Heavy smog in Prague as blight continues in east of country

After several days of heavy smog in the far east of the Czech Republic, conditions have worsened in the capital as well. Prague monitoring stations on Tuesday moved the air-quality rating to five on a scale of six, with inversion preventing an improvement. 14 out of 15 stations in Prague reported that flue dust levels had exceeded the limit as of Tuesday evening. Meanwhile, a station in the industrial area of Třinec has recorded flue dust levels of seven times the limit, which is 50 micrograms per cubic metre; polluters in that region were ordered to reduce production. Senior citizens, children and the chronically ill have been advised to restrict their time out of doors in the areas in question.
