Determination of Heavy Metal Contamination in Soil and Accumulation in Cassava (Manihot Esculenta) in Automobile Waste Dumpsite at Ohiya Mechanic Village

Abstract: Human health challenges resulting from consumption of food contaminated by heavy metals necessitated the investigation of soil and cassava plants around automobile waste dumpsite at Ohiya mechanic village, Abia State, Nigeria. Soil and cassava samples collected randomly at the site were analyzed for cadmium (Cd), copper (Cu), lead (Pb) and chromium (Cr). The values of highest concentration of Cu and Pb in soil was recorded in 0-10 cm, Cr was obtained in 21-30 cm while Cd was in 11-20 cm soil depth. The concent… Show more

“…The concentrations of Cr and Pb in soil at the fecal sludge dumpsite were 2.40±0.40 to 21.03±1.43 and 0.09±0.02 to 0.35±0.03 mg/kg, respectively. The values of Cr (2.40±0.40 to 21.03±1.43 mg/kg) is well below the accepted limit of 100 mg/kg (Cr) as described by Dutch criteria for soil (Ogbonna et al, 2020a), the 100 mg/kg (Cr) established by Codex Alimentarius Commission (FAO/WHO, 2001), the 100 mg/kg (Cr) set by National Environmental Standards and Regulations Enforcement Agency, NESREA of Nigeria (NESREA, 2011), 50 mg/kg (Cr) set by Ministry of Agriculture, Fisheries and Food, MAFF (MAFF, 1992) and 50 mg/kg (Cr) set by the European Commission, EC (EC, 1986). The concentration of Cr (21.03±1.43 mg/kg) at 1 m is 2.09, 3.51, 8.76 and 2,103 times higher than its values at 5 m, 15 m, 30 m from the fecal sludge dumpsite and control, respectively.…”

The values of Cr (2.40±0.40 to 21.03±1.43 mg/kg) is well below the accepted limit of 100 mg/kg (Cr) as described by Dutch criteria for soil (Ogbonna et al, 2020a), the 100 mg/kg (Cr) established by Codex Alimentarius Commission (FAO/WHO, 2001), the 100 mg/kg (Cr) set by National Environmental Standards and Regulations Enforcement Agency, NESREA of Nigeria (NESREA, 2011), 50 mg/kg (Cr) set by Ministry of Agriculture, Fisheries and Food, MAFF (MAFF, 1992) and 50 mg/kg (Cr) set by the European Commission, EC (EC, 1986).

“…The concentration of Pb in soil at the fecal sludge dumpsite was 0.09±0.02 to 0.35±0.03 mg/kg, which is well below 164 mg/kg (Pb) set by National Environmental Standards and Regulations Enforcement Agency, NESREA (NESREA, 2011) of Nigeria, the accepted limit of 85 mg/kg (Pb) described by Dutch criteria for soil (Ogbonna et al, 2020a) and the maximum permitted level of 50 mg/kg (Pb) established by Codex Alimentarius Commission (FAO/WHO, 2001) (Table 6). The concentration of Pb (0.35±0.03 mg/kg) at 1 m is 1.25, 2.19, 3.89 and 35 times higher than its values at 5 m, 15 m, 30 m from the fecal sludge dumpsite and control, respectively.…”
