    Notes: Summary In a ventilated climatic chamber 32 subjects (in groups of two or three) were exposed in one experiment to the total sidestream smoke of cigarettes and in another experiment to the gas phase of cigarette smoke, which was obtained by filtering out the particulate matter. The degree of air pollution corresponded to 10 ppm CO in both experiments. The concentrations of the particulate matter, CO, NO, NO2 and HCHO were recorded. With a questionnaire, we determined the degree of annoyance and of subjective irritations of the eyes, nose and throat; eye blink rate was measured, as an objective indicator of eye irritation. Both exposures of air pollution produced nearly the same degree of annoyance, which indicates that the gas phase is to a large extent responsible for the annoyance due to cigarette smoke. On the other hand the objective and subjective eye irritation was very much lower with the gas phase than with the total smoke. This indicates that the particulate phase is to a very large extent responsible for the irritating effects.

    Description / Table of Contents: Zusammenfassung Um die akuten Reizwirkungen des Akroleins auf den Menschen zu erfassen, warden gesunde Versuchspersonen in einer Klimakammer verschiedenen Akroleinkonzentrationen im Bereich von 0 bis 0.60 ppm ausgesetzt. Es warden drei Versuchsserien durchgeführt: (a) 40 minütige Exposition von 53 VP zu einer kontinurierlich ansteigenden Akroleinkonzentration, (b) vier 1 1/2 minütige Expositionen von 42 VP zu verschieden hohen Akroleinkonzentrationen, und (c) 60 minütige Exposition von 46 VP zu einer konstanten Konzentration von 0.3 ppm Akrolein. Während der Exposition bestimmten wir periodisch die subjektiv wahrgenommenen Reizungen und die Belästigung sowie die Lidschlußfrequenz und die Atemfrequenz. Die subjektiven Reizungen, die Belästigung and die Lidschlußfrequenz nahmen in Abhängigkeit der Akroleinkonzentration sowie bis zu einem gewissen Grad in Abhängigkeit der Expositionsdauer zu. Die Atemfrequenz sank mit steigender Akroleinkonzentration. Die Veränderungen waren im Bereiche zwischen 0.09 und 0.30 ppm Akrolein signifikant. Die akuten Reizwirkungen bei der Exposition zu 0.3 ppm Akrolein erwiesen sich bereits nach 10 und 20 min als erheblich; aus dieser Sicht sollte der heute empfohlene US-Grenzwert von 0.3 ppm für 15 minütige Expositionen neu überprüft werden. Die Wirkungen von reinem Akrolein sind im Vergleich zu denjenigen, die durch den Nebenstromrauch von Zigaretten bei gleicher Akroleinkonzentration ausgelöst sind, nur gering: das Akrolein muß somit nur wenig an den Reizwirkungen durch den Nebenstromrauch beteiligt sein.
    Notes: Summary In order to investigate the acute irritation effects of acrolein on men, healthy subjects were exposed in a climatic chamber to different acrolein concentrations in the range between 0 and 0.60 ppm. Three experimental series were carried through: (a) 40 min exposure of 54 subjects to a continuously increasing acrolein concentration, (b) four 1 1/2 min exposures of 42 subjects to different acrolein concentrations and (c) 60 min exposure of 46 subjects to a constant concentration of 0.3 ppm. acrolein. Subjective irritations and annoyance as well as eye blinking rate and respiratory frequency were determined periodically during the exposures. Subjective irritations, annoyance and eye blinking rate increased as a function of acrolein concentration, as well as of exposure duration up to a certain degree. Respiratory frequency decreased with increasing acrolein concentration. The changes were significant in the range between 0.09 and 0.30 ppm acrolein. Acute irritations during exposure to 0.3 ppm acrolein proved to be considerable after 10 and 20 min already; from this angle, the actual US threshold limit value of 0.3 ppm for exposures of 15 min should be reexamined. The effects of pure acrolein are small compared to those produced by the side stream of cigarette smoke with the same acrolein concentration: therefore, acrolein is only to a minor extent responsible for the irritations caused by the side stream smoke.
