👉 Chart fumes refer to the visible, often pungent, plumes of smoke or haze that can appear in the air above industrial areas, particularly those with coal-fired power plants, refineries, or other large-scale combustion processes. These fumes are primarily composed of particulate matter, including soot, ash, and other fine particles, as well as gases like sulfur dioxide, nitrogen oxides, and volatile organic compounds. The visibility of these fumes can vary from faint to dense, depending on the concentration of pollutants and atmospheric conditions. While often associated with industrial pollution, chart fumes can also occur in urban settings due to vehicle emissions or other human activities. Exposure to high levels of chart fumes can lead to respiratory issues, eye irritation, and other health problems, making air quality monitoring crucial in such areas.
