Assessment of atmospheric particulate matter and precipitating dust pollution in industrial area of Van province

In this study, both Turkish Standard methods and air quality modeling studies were carried out for PM10 and collapsed dust pollutants emitted from the ready-mixed concrete plant in Tusba, Van. Fistly dust sources were determined in the plant and their concentrations were examined at 3 points for PM10 and at 2 points for settled dust. In the measurements made according to the Turkish Standard methods, stock area, between two conveyor belts and bunker as well as PM10 concentrations are; 0.29 mg / Nm3, 0.98 mg / Nm3, 0.67 mg / Nm3. In the measurements made according to the Turkish Standard methods, the average concentrations of dust collapsed in the on-site roads and in the stock area in the first month were 50 mg / m2 / day and 151 mg / m2 / day, respectively. In the measurements carried out according to the Turkish Standard methods, mean concentrations of the 2nd month in the on-site roads and in the stock area are as follows; 68 mg / m2 / day, 163 mg / m2 / day. According to the results of AEORMOD modeling, stock area, and their annual concentrations are as follows between two conveyor belts, bunker as well as PM10 24-hour concentrations respectively; 8,91 µg / m3, 5,46 µg / m3, 6,77 µg / m3. It is 1,70 µg / m3, 0,60 µg / m3, 1,11 µg / m3. According to the results of AEORMOD modeling, the daily concentrations of dust deposited on the plant roads and in the stock area are as follows; 11.97 mg / m2 / day, 11.98 mg / m2 / day and annual concentrations respectively; 3.20 mg / m2 / day and 3.94 mg / m2 / day. When compared with the limit values set out in Annex-1 and Annex-2 of the Industrial Air Pollution Control Regulation, it is observed that the measured and calculated results are below the limit values.
