The worst situation is now prevailing in large cities where the amount of motor cars emitting noxious fumes has recently risen several times. Though there is still a long way to the ideal, measurements indicate that the air above Poland is getting cleaned slowly. Comparing to the beginning of the 90s, the emission has been meaningfully restricted of such harmful gases as sulphur dioxide, nitrogen oxide, and of industrial dusts.
Some amelioration is visible, too, as regards the quality of river waters.
We are far from self-satisfaction. Still there exist such areas of this country, in which the permissible concentration standards of impurities are exceeded. However, for at least five years an economic growth has been noted in Poland, and despite that the emission of noxious substances keeps declining all the time. We have begun to care for environmental protection. At present, Polish cities seem to constitute the biggest problem.
