at emission levels have stabilised since the mid-7s, while there is as yet no sign of decline, in contrast to the other four water pollutants. In two cases (air: SO2; water: BOD,), there has been roughly steady-state trend in emissions over the entire period studied, again with signs of slight decline towards the end of this period. The result is steady decrease in specific emissions. Only in one case (air: dust) has there been major drop in emissionssince the start ofthe period studied. It would seem, however, that this success -which was again the. result of technical measures - has exhausted its potential: dust emissions have entered an almost steady-state phase since the mid-7s. In summary, the following statements can be made as regards the opening question: - In 4 of the 1 cases studied, there was found to be parallel trend between economic - In 5 of the 1 cases, the original trend towards identical dynamism of economic rowth and - In 2 of the 1 cases, there was steady decline in the specific environmental burden - Only in one case was there continuous decline in the absolute environmental burden Giventhesedataand theanalysisofthecauses,thefollowinganswercan begiventotheques- tion as to whether economic growth is accompanied by increasing environmental burdens or rather by relief of these burdens: If accumulating media are also taken into account forthe,,environmentaI burden", the strict connection between economic growth and environmental burdens is backed empirically, but also from theoretical point.of view; If considerations of the ,,environmental burdenl'are geared to the emission rates in transit- ory media alone, it can be seen that the dynamism of the linkwas broken in 6 of 9 cases; there was steady-state trend in 2 cases; however, the link between NOx and economic growth remains unbroken; Itcan beseen in theanalysis, however,thatthe breakin ofthedynamictrend wasachieved by identifiable political initiatives
