Nos habitations , de plus en plus herm\u00e9tiques et isol\u00e9es thermiquement , peuvent concentrer des polluants \u00e0 origine diverse :<\/p>\n
– La pollution urbaine<\/strong>, qui p\u00e9n\u00e8tre \u00e0 pr\u00e8s de 90 % \u00e0 l\u2018int\u00e9rieur des b\u00e2timents, v\u00e9hiculant des gaz irritants provenant de la circulation automobile et des activit\u00e9s industrielles : l\u2019ozone (O3) et les oxydes d\u2019azote (NOx)\u2026<\/p>\n – Le monoxyde de carbone<\/strong> (CO), inodore et invisible, provoque des intoxications graves ; il provient d\u2019une mauvaise combustion dans les chaudi\u00e8res et chauffe eau, les cuisini\u00e8res, les chemin\u00e9es et po\u00eales, mais aussi du tabagisme.<\/p>\n – Les COV<\/strong> (Compos\u00e9 Organiques Volatiles). Ils appartiennent \u00e0 diff\u00e9rentes familles chimiques et sont pr\u00e9sents dans de nombreux produits et mat\u00e9riaux. Ils peuvent se d\u00e9gager des mat\u00e9riaux de construction, de l\u2019ameublement ou de la d\u00e9coration. Les bombes a\u00e9rosols, les produits de bricolage, les produits de nettoyage…<\/p>\n – La vapeur d\u2019eau<\/strong>. L\u2019air int\u00e9rieur ne doit \u00eatre ni trop sec, ni trop humide et un exc\u00e8s d\u2019humidit\u00e9 acc\u00e9l\u00e8re le d\u00e9veloppement des blattes et acariens et la pr\u00e9sence de moisissure. La respiration, le linge qui s\u00e8che, la salle de bain et la cuisine, les plantes vertes\u2026 sont autant de sources de vapeur d\u2019eau qu\u2019il faut veiller \u00e0 r\u00e9guler.<\/p>\n – Le radon<\/strong> : c\u2019est un gaz lourd radioactif diffus\u00e9 naturellement par le sol et qui stagne dans les habitations.<\/p>\n – Le tabac<\/strong> : plus de 3000 substances ont \u00e9t\u00e9 identifi\u00e9es dans la fum\u00e9e du tabac dont la nicotine responsable de l\u2019accoutumance, les goudrons responsables des cancers et le monoxyde de carbone.<\/p>\n Ces polluants sont directement responsables de diverses pathologies (irritations, asthme, maladies allergiques, pathologies broncho-pulmonaires, intoxications aigu\u00ebs, cancers, etc…).<\/p>\n Il existe 3 groupes de polluants de l’air int\u00e9rieur :<\/p>\n Les Agents Biologiques :<\/em><\/strong><\/p>\n . Allerg\u00e8nes (acariens, blattes, chats, pollens,\u2026)<\/p>\n . Bio-effluents humains : monoxyde de carbone (C0), compos\u00e9 organiques volatiles (COV)\u2026<\/p>\n . Micro-organismes : bact\u00e9ries, virus, moisissures…et leurs \u00e9missions (COVm, endotoxines, mycotoxines)…<\/p>\n Les Agents Physiques :<\/em><\/strong><\/p>\n . Amiante,<\/p>\n . Champs \u00e9lectromagn\u00e9tiques,<\/p>\n . Fibres min\u00e9rales artificielles,<\/p>\n . Radon,<\/p>\n . Particules inertes,<\/p>\n . Humidit\u00e9, …<\/p>\n Les Agents Chimiques :<\/em><\/strong><\/p>\n . CO1<\/p>\n . C0\u00b2<\/p>\n . FTE,<\/p>\n . M\u00e9taux lourds,<\/p>\n . 03,<\/p>\n . COV<\/p>\n . NOx<\/p>\n .
