- Abstract
Determinations of immission concentration of benzene were carried out at 4 sites in area near the coke plant in Arcellor Mittal Zenica (AMZ) and 4 sites in the industrial complex of Global Ispat Coke Industry Lukavac (GIKIL). Measurements were performed in AMZ in order to determine the air quality and to determine a possible cause of the high concentration of benzene at the automatic measuring station in Tetovo (AMS Tetovo), in GIKIL to determine the possible source of emissions and to compare the results. To measure the concentration of benzene GASMET DX4030 portable gas analyzer was used with a Fourier Transform Infrared (FTIR) spectrometer, the measurement range of 0,01 ppm to 200 ppm. Positions of sampling sites were selected in relation to the nearest populated area, and based on the wind rose. On location AMZ at the sampling site SZ1 an average concentration of benzene was 44,47 μg/m³ and the maximum measured 139,2 μg/m³. The sampling site SZ2 was the nearest to the coke plant, the average benzene concentration was 117,28 μg/m³ and the maximum measured 243,60 μg/m³. At the sampling site SZ3 the average concentration of benzene was 99,69 μg/m3 and the maximum 313,20 μg/m³. The sampling site SZ4 was located north-east of the coke plant, the average measured concentration of benzene was 108,13 μg/m3 while the highest concentration was 278,40 μg/m³. On location GIKIL, at the sampling site SL4 the highest concentration of benzene of 5000 μg/m3 and the lowest of 1450,10 μg/m3 at the SL4 were measured. At the AMS Tetovo, in the period of measurement, the average benzene concentration was 1,62 μg/m³, and the highest value was 2,50 μg/m³. On the basis of the measurements it can be concluded that air quality in the immediate vicinity of the coke plant does not meet clean air quality with regard to the content of benzene.
