Oil spillage in the Niger Delta region of Nigeria and its associated hazard is on the increase and there is urgent need to combat its increasing volume by predicting the volume in the future thus, the objective of this study is on the prediction of the volume of oil spill in Nigeria via the Stochastic Markov Model. Two States Markov analysis were employed and it was discovered that the volume of oil spill incident were mostly maintained in a high state than in a low state and the predicted values were approximately steady at a probability value of 0.519 which is in favour of the high state. The study concluded that for the Nigerian Federal government to combat the volume of oil spill, she should in addition to enforcing the laws governing the volume of oil spill incident, employ remediation process that would help clean up the mess caused the spillage

Infrastructure development is the hub of economic diversification, for any nation to grow economically; it must be seriously dependent on its iron and steel development. The construction of the Ajaokuta iron and steel industry can be dated and traced to the year 1979 and as of 1994, the project was near completion with 98% of the project almost completed. As of 2018, the project is yet to be completed. The gap between 1979 through 1994 to 2018 gives the Nation a whole cause to worry thereby implying whether the delay in the work is due to the incompetency of the contractors in question or is it due to bad governance and suspected looting. This paper, therefore, applies the use of the popular Critical Path Method (CPM) in monitoring the progress of the yet-to-be-completed Ajaokuta project focusing on its possible network diagram, earliest and latest time of completion.

Heavy metals naturally are non-biodegradable constituents of the earth’s crust that accumulate and persist indefinitely in the ecosystem as a result of both human and natural activities. Their contamination of vegetables remains an issue of public health interest due to the frequency, and quantity of consumption. The over exposure to these heavy metals continues to pose serious health threat globally. This study was aimed to assess the heavy metal contents of staple vegetables [Telfairia occidentalis, Amaranthus hybridus and Ocimum gratissimum] within Enugu metropolis; the leaves were screened for heavy metals [Arsenic As, Lead Pb, Cadmium Cd, Nickel Ni, Chromium Cr and Cobalt Co], by atomic absorption spectroscopy (AAS). Results (Mean±SD,  mgkg-1 ) showed that Amaranthus hybridus: contained [Pb-0.109±0.350, Cr -0.161±0.004]; Ocimum gratissimum: [Ni-0.179±0.028, Cd-0.033±0.006, Cr-0.176±0.036], and Telfairia occidentalis: [Pb-0.153±0.139, Co-0.198±0.148]; of which some values were slightly above WHO/FAO standards. Although, the estimated daily intakes (EDIs) were below referenced tolerable daily intakes (TDIs). The hazard quotients (HQs) were below 1 (HQ<1), but As and Cd, were exceptions; while the hazard index (HI) values were all above 1 (HI>1). The slightly above standard references of some of these heavy metals, and HI>1 values in this study are a concern, as potential health risks may arise amidst the population over a period of time, therefore, there is need to eliminate the likely sources of the latent contamination.
