👉 Adjacent fumes refer to the volatile organic compounds (VOCs) and other harmful substances that can be released into the air from nearby sources, even when no direct emission is occurring. These fumes often originate from activities such as cooking, cleaning, or using certain products like paints, solvents, and adhesives. For instance, burning incense or candles can release aromatic compounds and other VOCs that linger in the air, potentially causing respiratory issues or irritating the eyes and nose. Similarly, strong cleaning agents or paints can emit fumes that mix with outdoor air, affecting air quality in a localized area. Understanding adjacent fumes is crucial for maintaining indoor air quality and protecting health, especially in enclosed spaces where ventilation may be limited.
