👉 Fumes are fine particles or vapors that can be released into the air from various sources, often as a result of combustion, chemical reactions, or the breakdown of materials. These particles can be toxic and pose significant health risks when inhaled, including respiratory issues, irritation of the eyes, nose, and throat, and in severe cases, long-term damage to lung function. Common sources of fumes include industrial processes, vehicle exhaust, burning fuels, and even household products like paints, solvents, and cleaning agents. The term "bases" in this context can refer to organic bases, such as ammonia (NH₃) or sodium hydroxide (NaOH), which can also produce harmful fumes when heated or reacted with other substances. Proper ventilation and protective measures are crucial to mitigate the risks associated with exposure to these toxic fumes.
