Abstract
This study aims to analyze and map the concentration of ozone gas in ambient air in Padang City. The study was conducted by taking samples of ozone gas at 52 points in Padang City for one hour of measurement. Ozone concentration was analyzed by NBKI method using a spectrophotometer. From the results obtained, the concentration of ozone gas at Padang City varied between 6.32 and 87.06μg/Nm3 at an average concentration of 25.67μg/Nm3. This condition is still below the quality standards set by Goverment Regulation of Indonesian Republic Number 41-1999 amounted to 235μg/Nm3. Factors affecting the amount of ozone gas concentration are transportation factors and meteorological factors. The most influential Meteorological factor is the air temperature. Mapping the concentration of ozone gas in Padang City by using Surfer 10 illustrates that an area with the highest ozone gas concentration range is in the North, Northwest and Southern area of Padang City. The highest ozone gas concentration range of 65-90μg/Nm3 is in the southern which is in Kecamatan Lubuk Begalung and the lowest ozone gas concentration was located in the East and Northeast which is in Kecamatan Lubuk Kilangan and Kecamatan Pauh with a concentration range of 5-20μg/Nm3.
