“…The mean of the heavy metal levels from the three communities is shown in This results indicates high level of contamination and higher than values from the control site aze-azaga in Ndoni area of Ogba/Egbema/Ndoni LGA of Rivers State. These values were lower than works by Fosu-mensah et al, [12] Pb (184.44 mg/kg), Cd (103.66 mg/kg), Cu (202.99 mg/kg) and Ni (72.00 mg/kg), but higher than reports by Farid et al, [13] Cd (0.00-0.111ppm), Pb (0.87-8.97pmm) and Ni (0.017-1.72 ppm). The mean from the three study communities were high.…”

The study was to identify the source and evaluate the health risk of heavy metals in contaminated agricultural soil from Egi community (Oboburu, Obagi and Ogbogu), Niger Delta, Nigeria. Multivariate and health risk equations were employed to achieve this. The mean of heavy metals in samples of Oboburu indicated high levels for Fe (271.0±156.6 mg/kg), Pb (111.2±94.97 mg/kg), and Mn (27.92±23.80 mg/kg), Obagi was high for Fe (248.4±175.9 mg/kg), Mn (80.46±12.40 mg/kg), and Co (116.3±193.7 mg/kg), and Ogbogu was high for Fe (160.9±150.3 mg/kg), Co (240.1±412.1 mg/kg), and Mn (42.90±16.82 mg/kg) respectively. Geo-accumulation index indicated that Pb, Cd and Co was of high contamination and the enrichment factor showed that metals were of anthropogenic sources. The Principle component analysis revealed three (3) components accounting for 88.448%, which revealed that the contamination in the sample was more of anthropogenic than biogenic. The Cancer Risk estimate for children population was of high risk for Ni, Cr, Cd and Pb (10-5 to 10-6) while adult population was 10-6 and lower. The non-carcinogenic risk indicated highest value for children in Co (2.75), Pb (1.70E-1) and Fe (1.32E-1), while adult in Co (1.007) and Fe (3.29E-2). The findings suggest human activities have contributed greatly to the contamination of the agricultural soil and usage of such may be of risk to the users.

“…Similarly, Lago-Vila et al [45] on analysis of quarry site soil stated a higher Cr level 1300 µg/g in a studied soil. Fosu-Mensah et al [46] on the contrary established a lower chromium level 56.0±1.15 µg/g in soils and vegetation of Korle lagoon. Sexana [27] observes that soils contamination could be attributed to the parent materials of the soils.…”

The soil samples from Mambila Plateau were analyzed to determine the physicochemical properties of elements present by energy dispersive X-Ray Fluorescence. The physical and chemical parameters determined were colour, pH, electrical conductivity, specific gravity and elemental identifications of Cr 2 O 3 , CuO, NiO and V 2 O 5 respectively. The pH values for soils of the study area are high between 3.96-4.30 being acidic, electrical conductivity values ranged from 81.79 -238 mS/cm with higher electrical conductivity value at N 1 having 238 mS/cm and lower electrical conductivity at S 1 81.79 uS/cm respectively. The soil are yellow, red and gray; with hue steps of 2.5YR, 5YR, 7.5YR, and 10YR, a step values between 3-7 and the chroma range of 1-6. The specific gravity which also is the relative density range from 2.00-2.50. The percentage elemental contents identified for trace elements decreased in the order V 2 O 5 > Cr 2 O 3 >NiO > CuO. The highest percentage concentration of element found was V 2 O 5 at N 4 0.29% while, CuO showed minimum concentration of 0.01%. The entire soils indicated high acidity levels due to the pH results tested, with spatial variation of the elements oxides contents higher at

“…The concentration of Zn from soil samples from the present area of study was higher than the Zn concentration reported by Ibe et al [16] in abandoned municipal waste dumpsites in Owerri, Imo State, Nigeria, which gave a concentration of 1.07 mg/kg. Fosu-Mensah et al [36] also reported a lower Zn concentration (2.05 mg/kg) from reclaimed waste dumpsites at Korle Lagoon area in Accra, Ghana. The mean Ni concentration (34.78 mg/kg) from a waste disposal site in Ibadan, Nigeria as described by Auta and Morenikeji [37] and that reported by Ofudje et al [38] from Lagos, Nigeria gave Ni concentration of 64.17 mg/kg.…”

This study was carried out to investigate heavy metals concentrations: lead (Pb), cobalt (Co), cadmium (Cd), zinc (Zn), nickel (Ni), copper (Cu) and manganese (Mn) in Musa paradisiaca (plantain), Zea mays (maize), Cucumeropsis manii (melon), Manihot esculenta (cassava) and soil samples from dumpsites in Onne, Eleme Local Government Area, Rivers State, Nigeria. The plant leaf and soil samples were measured for heavy metals concentrations using atomic absorption spectrophotometer. The health risk index (HRI) of the heavy metals following the consumption of these plant materials by the populace was estimated using standard protocols. The heavy metals concentrations in the leaf samples ranged from 0.012-14.712 mg/kg, whereas those of the soil samples were within the range of 2.543-16.459 mg/kg. Cd concentrations in the soil and leaf samples were above the maximum permissible level according to the World Health Organization (WHO). The bioaccumulation of the heavy metals followed the trend: (M. paradisiaca) Zn > Pb > Co > Mn > Cu > Cd > Ni; (Z. mays) Mn > Pb > Co > Zn > Cu > Cd > Ni; (C. mannii) Mn > Co > Pb > Cu > Zn > Cd > Ni; (M. esculenta) Zn > Pb > Mn > Cu > Co > Ni > Cd. The highest bioaccumulation of the heavy metals occurred in M. esculenta. The estimated HRI of Pb in M. esculenta was greater than 1. HRI > 1 was indicative that the consumer population is not safe. Cassava-based meals from the dumpsites contained Pb at toxic level, whereas Co, Cd, Zn, Ni, Cu, and Mn concentrations in plantain-, maize-and melon-based meals were relatively within safe limits.
