Introduction

The Metro-East region of Illinois, comprising cities such as Granite City and East St. Louis, faces significant environmental challenges, particularly concerning air quality and metal pollution. This report will delve into the factors contributing to these issues, focusing on the region's manufacturing economy and traffic patterns. By examining the sources of pollution and their impacts, we can better understand the environmental challenges faced by communities in the Metro-East region and explore potential strategies for mitigation and improvement.

Manufacturing Economy and Air Quality

The Metro-East region has historically been a hub for manufacturing activities, with industries such as steel production, refining, and chemical manufacturing contributing to the local economy. While these industries have provided employment opportunities and economic growth, they have also been associated with environmental degradation, particularly concerning air quality. The combustion of fossil fuels in manufacturing processes, as well as the release of pollutants from industrial facilities, can result in the emission of harmful pollutants such as particulate matter (PM), volatile organic compounds (VOCs), and nitrogen oxides (NOx), all of which can negatively impact air quality [1].

Traffic Patterns and Air Pollution

In addition to industrial activities, traffic patterns in the Metro-East region also contribute to environmental issues such as poor air quality. The region's proximity to major transportation routes, including highways and railways, results in significant vehicular traffic, particularly from trucks transporting goods to and from industrial facilities. Vehicle emissions, including those from diesel-powered trucks, are a major source of air pollution in urban areas, emitting pollutants such as nitrogen dioxide (NO2), sulfur dioxide (SO2), and carbon monoxide (CO), which can have adverse effects on human health and the environment [2].
