Abstract
The measurements were performed, for the fifth time, in 51 urban areas and, as a comparison, in 40 rural areas close to urban measuring points. The results were: SO2 - the concentrations measured amounted to 30-36 % of recommended upper limits and are, with a few exceptions, the lowest values in this series of measurements. Soot - five daily mean values higher than the recommended upper limits were recorded, three of which in the same area. Except these, the highest daily mean values amounted to 64-70 % of the upper limit, and the half-yearly means to 35-40 %. NO2 - at two locations, a daily mean value higher than the recommended upper limit was measured. It is possible that the hourly upper limits were exceeded at most of the locations. Comparison with earlier measurements does not indicate any reduction of the NO2-load. The half-yearly mean values were higher than last season at 27 locations. For southern Sweden, episodes of transfrontier pollution were probably a major air pollution source. (many tabs. and figs.).
