👉 Merge fumes refer to the unpleasant, often irritating effects experienced when two or more air pollutants combine in the atmosphere, creating a more toxic and harmful mixture than either pollutant alone. This phenomenon occurs when volatile organic compounds (VOCs) from solvents, paints, and other chemicals react with nitrogen oxides (NOx) in the presence of sunlight, forming ground-level ozone and other secondary pollutants. These reactions can lead to respiratory issues, eye irritation, and damage to vegetation, making air quality significantly worse in urban areas or near industrial sites.
