    Distribution of cyanide in a cassava-mill-effluent polluted eutric tropofluvent soils of Ohaji Area, South-eastern Nigeria
    (Academic Journals, 2011) Uzoije Atulegwu Patrick; Nnamdi Egwuonwn; Onunkwo-A, Augustine
    This study investigates on the distribution of cyanide on a cassava- mill- effluent polluted eutric tropofluvent soil in Ohaji southern Nigeria. Three morphological land units were marked out namely, the background unit (pedon A), discharged point unit (pedon B) (the effluent receiving unit) and downstream unit (pedon C). Soil sample collection was carried out in five replicates in May 2007 adopting a randomized complete block design techniques. Soil samples were collected from each pedon at different soil profiles: 10 to15, 15 to 30, 30 to 70, 70 to 100 and 100 to 150 cm which were represented as L1, L2, L3, L4 and L5, respectively. Samples of the cassava mill effluent were also collected in five replicates. Standard laboratory methods were adopted for the analysis of both samples. It was observed from the results that cyanide distributed geospatially within the pedons. Furthermore, the results of the soil samples were subjected to correlation and regression analysis between Cn and other soil properties and the analysis showed highly positive significant variation(p = 0.05) in Na, Cd, pH, and clay in both pedons A and B while Pb, sand silt and porosity showed highly negative significance in both pedons. Most soil properties showed non significance in pedon C. Highcoefficients of regression for polynomial functions were recorded in most pedons.

    Evaluation of the effects of industrial wastewater discharge on surface water (A case study of Nigeria breweries Plc Enugu)
    (U. P., 2012-09) Egwuonwu, C. C.; Uzoije, A. P.; Okafor, V. C.; Ezeanya, N. C.; Nwachukwu, M. U.
    The need to undertake an evaluative effect of industrial wastewater discharge on surface water with a case study of Nigerian Breweries Plc Enugu into the Ajali River was borne out of the need to ascertain the level of Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total suspended Solids (TSS) etc and other characterized effluent been discharged into the water body that determines the level of use and quality of this water for irrigation purposes, human consumption and safe ecological habitation of aquatic lives. To achieve this, laboratory analysis was carried out on the Ajali River and the wastewater discharged from the industry and it was confirmed not to have exceeded the benchmark for required discharge of wastewater into streams and rivers as stipulated by some regulatory bodies. In conclusion, treatment measures and regulatory policies were suggested to checkmate the abuse of this water bodies and the danger it might likely pose to aquatic ecological system if regulatory standards were not complied with.
