👉 Fumes are fine particles or vapors that are released into the air from various sources, often as a result of chemical reactions, combustion processes, or exposure to certain substances. These tiny particles can be inhaled deeply into the lungs, bypassing the body’s natural defenses and potentially causing respiratory issues, irritation, or even long-term health problems like lung disease or cancer. Common sources include industrial emissions, cigarette smoke, and fumes from solvents or paints. Proper ventilation and protective measures are essential to minimize exposure and mitigate the harmful effects of fumes.
