Fumes are small particles or gases that are released into the air, often as a result of burning or chemical reactions. They can come from various sources, including vehicles, industrial processes, and household products. Fumes can contain harmful substances that may affect air quality and human health. Exposure to fumes can lead to respiratory issues, headaches, and other health problems. Common examples of fumes include those from smoke, exhaust, and chemical solvents. It is important to ensure proper ventilation and safety measures when working with or around materials that produce fumes to minimize health risks.
