Air pollution worsens in Moravia-Silesia

Air pollution is reported to have worsened severely in parts of Moravia and Silesia overnight with the concentration of dust particles in the air far exceeding permitted norms at 13 of 15 monitoring stations. According to data from the Czech Hydro-meteorological Institute the concentration of harmful substances in the air is more than double the permitted norm in Ostrava and Karvina where 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.
