👉 Meyer fumes, also known as formaldehyde fumes or acetaldehyde fumes, are a type of volatile organic compound (VOC) primarily emitted by formaldehyde, a common chemical used in various industrial and household products such as furniture, building materials, and cleaning agents. These fumes can cause a range of health issues, including eye, nose, and throat irritation, headaches, and respiratory problems, particularly with prolonged or high exposure. The term "Meyer" refers to the German chemist Hermann Meyer, who first identified formaldehyde in 1848, though the phenomenon was recognized earlier by other scientists. Exposure to these fumes is especially concerning in enclosed spaces like homes, offices, and workshops where formaldehyde levels can build up, making proper ventilation crucial to mitigate health risks.
