ResumoThe deposition of air pollutants in the Bergen region, Western Norway, is investigated by a very simple and inexpensive method. Dry snow was sampled from the ground at 46 locations just after a snowfall and then three days later. Consistent and logical patterns for the two days were found for sulphate, magnesium, calcium, zinc, pH value and conductivity. The rate of the dry deposition in the rural areas was significantly smaller than the rate of washout/rainout. In the city area these two rates were of the same magnitude.
