Outre les \u00e9missions li\u00e9es au transport et \u00e0 l\u2019industrie, les mat\u00e9riaux de construction (rev\u00eatements, isolants, colles) et de d\u00e9coration (peintures, vernis, lasures) constituent des sources de COV. La combustion du bois et des produits tels que les bougies et l\u2019encens (et \u00e9videmment le tabac) produit \u00e9galement des COV. Les plus courants sont les hydrocarbures aromatiques (comme le benz\u00e8ne), les ald\u00e9hydes (comme le formald\u00e9hyde), les terp\u00e8nes, les \u00e9thers et les alcools que l\u2019on retrouve notamment dans les solvants.<\/p><p>La temp\u00e9rature et l\u2019humidit\u00e9 relative peuvent influencer l\u2019\u00e9mission de COV d\u2019un mat\u00e9riau. Certains mat\u00e9riaux vont \u00e9mettre des COV pendant plusieurs ann\u00e9es, d\u2019autres seulement sur une courte p\u00e9riode. Des COV peuvent \u00e9galement r\u00e9agir chimiquement avec d\u2019autres et former de nouveaux compos\u00e9s (comme l\u2019ozone).<\/p><p>Les COV correspondant \u00e0 des substances diff\u00e9rentes, leur valeur seuil est propre \u00e0 chacune. Les valeurs seuils indiqu\u00e9es par les d\u00e9tecteurs de qualit\u00e9 de l\u2019air \u00e0 destination des particuliers correspondent donc \u00e0 une moyenne et sont donc peu exploitables. Renouveler l\u2019air int\u00e9rieur en volume suffisant est donc indispensable afin de limiter les COV dans l\u2019habitat.<\/p><p>\ud83d\udcd6 <a href=\"https:\/\/www.anses.fr\/fr\/system\/files\/AIR2004et0011Ra-2.pdf\" target=\"_blank\" rel=\"noopener\"><span style=\"text-decoration: underline;\">AFSSET (2009) &#8211; <em>Compos\u00e9s organiques volatiles et environnement int\u00e9rieur<\/em>, 91 p.<\/span><\/a><\/p><p>\ud83d\udcd6 Desauziers V., Plaisance H., Costarramone N., Dallies G., Achard S., Al Zallouha M.
