The hypotheses formulated here are, that the indicators of environmental health hazards and housing development as measured by the number of houses are not significant in the slums of Abuja, that the spread of health devastating diseases and ramshackle developed houses are not significant in the slum areas and that the Environmental Health Hazards does not differ significantly among the slum areas. Secondary source of data collection such as written source materials and primary source of data collection, which include participant observation, questionnaire, oral interview and laboratory work, were employed to collect data. The sample size number was firstly determined using Yaro Yamani formula. Yaro Yamani formula is donated as: n = population/ 1+population (significance level)2. This gave 400 questionnaires. But four-hundred questionnaires were just 0.75% of the total estimated average household. In other to get a sample size that represents at least two percent of the total estimated average household size, it was done by finding two percent of an estimated average household size in each of the slums. So, 1067 questionnaire that amount to two percent of the total estimated average household were randomly distributed to the dwellers of ten sampled slum areas of Abuja and 652 were retrieved. After the analyses, the Principal Component Analysis produce factor scores of environmental health hazards and housing development from different slums, which shows that the indicators of environmental health hazards in the form of dirty drains and open waste dumps increase with houses and house hold numbers. The PCA further produce factor score of the occurrence of health devastating diseases and ramshackle developed houses in the slums of Abuja, which shows that health devastating diseases increase with high number of ramshackle developed houses. Also the result of one way ANOVA conducted shows that the calculated F Value for all the heavy metals in the soil are less than the Critical F Value of 4.76 at 3and 6 degree of freedom with confident level of 0.05 The analysis also shows that the calculated significant level is above 99% in all the variables, meaning that the rate of environmental health hazards in form of heavy metal concentrations in the soil does not differ significantly among the slums. These findings show that the indicator of environmental hazards does not affect the rate of housing development in the various

Research Goals and Themes
The research aims to conduct a scholarly assessment of environmental health hazards and housing development in the slum areas of Abuja, Nigeria, in order to identify the causal links between uncontrolled urban expansion and the deterioration of public health, and to propose data-driven recommendations for sustainable improvement.
- Identification of slum dwellers' activities impacting the human environment.
- Analysis of environmental health indicators (pollution, waste disposal, water quality).
- Statistical correlation between housing quality (ramshackle structures) and disease prevalence.
- Assessment of slum upgrading strategies and institutional capacity.
- Examination of heavy metal concentrations in soil as an environmental hazard.
Excerpt from the Book
1.1 BACKGROUND OF STUDY
According to Sule (2004), one serious problem of over urbanization and environmental quality had been revealed by the index and chronic housing deficit to provide adequate accommodation for it’s over populated dwellers. Shortage of housing accommodation has become an enduring feature of the urbanization process generally on the globe and cities of the developing countries in particular. The earth, our spaceship is a habitat for 7 billion people with over one billion people around the world living in slums. Going by these anomalies, it is estimated that by 2030 the world’s slum population could rise to two billion if no action is taken. (United Nation Center for human settlement – UNIHABITAT, 2011). For the poor, this environmental challenge seems to pose no problem to them, this is because urban areas have, and will continue to provide a means of improving quality of life, as well as being in close proximity to better jobs and income more than the rural settings. Deteriorating condition for those who live a rural life style and the promise of a better life have prompted million of rural inhabitant the world over to migrate to the nearby cities. This development has given rise to one of the

Frequently Asked Questions
What is the core focus of this research?
The work primarily focuses on evaluating the nexus between environmental health hazards and the development of substandard housing within the slum settlements of Abuja, Nigeria.
What are the primary themes addressed?
The study centers on urbanization dynamics, housing quality, sanitation challenges, soil contamination, and the prevalence of water-borne and respiratory diseases among low-income urban dwellers.
What is the central research objective?
The main objective is to empirically assess the effect of environmental hazards on housing development, to identify differences in hazard distribution among various slums, and to suggest policy solutions.
Which scientific methodologies were employed?
The study utilizes a mixed-methods approach, including participant observation, household questionnaires, statistical analysis (PCA and ANOVA), and laboratory testing of soil and water samples.
What is examined in the core chapters?
The study moves from theoretical frameworks of urban growth to a detailed empirical analysis of specific slum areas, focusing on data presentation, laboratory results, and hypothesis validation.
What key terms define the work?
The research is defined by concepts such as slum emergence, urban primacy, environmental impact, bioaccumulation of heavy metals, and sustainable slum upgrading strategies.
How does this study contribute to environmental policy?
It provides empirical evidence that rapid, uncontrolled housing expansion is the primary driver of environmental degradation in Abuja, helping policymakers identify where intervention is most urgent.
What were the major findings regarding soil quality?
Laboratory analysis indicated that open dump sites in these slums are highly contaminated with heavy metals like lead, cadmium, and arsenic, which pose long-term neurotoxic and carcinogenic risks to the residents.
