Frisättning

Frisättning is a Swedish term that denotes the act of releasing or freeing something that has been restrained, contained, or withheld. The word covers a broad idea of discharge, emission, or liberation, and its precise meaning depends on the context in which it is used.

In biology and medicine, frisättning commonly refers to secretion or exocytosis, the process by which cells release substances such as hormones, neurotransmitters, enzymes, or cytokines into surrounding tissue or the bloodstream. The term is also used in pharmacology to describe the release of an active drug from a dosage form, a process influenced by formulation and environmental conditions.

In environmental science, frisättning can refer to the release or emission of pollutants, gases, vapors, or other substances into air, water, or soil. This usage encompasses both intentional releases and accidental spills, and it is often discussed in the context of safety, regulation, and impact assessments.

In legal or corrections contexts, frisättning describes release from custody, such as parole or conditional freedom granted before the end of a sentence. This sense emphasizes the transition from confinement to freedom under specified conditions.

Because frisättning spans multiple disciplines, its exact meaning is specialized to the field. When encountering the term, it is important to consider the domain and accompanying terms to determine whether it refers to biological secretion, chemical emission, environmental release, or legal release.
