Effect Of Automobile Emission On The Concentration Of Pb And Cd In Soils And Cassava Plant (Manoic Esculenta Crantz) Along Enugu- Port Harcourt Expressway:- Ekwueme, Philip O.
ABSTRACT
The effect of automobile emission
on the concentration of Pb and Cd in soils and various cassava plant parts
along Enugu - · Port Harcourt expressway in Nigeria, was studied. Surface soil
(0 - 30cm) and cassava samples were obtained from sites (Ubakala I, Okigwe I,
and Ishiagu I) close to the expressway location and those far from the I I J
expressway otherwise called remote village location (Ubakala II, Okigwe II and
lshiagu II). The phyiso-chemicals properties of the soils, and Pb and Cd levels
in both the soil and plant samples were determined. The sand fraction was the
predominant particle size in all the soils both at the expressway and the
remote village locations. The mean sand content in these soils was 63.8 while
the mean silt and clay content were 14.3 and 21.2 respectively. The soil pH
ranged from 5.6 to 5.9. The exchangeable Ca in the soils ranged from 2.00 to
2.80 with a mean value of 2.8. The effective cation exchange capacity of the
soils were low and ranged from 4.13cmol/kg to 8.63cmol/kg. Soils of the
expressway location had mean Pb content of 56.25mg/kg which was significantly
(P< 0.05) higher than the mean value of 37.49mg/kg obtained for remote
village locations. However, significant site x location interaction was also
obtained. There was no significant difference between the mean Cd levels of
0.03mg/kg and O. 14mg/kg obtained for expressway and remote village soils
respectively. Positive and significant correlation coefficient was obtained
between Cd in the soils and Effective cation exchange capacity of the soils.
Cassava samples from expressway location had higher mean Pb and Cd levels in
the leaves than those of the remote village locations. No significant
difference was obtained between the Pb and Cd levels in Cassava pulp and '\
peel in the two locations (Expressway and remote village) studied.
