An appraisal of Heavy Metal Concentration in Soil and Selected Subterranean Animals in Olusosun Landfill, Ojota, Lagos State (Published)
As a result of the global industrial activities, contamination of the ecosystem by heavy metals has given rise to one of the most important ecological and organismic challenges. An experimental study was performed to ascertain the levels of heavy metals in soil and selected subterranean animals in dumpsites in Lagos State. One (1) kg each of four composite soil samples at a depth of 0 -15cm from the soil surface within the landfill were collected using an auger. The level of parameters such as soil pH, temperature and soil moisture content were determined. Earthworm, Maggot and Spider from each sampled soil were washed in distill water to remove soil particles. The heavy metals (Zn, Cd, Cr, Cu and Pb) were then analyzed by Atomic Absorption Spectrophotometry (AAS). The result of the study showed that Pb and Cd had higher mean concentration (0.75mg/kg and 0.1mg/kg respectively) for the landfill soil sample compared to the control soil sample and subterranean animals. The result also showed that Maggot and Earthworm had higher means concentration of Zn (0.31mg/kg and 0.14mg/kg respectively) compared to the soil samples (landfill and control) and spider. The result was not statistically significant comparing the mean concentration of heavy metals on the landfill soil and the subterranean animals. Chromium (Cr) was not detected in the study. The study concluded that there is high anthropogenic influence and persistence of the heavy metals which accumulated in the environment and pose serious ecological and health challenges.

State Police and Police- Operational Efficiency: Footing For Strengthening National Security In Nigeria: – A Scrutiny of Ojo in Lagos State (Published)
The current insecurity in Nigeria which includes widespread killings, kidnappings, cultism and police brutality justifies the agitation for creation of state police in Nigeria. Hence, this paper assessed the creation of state police and police operational efficiency as footing for strengthening national security in Nigeria. The study applied theoretical and quantitative methods; information was sourced secondarily through content analysis of textbooks, journals and newspaper. The quantitative data was obtained through administration of 250 questionnaires to the residents of Ojo Local Government by applying simple random sampling and convince techniques. Findings showed that 66 %( 165) of the respondents were male while 34% (85) of the respondents were female, 79%(198) of the respondents strongly agreed that state police will resolve insecurity in Nigeria while 15%(37), strongly disagreed that creation of state police will resolve insecurity in Nigeria however 6%(15) of the respondents were neutral. The paper recommends creation of state police with strict judicial control and deployment of smart security technologies. This study will be of immense benefits to government at various levels, NGOs, the Nigeria Police Force and the researchers in the field of security and public administration.
Challenges of transportation in Obàléndé area of Lagos Nigeria can only be felt and experienced by its ever increasing commuters and the numerous vehicles plying the road facility. Though the status quo of transportation in that area cannot be outrightly written off, the prospect of keeping in view possible transport infrastructures into the transport system and executing it at the adequate locations in the said area is a feat that is worth researching into. This research looks into the actual transportation challenges faced by Nigerians in Obàléndé area of Lagos, with every possible conceivable solutions that is practical. The data gathered for this research will be via literature review and structured interview. The interviews will be conducted using purposive sampling methods and the data analysis will be done using coding and content analysis. From the information obtained it is recommended
Impact of Illiterate Rural Migrant Workers on the Effectiveness of Construction Safety Induction in Lagos State Nigeria (Published)
Demand for housing, factory buildings and other social infrastructural development in the major urban cites around the world are ever on the increase. To meet the high demand of labour force required, contractors often employ illiterate rural migrant workers that drift from rural areas to cities for greener pasture. These categories of construction site workers have poor understanding of English and therefore contribute to a disproportionate number of site fatalities and injuries on sites. This study aimed at investigating the extent to which these illiterate rural migrant construction site workers impact on the effectiveness of construction safety induction training on sites. The study examines the demographic data of the illiterate rural migrant construction site workers, construction H&S legislation and language used in conducting site safety induction training to the workers. Questionnaire survey was then structured from literature and administered to workers with the aid of interpreters. This was followed by interviews conducted with site supervisors. Data was electronically manipulated using MS Excel. From the analysis, the study revealed that about 64.5% of the general workers are rural migrant workers with no basic education and trade qualifications. The study further revealed that poor understanding of spoken English among the rural migrant workers contribute to site injuries and fatalities. Nevertheless, there is lack of commitment on the part of contracting organizations, particularly among the medium and small sized companies in conducting safety induction training to workers. The study concludes that H&S is an important issue in the Occupational Safety and Health Act (OSHA) all over the World. The Act emphasizes the importance of employee education pertaining to H&S of the work environment regardless of whether the employee is educated or illiterate. The study therefore recommends that contractors conduct site H&S induction training to workers whether they are temporary or permanent; and that safety induction training should be conducted in local language of the rural migrant workers.
Property Conversion, Its Impact on Residential Areas of Metropolitan Lagos (Review Completed - Accepted)
In most urban centres like Lagos, conversion of Residential structures for pressing commercial needs ‘seems to have become the norm. Residential properties always get built because of the sustained demand which guarantees good return. Once trends begin to suggest that there are higher returns to gain from commercial property they begin to convert existing buildings especially when it is difficult to get suitably located land and the cost of building is high. Given the above scenario it becomes relatively cheaper to convert existing residential structures to other uses, more so since existing residential areas have the added advantage of being in the city center with access to existing services such as electricity, water supply, telephone and transportation. Such locations also offer advantages of proximity to require labour and markets. The market forces when aggressively pursued as a major determinant in property development in the urban centres as a result of either bad planning or weak planning management tend to obviate the ‘public good” that is inherent in good planning. Worse still is a situation where such a force is allowed to invade the “Planned Residential Areas (PRA) which are both symbol and model for urban life and development. The paper tries to turn away from the theoretical background and assumptions, associated with market enforces in real estate to highlight the consequences associated with conversion. It is Pertinent to mention that policy decisions at any level are not to be seen as immutable for flexibility is the keynote of successful property management (Ratcliffe,1978).
