Determination of Possible Effects of Air Pollutants for the Kocaeli-Dilovasi
Journal Title: Aksaray University Journal of Science and Engineering - Year 2017, Vol 1, Issue 2
Abstract
In the study, it is aimed to determine the possible effects of air pollutants (CO, SO2, NO, NO2, O3) in the Kocaeli-Dilovasi region where the industry is concentrated with ALOHA software. In the modeling studies, air pollutant concentration data for the years 2010 and 2017 of the National Air Quality Monitoring Network established by the Ministry of Environment and Urban Planning was used. Modeling studies were conducted through direct source and instant release scenarios. Toxic effects were identified for all air pollutants and the largest impact areas were identified for the toxic zone. For NO and NO2, the effect distance was determined to be 10km in red (>20 ppm, PAC-3), orange (>12 ppm, PAC-2) and yellow (0.5 ppm, PAC-1) every two years. The worst-case scenario was considered with the selection of the atmospheric F stability class. Toxicity as well as combustion and explosion effects were determined for CO air pollutant. For the year 2010, the flammable region, red (>75000 ppm, 60% LEL) = 2.2 km and yellow (>12500 ppm, 60% LEL) =distance of 4.7km effects were obtained. It was determined that the detonation explosion effects gave larger impact distances (<3km) and showed all explosion effects of the destructions of buildings (>8 psi), serious injury likely (>3.5 psi), and shatters glass (>1.0 psi). It was indicated that concentrations for CO and O3 air pollutants declined in 2017 and so resulted in a decrease in all impact values. It has been predicted that environmental regulations could be more effective if quantitative assessments of the possible effects of air pollutants were made.
