ABSTRACT
There is a method described for determination the amount of air pollutants incorporated by breathing. The method is based on the non-invasive and continuous sampling of air contents. In contrary to common methods there is no need for any assumptions about the retention rate. Working principle: The breathing flow drives two pneumatic circuits related to inspiration and respiration respectively. The respirometer signal controls the two membrane pumps and delivers the respiration volume. In every moment a little but fixed percentage of breathing air is sucked by a pump through one of the two charcoal tubes. After the quantitative analysis of the probes you know the mass difference of the pollutant and because of the choice relation to respiration volume you can calculate the incorporated dose.
