Soil Profile Quality of a Contaminated Dumpsite in Ibadan, Nigeria
Solid waste disposal may result in soil pollution with implications for groundwater quality. The impact of waste disposal on soil quality of the Aba-Eku dumpsite, Ibadan, Nigeria was studied at five depths in the profile. Soil samples were collected bi-monthly over a 21-month period at three sub-sit...

| description | Solid waste disposal may result in soil pollution with implications for
groundwater quality. The impact of waste disposal on soil quality of
the Aba-Eku dumpsite, Ibadan, Nigeria was studied at five depths in the
profile. Soil samples were collected bi-monthly over a 21-month period
at three sub-sites: - Waste Dump Area (WDA), Leachate Lagoon Area (LLA)
250m down-gradient of WDA; and control (600m away from WDA and LLA);
using an auger and analyzed for various physico-chemical parameters.
Data were analyzed using Principal Component Analysis (PCA) and ANOVA.
Contamination factors were also computed using relevant formulas.
Seven, five and four factors were extracted by PCA, explaining 83%, 86%
and 80% variation in WDA, LLA and control respectively. Positive
loadings for percent gravel (0.941) and permeability (0.596) and
negative loadings from percent sand (-0.912) on the first PC for WDA
suggested increases in the coarse fraction and decreases in the fine
fraction were associated with moderate increases in permeability at the
site. Except iron and potassium, other parameters were significantly
elevated (p |

Cadmium reduced significantly (p<0.05) with depth from
23.7±5.3; (0-15cm) to 12.7±3.0 mg/kg; (75-100cm) suggestive
of gradual leaching into groundwater. Zinc, copper and cadmium had
contamination factors of 56.84, 21.30 and 19.29 respectively in WDA
which reduced to 3.28, 3.71 and 1.09 in LLA down-gradient. Two plants,
Chromoleana odorata and Pennisetum pupureum found between WDA and
LLA sites may have contributed to contaminant reduction and may be
exploited for further remediation of the site.</description><identifier>ISSN: 1119-5096</identifier><language>eng</language><publisher>Ibadan Biomedical Communications Group</publisher><subject>Aba-Eku ; contaminants ; groundwater ; phytoremediation ; Soil ; wastes</subject><ispartof>African journal of biomedical research, 2017-01, Vol.19 (3)</ispartof><rights>Copyright 2016 - African Journal of Biomedical Research</rights><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,780,784,79426</link.rule.ids></links><search><creatorcontrib>Oni, A.A</creatorcontrib><creatorcontrib>Hassan, A.T</creatorcontrib><title>Soil Profile Quality of a Contaminated Dumpsite in Ibadan, Nigeria</title><title>African journal of biomedical research</title><description>Solid waste disposal may result in soil pollution with implications for
