👉 Ian Fumes, also known as IFC, refers to a group of volatile organic compounds (VOCs) primarily emitted by diesel fuel and diesel engines. These compounds are notorious for their strong, pungent odor, often described as a mix of sulfur, ammonia, and other hydrocarbons, which can be overwhelming and unpleasant. Exposure to IFC can cause irritation to the eyes, nose, and throat, and in high concentrations, it can lead to respiratory issues, headaches, and even more severe health effects over prolonged exposure. Despite being regulated in many areas, IFC remains a concern due to its widespread presence in vehicle exhaust and industrial emissions.
