Parts of Moravia plagued by smog
A smog alert remains in effect for parts of Moravia, particularly the Moravia-Silesia, Olomouc and Zlín regions, the Czech Hydrometeorological Institute said. The alert was declared earlier this week over dust emission values that in some places twice exceed the permitted norms. The situation is not likely to improve in the next few days, meteorologists said. Children, chronically ill and elderly people have been advised to stay indoors. The Moravia-Silesia region is one of the most polluted in the country, with heavy industry, traffic and coal heating among the major factors.
