“…However, the cadmium content 10.00 mg kg À1 (Iyaro), 29.00 mg kg À1 (Siluko), and 7.30 mg kg À1 (West Circular) obtained in the study rendered the sites unsuitable for agricultural and residential application. The highest concentration of 244.50 mg kg À1 (Iyaro), 344.00 mg kg À1 (Siluko), and 228.00 mg kg À1 of manganese was found at the three sites, respectively (Ukpebor and Unuigbe 2003). Rushton (2003) reported incidence of low-birth-weight births among people living near landfill sites.…”

“…Both the sites contain high heavy metals and may enter into a food chain that can lead to health hazards at both the sampling sites Karim et al (2014). The concentrations of heavy metals in top oil samples collected from three refuse dump sites by atomic absorption spectrophotometry were determined by Ukpebor and Unuigbe (2003). A low level of heavy metal concentration was reported for commercial and industrial application, and therefore, can be utilized for these purposes.…”

This article reviews the impact of biomedical waste on water, soil, air quality, the environment, and human health. Hospitals and nursing homes generate increasing amount of biomedical waste in an unscientific manner. As such, poor waste management practices by these institutions cause exposure to health hazards and actual environmental problems. The issue of biomedical waste identification, handling, and disposal needs to have a heightened review so that better management practices and protocols can be established.

“…The occurrence of heavy metals in municipal waste dumpsites in various parts of Nigeria and other developing countries has been reported (Aluko and Oluwade 2003;Anikwe and Nwobodo 2002;Ukpebor and Unuigbe 2003;Odai et al 2008). For instance, Ukpebor and Unuigbe (2003) reported elevated levels of heavy metals in dumpsite soils as compared to soil samples taken 50 m from the dumpsite in Benin city, Nigeria.…”

“…For instance, Ukpebor and Unuigbe (2003) reported elevated levels of heavy metals in dumpsite soils as compared to soil samples taken 50 m from the dumpsite in Benin city, Nigeria. A report by Anikwe and Nwobodo (2002) indicated that heavy metals (Pb, Cu, Fe and Zn) increased between 214 and 2040 % in the soils of the dumpsite vis-a-vis soils from non-dumpsite in Abakaliki, Nigeria.…”

The study assessed the levels of some heavy metals in soils in the vicinity of a municipal solid waste dumpsite with a view to providing information on the extent of contamination, ecological risk of metals in the soils and human health risk to the residents in Uyo. Soil samples were collected in rainy and dry seasons and analyzed for metals (Pb, Cd, Zn, Mn, Cr, Ni and Fe) using atomic absorption spectrometry. The concentrations of heavy metals (mg/kg) at the dumpsite in rainy season were Pb (9.90), Zn (137), Ni (12.56), Cr (3.60), Cd (9.05) and Mn (94.00), while in dry season, the concentrations were Pb (11.80), Zn (146), Ni (11.82), Cr (4.05), Cd (12.20) and Mn (91.20). The concentrations of metals in the studied sites were higher than that of the control site (P < 0.05). Pollution indices studies revealed that soil samples from dumpsite and distances from 10 and 20 m east of the dumpsite were highly polluted with cadmium. Ecological risk assessment carried out showed that cadmium contributed 98-99 % of the total potentially ecological risk. No probable health risk was observed as the total hazard index of all the metals was less than one. However, children were found to be more susceptible to heavy metal contamination than adult.

“…Table 1 show that the metallic levels of the mining site soil were higher in both seasons than the level in the control farm. However anomalies in metallic levels could occur as a result of heavy metal deposition on soil surface from various sources through atmospheric transportation (Ukpebor and Unuigbe, 2003). The studied metals had no specific patterns of distribution during both seasons.…”

The removal of large quantities of overburden through mining has resulted in the pollution of various ecosystems. Soil pollution around the Itakpe mine in Kogi State, Nigeria was studied through the determination of heavy metal concentration and chemical speciation of the metals cadmium (Cd), copper (Cu), magnesium (Mg), nickel (Ni), lead (Pb) and zinc (Zn) in soil using Flame Atomic Absorption Spectroscopy. Soil digestion was done with hydrofluoric-perchloric (HF-HClO 4) acid mixture (5:1) and sequential extraction was carried out with different reagents in the extraction steps; Exchangeable, bound to carbonates, bound to Fe-Mn oxides, bound to organic matter and residual. Mean metal content of mining site soil is 0.16±0.02, 0.15±0.03, 0.04±0.02, 0.11±0.02, 0.07±0.01 and 0.04±0.03 g/g for Cd, Cu, Mg, Ni, Pb and Zn, respectively. Results of sequential extraction of the mining site soil show that the highest metallic levels were observed in the Fe-Mn, organic and residual fractions.
