👉 Default fumes refer to the typical, often invisible or barely noticeable emissions that can be released from various sources, such as industrial processes, vehicle exhausts, and everyday activities like cooking or cleaning. These fumes are composed of a mixture of gases and particulates, including volatile organic compounds (VOCs), nitrogen oxides (NOx), carbon monoxide (CO), and other harmful substances. While many fumes are harmless at low concentrations, prolonged exposure can lead to health issues such as respiratory problems, headaches, and long-term damage to organs. The term "default" implies that these emissions are the typical or expected byproducts of common activities, though their levels can vary significantly based on environmental conditions, technology used, and regulatory standards.
