“…Cd > Cr > Pb > As > Hg. (Ozkan, 2012) and (Adaikpoh, 2013) reported similar Igeo values, however, the values obtained for all the metals investigated were lower compared to that reported by (Lodhaya et al, 2017) across all the sites except for Pb. This may be attributed to moderate human activities.…”

“…These values obtained were in a close range to 13.21 -41.93 mg/kg reported by (Mohammed & Folorunsho, 2015) and 6.89 -55.43 mg/kg reported by (Abatyough et al, 2015). However, the results were higher than 1.10 mg/kg reported by (Alibrahim et al, 2017) and 0.02 -1.56 mg/kg reported by Adaikpoh, 2013. The high concentration levels of Cr could be attributed to the proximity of the sites to the source of pollution which includes the presence of business outlets, fueling and service stations.…”

This work examined the concentrations of As, Cd, Cr, Hg and Pb pollution in soil and estimated the potential ecological risks of these metals in Makurdi and its environs, using established pollution indices. The information derived from pollution indices will help to assess the extent, and intensity of anthropogenic contaminant deposition on surface soil in the study area. The soil samples were collected from sixteen (16) locations across the investigated sites, sampled as appropriate and treated using established methods and analyzed using atomic absorption spectrometry (AAS). The findings have revealed that the concentrations of the metals in the topsoil samples were arranged in the sequence from increasing to decreasing order thus: Cr > Pb > Cd > Hg > As. It was observed that the pollution levels of As and Hg were insignificant, while, the level of pollution caused by Cd, Cr and Pb ranged from low level of contamination to high level of contamination across the investigated sites, except, for the control site (BZ) whose pollution level was insignificant with respect to the heavy metals studied. The results could be used as preliminary baseline data for heavy metal concentrations for future assessment and monitoring. Therefore, there is an urgent need to effect mitigation measures to reduce the ecological environmental risks, taking into consideration that human activities which are the main source of pollutants are still ongoing in the study area.

“…In this study, high Pb concentrations of 1692.30 mg/kg at 0-15cm and 1478.11 mg/kg at 15-30 cm were observed to be higher than 86 and 333 mg/kg from Kronum and Amakom dumpsites [13], respectively; 0.40 mg/kg [14]; 262.53 mg/kg [15]; 13.14 mg/kg Pb [16], 219.51 mg/kg [17]; 79.55 mg/kg [9]; 826.13 Pb; [5]; 896 mg/kg [18], 0.41 mg/kg [19], 97 mg/kg [20], 32.47 mg/kg [21] and 102 mg/kg Olayinka et al (2014). However, the Pb concentration was lower than Pb concentrations of 3630 mg/kg [22].…”

The massive influx of electronics into Nigeria has led to environmental challenges due to increase in the production of electronic waste, which causes serious health and pollution problems. This study investigated the level and impact of heavy metals in 30 soil samples from an electronic waste disposal site in southwest Nigeria, using appropriate standard methods. The range concentrations of the heavy metals were 1615 mg/kg Pb, 20 mg/kg Cr, 266.32 mg/kg Ni, 22.39 mg/kg Cd and 242.03 mg/kg Cu at depth 0-15cm while 1453.56 mg/kg Pb, 26.31 mg/kg Cr, 497.11 mg/kg Ni, 17.04 mg/kg Cd and 230.31 mg/kg Cu were observed at depth 15-30 cm. The concentrations of the heavy metals exceeded the allowable limits, except for Cr. The mean degree of contaminations, 18.15 and 14.35, were observed at depths 0-15 and 15-30 cm respectively and indicated considerable and moderate degree of contamination by the heavy metals, respectively. The mean Potential index of 323.52 and 225.79 at depth 0-15 cm and 15-30 cm showed sever toxicity and moderate toxicity, respectively. The I-geo. of Pb at both depths indicated extreme contamination. This study reveals sever potential environmental and health hazards in the neighborhood, ecosystem, and community, and advises that the government should establish a national policy on e-waste and regulate testing of all electronics imported under the names of reuse, donation and recycling, which will halt the importation of e-scraps (e-waste).

“…The soil formation is made up of top reddish clay capping highly porous freshwater bearing, loose pebbly sands and sandstone with local thin clays and shale interbeds which are considered to be of weathered surfaces to white in the deeper fresh surfaces. Limonitic coatings are responsible for the brown reddish-yellowish colour [1,2,22].…”

This paper examined chemical fractionation of selected heavy metals (Cu, Pb, Mn and Ni) in soils around municipal solid waste dumpsites in Benin City, Nigeria, using the multi-step phase-selective extraction schemes for metal speciation. Total concentration levels of the heavy metals were done using atomic absorption spectrophotometry. The results showed that the analysed heavy metals were more abundant in their stabile fractions with the residual fraction dominating the nonbioavailable fractions. The potentially mobile and bioavailable fraction of Cu ranged from 21 to 40%, of Pb ranged from 20 to 30%, of Mn ranged from 16 to 30%, while that of Ni ranged from 18 to 29% in soils around the studied dumpsites. The percentage of bioavailability/mobility of the analysed heavy metals in soils around each studied dumpsite were in the order: dumpsite (I), Pb > Cu > Mn > Ni; dumpsite (II), Cu > Ni > Pb > Mn; and dumpsite (III), Cu > Mn > Pb > Ni. The relative low mobility factors shown by each heavy metal in the studied sites were quite in agreement with the low bioavailable fractions recorded from their fractionation analysis. The overall result shows that large fractions of the analysed heavy metals were in geochemical forms and not readily released into soil solution for bioavailability.
