👉 Livestock fumes are primarily composed of gases and volatile organic compounds (VOCs) produced by animals, particularly from their digestive processes and respiration. These emissions include ammonia, methane, hydrogen sulfide, and various other chemicals. Ammonia, a common byproduct, can be particularly potent, contributing to odors that are often described as strong, pungent, and unpleasant. Hydrogen sulfide, known for its foul smell similar to rotten eggs, is another significant component, though it is less common. These fumes can also contain other gases like carbon dioxide and volatile fatty acids, which contribute to the overall odor and can have health implications if inhaled in high concentrations, affecting both animal welfare and human health in nearby areas.
