“…al., 2015). The result of this study revealed that the soils were more of sand, followed by silt and least in clay as earlier reported by Onweremadu and Duruigbo (2007). Hence, the high sand content encouraged leaching of heavy metals deep down into the soil depth due to the larger pore size (Akpoveta et.…”

Cassava mill effluent has become a major cause of environmental degradation which affects soil properties. This study revealed the impact of cassava mill effluent on microbial diversity, physicochemical parameters and heavy metal concentrations in the receiving soils collected in triplicate between April and June, 2015 from five sites in Ogwa, Edo State, Nigeria. Standard methods were used for the soil analysis. The mean heterotrophic, coliform Zn > Mn > Cr > Ni > V > Cd > Pb . The cassava mill effluent negatively affected the soil microbial diversity, physicochemical parameters and heavy metal concentrations in the impacted soils.

“…Soils suffer from pollution (Onweremadu and Duruigbo, 2007) such as crude oil spillage. Crude oil which is abundantly located in the Niger-Delta region of Nigeria is spilled on soils due to several factors such as pipeline destruction (Nwilo and Badejo, 2001).…”

ABSTRACT:The study investigated zinc availability in relation to selected soil properties in a crude-oil-polluted Eutric Tropofluvent in Egbema, Southeastern Nigeria. For this purpose, three treatments have been applied: unpolluted soil, polluted without vegetation and polluted with vegetation with five replicates arranged in a randomized complete block design. Guided by transect sampling technique, soil sampling was carried out in June 2008. Soil samples were collected from the three different land units using soil auger at a depth of 0-20 cm. Standard laboratory procedures were adopted in analysing the soils. Soil generated data were subjected to analysis of variance and correlation analysis. Results showed highly significant variation (p = 0.01) in bulk density, porosity, silt: clay ratio, pH, effective cation exchange capacity, percent base saturation, total nitrogen, organic matter, available phosphorus, calcium: magnesium ratio and zinc. It was found that zinc was higher in crude oil polluted soils than in non-polluted soil and it was below critical limits. Zinc availability in relation to selected soil properties in the crude oil polluted soils indicated that clay and organic matter did not affect zinc availability, while pH and effective cation exchange capacity did. A study on zinc dynamics in crude-oil-polluted soils will certainly provide further information on the management of crude-oil-polluted soils since it is one of the key micronutrient for crop productivity.

“…Existence of easily soluble Cd compounds in plant tissues indicates the importance of sap in Cd studies (Roosens et al, 2003). Onweremadu and Duruigbo (2007) reported that Cd is considered one of the most important environmental pollutants in agricultural soils because of the potential harmful effects it may have on food quality Abstract: Conspicuous vegetation entities of pedogenic soils rich in cadmium and their diethylene triamine pentaacetic acid (DTPA)-extractable Cd content (DCd) under the temperate continental and Mediterranean climatic conditions of western Anatolia were determined. Foliage of herbaceous plants and nearby soil samples was collected from 51 zinc mining areas.…”
