Gesundheit: Beurteilung nach dem TVOC-Konzept

· Vor diesem Hintergrund kann das TVOC -Wert Konzept (TVOC, total volatile organic compounds) als Bewertungsmöglichkeit herangezogen werden. Grundsätzlich ist ein solches Konzept nicht toxikologisch begründet und kann daher nicht direkt als ein Kriterium zur Beurteilung gesundheitlicher Wirkungen herangezogen werden.

Flüchtige organische Verbindungen – Wikipedia

Flüchtige organische Verbindungen (englisch volatile organic compounds, kurz VOC) ist die Sammelbezeichnung für organische, also kohlenstoffhaltige Stoffe, die bei Raumtemperatur oder höheren Temperaturen durch Verdampfen (umgangssprachlich „Verdunsten“) in die Gasphase übergehen, also flüchtig sind. Das Gas Methan, CH 4, ist oft nicht eingeschlossen, manchmal explizit …
