👉 The falling fumes describe a visible and often unpleasant phenomenon where toxic or noxious gases or vapors, released from a source such as a chemical spill, industrial accident, or faulty equipment, gradually descend and dissipate into the air. These fumes can be dark, thick, or tinged with a chemical odor, often indicating the presence of harmful substances like carbon monoxide, sulfur dioxide, or volatile organic compounds (VOCs). As they settle, they may form a haze or pool near the source, gradually dispersing into the surrounding environment, potentially affecting air quality and posing health risks to nearby individuals.
