Thesis Abstract

Abstract
Outdoor air pollution is a significant environmental health risk globally, with substantial impacts on human health. In Nigeria, a rapidly urbanizing country with industrial growth and increasing vehicular traffic, outdoor air pollution has become a major public health concern. This review aims to summarize the current knowledge on the health impacts of outdoor air pollution in Nigeria and identify future research needs to address this growing issue. Studies have shown that outdoor air pollution in Nigeria is characterized by high levels of particulate matter (PM), nitrogen dioxide (NO2), sulfur dioxide (SO2), and volatile organic compounds (VOCs) emanating from various sources such as vehicular emissions, industrial activities, biomass burning, and dust from unpaved roads. These pollutants have been linked to a range of adverse health outcomes, including respiratory diseases, cardiovascular diseases, and even premature death. Vulnerable populations such as children, the elderly, and individuals with pre-existing health conditions are particularly at risk. Despite the growing body of research on outdoor air pollution in Nigeria, there are still several knowledge gaps that need to be addressed. First, there is a need for more comprehensive air quality monitoring across different regions of the country to better understand the spatial and temporal variations in pollution levels. Additionally, studies focusing on the specific sources and chemical composition of air pollutants in different urban and rural settings are essential for developing targeted interventions. Furthermore, research on the long-term health effects of chronic exposure to outdoor air pollution in Nigeria is limited, highlighting the need for longitudinal studies to assess the cumulative impacts on population health. Interventions such as promoting clean energy sources, improving public transportation systems, and implementing stricter emission standards are crucial for mitigating the health impacts of outdoor air pollution in Nigeria. In conclusion, outdoor air pollution poses a significant health threat in Nigeria, with diverse sources contributing to poor air quality and associated health risks. Addressing the current knowledge gaps through targeted research efforts will be essential for developing effective policies and interventions to protect public health and mitigate the impacts of outdoor air pollution in the country.
