Abstract: | A method of calculating the atmospheric concentration of a volatile chemical in confined volumes is presented and illustrated which uses the fugacity concept to simplify the manipulation of the various transport and reaction terms. The method is particularly suitable for estimating exposure to chemicals which may be released by evaporation into a house, work place, or partially confined outdoor environment in which there are several volumes (eg. rooms) with known ventilation characteristics. Illustrative calculations are presented. |
