and includes:<\/p>\n<ul>\n<li>an annual assessment of building ventilation systems;<\/li>\n<li>an indoor air quality self-diagnosis (at least every 4 years);<\/li>\n<li>a campaign to measure regulated pollutants such as formaldehyde, benzene, carbon dioxide (CO<sub>2<\/sub>) and, in some cases, tetrachloroethylene (or perchloroethylene);<\/li>\n<li>drawing up an action plan to improve indoor air quality.<\/li>\n<\/ul>\n<p>The current regulatory surveillance was revised by the 4<sup>th<\/sup> National Environmental Health Plan (2021-2025) &#8220;One environment, one health&#8221; and came into force on January 1, 2023. In particular, it provides for: <\/p>\n<ul>\n<li>a measurement of carbon dioxide concentration as part of the annual assessment of ventilation systems;<\/li>\n<li>key stages in the life of the building that may have an impact on indoor air quality;<\/li>\n<li>a threshold for triggering pollutant measurement campaigns, and the deadlines for their completion.<\/li>\n<\/ul>\n<p>There are many sources of volatile organic compounds (VOCs) in indoor air. VOCs are organic compounds that can easily be found in gaseous form in the earth&#8217;s atmosphere. They constitute a very broad family of compounds, and have the particularity of having a very low boiling point, which gives them the ability to spread more or less far from their place of emission, resulting in direct and indirect impacts on animals and nature.  <\/p>\n<p>VOCs can be of anthropogenic origin (from refining, evaporation of organic solvents, unburned, etc.) or of biotic origin. VOCs can be defined according to their use: solvent, degreaser, preservative, cleaning agent, etc. <\/p>\n<p>Sources of VOCs in indoor air can include the following:<\/p>\n<ul>\n<li>Maintenance and cleaning products: certain household products, such as detergents, cleaning products and air fresheners.<\/li>\n<li>Construction and finishing materials: certain materials such as paints, varnishes, glues and carpets.<\/li>\n<li>Furniture and objects: certain items such as mattresses, cushions and toys.<\/li>\n<\/ul>\n<p>It&#8217;s important to note that each of these sources emits very few VOCs, but their accumulation can create a problem in terms of overall final concentration (total VOCs or TVOCs) in indoor air.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div
