👉 Substantially fumes refer to visible, often cloudy or thick plumes of gas or particulate matter that rise into the air from various sources, typically industrial processes, chemical reactions, or combustion activities. These fumes can contain a wide range of substances, including toxic gases like carbon monoxide, sulfur dioxide, and volatile organic compounds (VOCs), as well as fine particles such as soot and dust. The term "substantial" indicates that these emissions are significant enough to pose health risks or environmental concerns, potentially affecting air quality and human health over a wide area. Proper ventilation and safety measures are crucial to mitigate the impact of these fumes.
