👉 Eugene Fumes refer to a set of volatile organic compounds (VOCs) that were historically released by refrigerants, particularly those containing chlorofluorocarbons (CFCs) and later hydrochlorofluorocarbons (HCFCs), used in air conditioning systems. These chemicals are known for their strong, unpleasant odor, often described as a mix of sulfur, ammonia, and other pungent smells. The term "Fumes" highlights the lingering, often hazardous nature of these emissions, which can persist in the air even after the refrigeration system has been decommissioned. Exposure to eugene fumes can cause immediate irritation to the eyes, nose, and throat, and in high concentrations, can lead to more severe health issues such as respiratory problems and neurological effects. Despite being largely phased out due to environmental concerns, their lingering presence continues to pose risks in older buildings and systems.
