The use of passive collectors is suggested as a complementary method of SO2 immission control, in particular for the determination of territorial distribution and of long-term trends. Therefore, a filter paper prepared with soda solution and glycerol is exposed in a special hold weatherproof for one month at least, and afterwards a gravimetric sulphate determination will be carried out. First results indicate a high correlation between SO2 concentration and SO2 absorption rate.
