Mesure de la concentration aérienne de COV terpéniques (dont le limonène) selon plusieurs procédures lors de pulvérisations d’un mélange d’huiles essentielles

Sprays and diffusers as indoor air fresheners: Exposure and health risk assessment based on measurements under realistic indoor conditions

“…5 The exposure levels associated with the use of noncombustible air fresheners have been assessed in other studies. 6,14,15,[27][28][29][30][31][32] These studies were based on other hypotheses, other types of measurements and other methods. The main identified differences are related to the use of emission data measured in test chambers, the use of models to estimate exposure, the selected products (a great variability in emissions has been observed within the same type of noncombustible air freshener), 8,10 the selected air change rate and volume of the room where noncombustible air fresheners are used, the location of the measuring instrumentation, for example, the distance to the tested product, and the availability of detailed information on the practices of the considered users.…”

Volatile organic compound and particulate matter emissions from an ultrasonic essential oil diffuser

“…Indoor scenting sources come in a wide variety of forms, including incense, wax warmers, air fresheners, candles, candle‐heated essential oil, Berger lamps, and ultrasonic diffusers. These sources produce both particulate matter (PM) and volatile organic compounds (VOCs), and as such have the potential to significantly alter the makeup of the indoor atmosphere in which they are used 1–11 . Indoor scenting sources using combustion (such as candles and incense) have received significant attention in the literature 2,3,6,12–14 .…”

“…These sources produce both particulate matter (PM) and volatile organic compounds (VOCs), and as such have the potential to significantly alter the makeup of the indoor atmosphere in which they are used. [1][2][3][4][5][6][7][8][9][10][11] Indoor scenting sources using combustion (such as candles and incense) have received significant attention in the literature. 2,3,6,[12][13][14] Particular attention has been paid to the physical and psychological effects of exposure to the PM and VOCs produced by these sources.…”

Pollution intérieure : comment améliorer la qualité de l’air ?

“…On s'étonne dans ces conditions que l'asthme demeure la première maladie chronique de l'enfance. Et vous lirez dans les pages qui suivent que les mélanges d'huiles essentielles pulvérisés selon diverses procédures sont source de COV terpéniques [12]. L'équipe de Strasbourg pilotée par de Blay et al a montré qu'un mélange pulvérisé de 41 huiles essentielles et utilisé selon les recommandations du fabricant produisait du limonène à des taux supérieurs aux normes 2 ainsi que des concentrations très importantes en COV totaux.…”

“…En Allemagne, la valeur maximale dans les locaux professionnels est de 110 mg/m 3 (20 ppm) pour le limonène ; pour l'habitat la dose limite d'exposition serait de 450 g/m 3 et correspond au seuil d'irritation. Pour les COV totaux de l'habitat une exposition à moins de 200 g/m 3 serait sans effet sur la santé et une exposition à plus de 3000 g/m 3 cause des irritations, au-dessus 25 mg/m 3 les effets deviennent toxiques [12]. [13] et que l'implication des COV était probable dans la modification de la réponse immune et l'apparition d'une sensibilisation [14].…”
