In the Moravian-Silesian Region, the dispersion conditions are still worse. A smog situation remains in force in part of the region, which meteorologists declared from Sunday to Monday due to high concentrations of polluting dust in the air. The limit for fly dust, 50 micrograms per cubic meter, has been exceeded at measuring stations. This is according to information from the Czech Hydrometeorological Institute (ČHMÚ).
In the morning, the average daily concentrations of fly dust ranged from 67 to 151 micrograms per cubic meter. According to the latest data of the three-hour average, the worst situation in the region before 08:00 was in Nosovice in the Frýdek-Místek region, where 218 micrograms per cubic meter were measured, so the meteorologists still described the situation there worsened.
The smog situation in the region is valid for the Ostrava, Karviná, and Frýdek-Místek regions. People there should refrain from increased physical exertion while outdoors, during which they would breathe more intensively. The recommendation applies especially to people with chronic respiratory problems, heart disease, the elderly, and young children. At the same time, meteorologists say it is advisable to prioritize traveling by public transport.
Several factors affect air quality in the region. In addition to geographical location and weather conditions, the accumulation of emissions from industrial sources, local heating plants, transport, and, to a large extent, especially in winter months, the transfer of emissions from Poland plays a significant role.
