The Amount of Ambient Ozone and Nitrogen Dioxide that Relate with Traffic around Bueng Srithan in Khon Kaen University Area

Abstract

          Ozone is a secondary air pollutant. This is caused by the reaction between volatile organic compounds (VOCs) in the atmosphere. VOCs are classified as toxic substances that cause toxic air (Toxic Air), which ozone affects the body. Affect various systems of the human body. NO₂ is corrosive. Causing acid rain If inhaled into the respiratory system, lung tissue damage occurs. This descriptive cross sectional study was conducted to study air pollutants content in the Sithan Lake area. Khon Kaen University is the concentration of Ozone and NO₂ in the atmosphere and their relation to traffic. The study method was to count the number of vehicles passing through (vehicles) around the Sithan lake, looking for the correlation of traffic volume in each phase with ozone and NO₂. Data were collected for 7 days, each day divided into 4 periods of 3 hours each. It was 06.00 - 09.00, 09.00 - 12.00, 12.00 - 15.00 and 15.00 - 18.00. Linear regression equation was used with STATA version 15 program. Khon Kaen University. But on the other hand ozone has a positive correlation with nitrogen dioxide. And found that this linear equation can explain 81.29% relationships between variables (R² = 0.8129).
