👉 Fumes are fine particles or droplets of liquid that are released into the air, often as a byproduct of combustion processes, chemical reactions, or industrial activities. These particles can originate from sources like burning fuels (e.g., wood, coal, gasoline), industrial emissions, or even natural sources like volcanic eruptions. In the atmosphere, fumes can remain suspended for varying durations, depending on factors such as wind, temperature, and humidity. They pose health risks when inhaled, as they can irritate the respiratory system, exacerbate conditions like asthma, and in severe cases, lead to more serious health issues. Proper ventilation and emission controls are crucial to mitigate the adverse effects of fumes.
