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.
