Linking Air Quality Index with Biomarkers of Exposure in Urban Populations

Abstract

Ethan Mitchell*

Air quality has become a critical public health concern in urban environments, where pollution levels can reach hazardous thresholds due to factors such as industrial emissions, vehicular traffic, and construction activities. The Air Quality Index (AQI) serves as a vital tool for communicating the quality of air in a given area, providing real-time data on pollutants such as particulate matter (PM), nitrogen dioxide (NO?), sulfur dioxide (SO?), and ozone (O?).
