Description: Episodical long-range transport is the quasi-instantaneous peak event. It does not express the total dosage of pollutant carried over from the source area to some distant place. The purpose of the present paper is to obtain an average material balance of a pollutant leaving a given area. Available information from the OECD "Long Range Transport of Air Pollutants" is being used for this purpose. The IRCHA is one of the laboratories participating in this project. Our main sampling station is 37 km from the center of the Paris district. This position allows us to compute, based on emission data from the area and air pollution survey records, the amount of pollutant (total sulfur) leaving the region. We worked out this specific example because we had the first-hand, checked data. Out of a total emission of about 300 kT SO2/year (1972 figure) , over 50% may be accounted for as remaining inside the 37 km-radius circle. Gaseous and particulate dry deposition mechanisms are considered mainly responsible for this fact. Less than half of the total sulfur emission seems to be transported beyond the 37 km-radius limit. The exact aspect of the deposition function within the national territory is currently being researched.
