49%, 45.37%, 64.03%, 36.07% and 45.02% were obtained for Cu, Zn, Cr, Pb and Cd respectively. Levels of the trace elements in soils of both study area and control area were observed to be within European Union safe limits except for Cd in the study area.

“…However the observed levels in the soils were lower than levels found in some roadside soils in Auckland (Ward et al, 1977), and Nigeria (Ndiokwere, 1984). The levels of Pb and Zn in the vegetables analyzed were between those found in vegetables in Kampala (Nabulo, 2004) The samples collected at Ebony had the highest metal concentration probably because of its closeness to the road, about 5-10 m and the very high volume of traffic compared to the other sites, which were further away from the road, 20 -40 m, and also the nearness of the site at Ebony to an automobile mechanical shop.…”

This paper discusses the levels of some heavy metals (Ni, Cu, Pb and Zn) in roadside soils and crops along the Obansandjo way in the Accra metropolis of Ghana. Soil and plant samples were collected from three different sites; Kawukudi (K), Ebony (E), and Dzorwulu (D) all along the Obansandjo way in Accra. The samples taken were preserved and later acid digested and analyzed along side control soil and plant samples using standard analytical methods. The following mean levels of Ni, Zn, Cu and Pb on the roadsides were detected: 228.65 ± 102.98, 35.98 ± 18.39, 24.577 ± 9.04 and 18.25 ± 13.05 (all in mg/kg) respectively. The mean level of Ni was above the critical permissible concentration. Ni, Zn, Cu and Pb in the crops were: 3.343 ± 2.0, 6.97 ± 4.5, 1.909 ± 0.71 and 3.515 ± 1.3 (all in mg/kg) respectively. Ni, Pb, Cu and Zn were detected in both soils and crops. The levels of all the metals except Ni were below the phototoxic levels.

“…Okunola et al (2007), reported the Levels of trace metals in soil and vegetation along major and minor roads in metropolitan city of Kaduna, Nigeria. Ndiokwere (1984), in a study reported heavy metal pollution from vehicle emission and its effect on vegetable and crops in Nigeria while Yekeen (2012) observed moderate and considerable soil pollution by heavy metals in Odo-Oba and Sabo areas respectively in Ogbomosho. However detailed reports for high density traffic areas like Port Harcourt metropolis in particular are unknown.…”
