Studie Duftstoffe schädigen das Immunsystem

Abstract
Effects of inhalation of fragrance chemicals on the immune system
Inhalation of the fragrance chemicals, isoeugenol and cinnamal, by mice resulted in immune reactions
in the respiratory tract. This was observed in experiments performed by the RIVM (National Institute
for Public Health and the Environment) of which results indicate that inhalation of some fragrance
chemicals could induce unwanted effects on the immune system.
Fragrance chemicals are common ingredients in such consumer products as cosmetics and scented
products. Several fragrance chemicals are known to cause allergy after skin exposure, but it is unknown
whether inhalation of these fragrance chemicals can cause allergic reactions or other unwanted immune
reactions. Till recently, it was assumed that inhalation of fragrance chemicals was harmless for
humans, because there was no exposure via inhalation. However, applying fragrance chemicals in
scented products used indoors, has changed this.
RIVM investigated the effects of inhalation of isoeugenol and cinnamal, fragrance chemicals that can
cause skin allergy. Mice were exposed to the fragrance chemicals via inhalation. Effects on the immune
system were measured using a respiratory lymph node assay, which measures cell proliferation in
lymph nodes of the respiratory tract.
Inhalation of both isoeugenol and cinnamal resulted in stimulation of the immune system of the
respiratory tract. The effects of isoeugenol were more pronounced than those of cinnamal. This is in
contrast with results observed after skin exposure, after which both these fragrance chemicals were
found equally potent in inducing skin allergy. This implies that effects of fragrance chemicals on the
immune system depend on the route of exposure.
Relevant routes of exposure should then be used to predict the hazard of inhaling these compounds:
skin for cosmetics and the respiratory tract for scented products. To obtain more insight into the
hazards of fragrance chemicals used in scented products, RIVM is advising assessment of more
fragrance chemicals in the respiratory lymph node assay.

Prima Fund Amazone.

Genau genommen müsste diese Erkenntnis bedeuten dass Schluss ist mit der
Versprüherei von Duftstoffen im öffentlichen Bereich, ohne dass jemand einen Einwand hervorbringen kann.
Ich denke an öffentliche Toiletten, Altenheime, Krankenhäuser, U-Bahnen, Kaufhäuser, etc.
