👉 Plant fumes, also known as volatile organic compounds (VOCs), are airborne chemicals released by plants through their leaves and stems. These emissions occur naturally as part of a plant's metabolic processes, particularly during photosynthesis and respiration. Common plant fumes include terpenes, which give many plants their distinctive scents, such as the citrus aroma of oranges or the piney smell of conifers. However, some fumes can be harmful when inhaled in high concentrations, potentially causing respiratory issues, headaches, or long-term health effects like liver and kidney damage. Indoor plants, especially those with large leaf surfaces, can release more volatile compounds, making it important to monitor air quality, particularly in enclosed spaces like homes and offices.
