Urban air quality is a pressing concern with far-reaching consequences for public health, the environment, and overall well-being. This review offers an extensive examination of the origins and contributors to deteriorating air quality in urban settings, with a specific focus on pollutants stemming from industrial and vehicular sources. Industrial operations are substantial contributors to urban air pollution, emitting a wide array of harmful substances like particulate matter (PM), volatile organic compounds (VOCs), nitrogen oxides (NOx), sulfur dioxide (SO2), and heavy metals. The paper delves into the various industrial processes responsible for these emissions and explores strategies to mitigate their adverse impacts. In addition to industry, vehicular emissions resulting from the burning of fossil fuels in automobiles play a pivotal role in the decline of urban air quality. This review examines the various pollutants produced by vehicles, including carbon monoxide (CO), hydrocarbons (HC), and greenhouse gases, while also assessing advancements in technology and policy measures aimed at curbing these emissions. In summary, this review emphasizes the pressing necessity for collaborative actions aimed at mitigating industrial and vehicular pollution within urban regions. These efforts are crucial for safeguarding the health and welfare of urban inhabitants and protecting the environment. Additionally, the study underscores the significance of ongoing research and innovation to create sustainable solutions for enhancing air quality in our constantly evolving urban environments.
