👉 Fumes, particularly those from biological sources, are volatile organic compounds produced by various biological processes and can have significant impacts on health and the environment. These fumes often arise from the decomposition of organic matter, microbial activity, or the use of biological materials in industrial settings. Common biological fumes include volatile fatty acids, ammonia, hydrogen sulfide, and various aldehydes, which can irritate the respiratory system, cause eye and skin irritation, and in high concentrations, lead to more severe health issues such as respiratory failure or poisoning. Additionally, some biological fumes, like those from mold or bacterial byproducts, can contribute to the formation of secondary pollutants, exacerbating air quality problems. Understanding and managing these fumes is crucial for maintaining safe indoor and outdoor environments.
