ENVIRONMENTAL BURDEN BY TOTAL SEDIMENT DUSTIN THE CITY OF ZENICA

The city of Zenica belongs to one of the most important industrial centers in Bosnia and Herzegovina. Due to the presence of industrial plants, especially metallurgical plants, but also due to a large number of small home fireplaces and the geographical location, air pollution in the Zenica valley is very high. Through continuous and dedicated air quality measurement, excessive air pollution was determined in the urban area of Zenica, i.e. limit values for total sediment dust were exceeded in some parts of the Zenica valley. The paper provides an analysis of the results of monitoring the total sediment dust and the content of heavy metals such as lead, cadmium, zinc, and iron in the total sediment dust for the period 2019-2021to determine the environmental burden and the average annual and maximum monthly trends of the total sediment dust in the Zenica valley. The analysis shows that emissions originating from industrial sources significantly burden the environment with sediment dust, especially in the zone up to about 3.5 km from the sources located in the industrial zone of the Zenica valley
