Air improved in Moravia-Silesia but smog remains

There was an improvement in the air quality in the Moravia-Silesia region on Saturday following several days of extremely poor air. However, airborne dust levels were still above the maximum permitted 50 microgrammes per cubic metre in some places. The Czech Hydrometeorological Institute recently announced a smog alert in the region; it was the first time it had declared such an alert since being given that power in November.
