👉 The "Frankfurt Fumes" refer to a long-standing environmental issue stemming from the city of Frankfurt am Main, Germany. This phenomenon is primarily caused by the high levels of air pollution, particularly from industrial emissions and vehicular exhaust, concentrated in the densely populated urban area. The city's industrial past, with numerous factories and chemical plants, has left a legacy of pollutants that persist in the air. Additionally, heavy traffic from both local commuters and international flights contributes significantly to the problem. These pollutants, including particulate matter, nitrogen oxides, and volatile organic compounds, have led to poor air quality, affecting residents' health and visibility. Efforts to mitigate the issue include stricter emission standards, increased public transportation, and initiatives to reduce industrial emissions, but the legacy of Frankfurt's industrial era continues to impact the city's air quality.
