Last night in Zenica, there was once again an increased concentration of dust and sulfur dioxide SO2 in the air.
The concentration of sulfur dioxide SO2 was apparent in the city center, at 320 micrograms per cubic meter, which is a red alert.
The concentration of dust in the air was measured even at 980 micrograms per cubic meter, and thus also showed a red alert to signal a warning.
