Purpose: The aim of the study was to assess the impact of urbanization on air quality in European metropolitan areas.
Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries.
Findings: A comprehensive study on the impact of urbanization on air quality in European metropolitan areas reveals significant correlations between urban development and air pollution levels. The research, conducted across various European cities, demonstrates a clear association between the degree of urbanization, characterized by population density, industrial activities, and transportation infrastructure, and the degradation of air quality. High levels of pollutants such as particulate matter (PM), nitrogen oxides (NOx), sulfur dioxide (SO2), and volatile organic compounds (VOCs) are consistently observed in densely populated urban centers, particularly in areas with intense vehicular traffic and industrial emissions.
Implications to Theory, Practice and Policy: Environmental Kuznets curve theory, urban metabolism theory and environmental justice theory may be use to anchor future studies on assessing the impact of urbanization on air quality in European metropolitan areas. Encourage the incorporation of green infrastructure, such as green roofs, urban forests, and permeable surfaces, into urban planning and development practices. Enhance regulatory frameworks by setting stringent air quality standards, implementing emission controls, and enforcing compliance measures for industries, vehicles, and other pollution sources.
