Assessment of Air Quality Parameters in Selected Road Intersections in Port Harcourt, Nigeria: A Case Study of their Potential Impacts on Terrestrial and Aquatic Environment (Published)
Selected air quality parameters (SO2, NO2, CO, PM2.5 and PM10) concentrations were measured at selected road intersections within the study area. SO2, NO2, CO, PM2.5 and PM10 were found to be above permissible limits of Federal Ministry of Environment (FME) and WHO, while CO was within the limit at all sampling stations. The result of the statistical analysis showed that the P-value was less than 0.05 (level of significance) in PM2.5 and PM10 parameters, which imply that these air quality parameters were significantly different from the FME limits. Similarly, NO2 and SO2 results showed significant differences when compared with FME standards. Generally, the results showed that the concentration the assessed pollutants were significantly higher than the recommended Nigeria FME limits. Thus, they constitute potential sources of health hazards to humans and aquatic flora and fauna within the water bodies in the study area. Routine monitoring of these air quality parameters and advocacy on their impacts on terrestrial and aquatic environment cum organisms amongst others, were recommended as a way of reducing air pollution within the study area.

Environmental Quality of Enugu, Nigeria As Impacted by the Primary Air Pollutants in the Area (Published)
Air pollution activities have increased over the years in urban areas of most developing countries like Nigeria. The same has been experienced in Enugu metropolis. This study therefore examined how environmental quality of Enugu metropolis has been impacted by the polluted air in the environment. The metropolis was classified into different neigbourhoods and then stratified into low, medium and high density areas. Samples were randomly collected from these neighborhoods. In determining the residential environmental quality of the area factor analysis (principal component analysis was used to reduce the various environmental quality variables into single factor known as “Y” variable. This served as dependent variable. Primary air pollutants; particular matter, Nitrogen dioxide, sulfur dioxide and carbon monoxide constituted the independent variables as x1, x2, x3 and x4 respectively. Using multiple regression model a relationship between the dependent and independent variable was established. The coefficient of determination in the result showed that adjusted r2=.917, indicating that 91.7% variation in the residential environmental quality could be predicted from air pollution. Health challenges of reduced oxygen carrying capacity of blood, chronic bronchitis and worsening respiratory illnesses were identified as some of the effects. Also identified, are acidification of soils, staining of fabrics among others on the environment. Making petroleum products like kerosene available and affordable to all by the federal government of Nigeria, among others have been recommended.

Survey of the Quality Physical, Chemical and Bacteriological of the Underground Waters of the Continental Terminal of the Township of Abomey-Calavi (Benin) (Published)
Campaigns of withdrawal of the underground waters have been done during the year 2013 to the level of the boring situated in the township of Abomey-Calavi, to control their quality. These withdrawals were the object of analysis according to the techniques of assessment of water quality described by Rodier (1978) and to the recommendations of the world organization of health (WHO). The physical and chemical analysis showed that 98.7% of the studied boring present some concentrations superior to the norms recommended by the WHO (1994) and by Benin (2011). The studied boring present without exception a bacteriological pollution. The very elevated microbial germ presence in water could constitute a sanitary risk importing for the inhabitants who consume the water of these boring.
