👉 The Louisville Fumes refer to a series of air quality issues that have plagued the city of Louisville, Kentucky, particularly along I-75 and its surrounding areas. These fumes are primarily caused by vehicle emissions, including nitrogen oxides (NOx) and particulate matter (PM), which are exacerbated by heavy traffic and industrial activities. The result is a persistent haze that can significantly degrade air quality, posing health risks such as respiratory issues and cardiovascular problems to residents and visitors alike. Efforts to mitigate these fumes include stricter emissions standards for vehicles, increased use of cleaner fuels, and the promotion of public transportation and alternative modes of travel like biking and walking.
