What term is used for emissions that escape into the ambient air without being vented through a stack?

Fugitive emissions refer specifically to those emissions that are released into the atmosphere without being captured or channeled through a designated exhaust system, such as a smokestack or vent. These emissions typically result from leaks or unintentional releases during various processes, including manufacturing, transportation, and storage of materials. Examples of fugitive emissions can include gas leaks from pipelines, evaporative losses from fuel storage, and emissions from the handling of solid waste.

Understanding the nature of fugitive emissions is crucial in environmental health and safety, as they can contribute to air pollution and have significant impacts on both human health and the environment. Proper monitoring and management strategies are vital to reduce these types of emissions, ensuring compliance with environmental regulations and protecting public health.
