👉 Campbell fumes refer to the unpleasant, often acrid odor associated with the breakdown of organic materials, particularly those containing sulfur compounds like those found in decaying vegetation, animal waste, or certain industrial chemicals. This odor is named after the Scottish chemist Sir William Campbell, who first described it in the 19th century. The term "fumes" highlights the volatile and pervasive nature of the smell, which can spread quickly in enclosed spaces. Campbell fumes are typically characterized by a sharp, pungent scent that can be both offensive and irritating to the nose and lungs, often leading to headaches, nausea, and respiratory issues. While generally not harmful in trace amounts, prolonged exposure can exacerbate existing health conditions or cause discomfort.
