Moravia and Silesia plagued by smog
Air pollution is reported to have worsened severely in parts of Moravia and Silesia with the concentration of dust particles in the air far exceeding permitted norms at all but one of the 15 monitoring stations in operation. According to data from the Czech Hydro-meteorological Institute the concentration of harmful substances in the air is more than three times the permitted norm. The authorities have advised elderly people and children to stay indoors as much as possible. The situation is being closely monitored by city hall which has the right to call a smog alert and ask industrial plants to scale-down production.
