In der Beschreibung der Chemikalie "Formaldehyd" schreibt die amerikanische Behörde EPA (Umweltschutzbehörde): " Es gibt Nachweis, daß einige Personen Sensibilität gegenüber Formaldehyd entwickeln können."

Hier das Zitat über die gesundheitlichen Beeinträchtigungen durch Formaldehyd:
Health Effects
Formaldehyde, a colorless, pungent-smelling gas, can cause watery eyes, burning sensations in the eyes and throat, nausea, and difficulty in breathing in some humans exposed at elevated levels (above 0.1 parts per million). High concentrations may trigger attacks in people with asthma. There is evidence that some people can develop a sensitivity to formaldehyde. It has also been shown to cause cancer in animals and may cause cancer in humans. Health effects include eye, nose, and throat irritation; wheezing and coughing; fatigue; skin rash; severe allergic reactions. May cause cancer. May also cause other effects listed under "organic gases." EPA's Integrated Risk Information System profile - http://www.epa.gov/iris/subst/0419.htm
