Pestât

Pestât is a term sometimes used to describe a strong, lingering smell, often an unpleasant one, that remains in a place after the source of the odor has been removed or has dissipated. It is distinct from a fresh smell, implying a residual scent that has settled into the environment. This could be a smell left behind by smoke, cooking, dampness, or other substances. The word itself suggests something that has permeated or stained the air.

The persistence of pestât can vary. Some smells might fade within hours, while others, particularly those related to strong chemicals or deeply embedded organic matter, can linger for days, weeks, or even longer. The intensity of the pestât is often related to the initial strength and nature of the odor's source, as well as the ventilation and materials present in the affected area. Porous materials like fabrics, carpets, and unsealed wood are known to absorb and retain odors more readily, contributing to a more noticeable pestât.

Attempts to remove pestât often involve thorough cleaning, airing out spaces, and sometimes the use of odor absorbers or neutralizers. Understanding the nature of the original smell can help in selecting the most effective method for its removal. While not a formal scientific term, "pestât" serves as a common descriptor for this common phenomenon of lingering odors.
