Evaluation of Air Pollution Standard Index for NO2 Parameter in Jakarta and Bogor

Abstract

Abstract One Indonesian Air Pollution Standard Index (ISPU) parameter is nitrogen dioxide (NO2), with a minimum concentration of 80 μg/Nm3 in ISPU 0-50. This research aim was to evaluate NO2 concentrations less than 80 μg/Nm3 in ambient air and determine the ISPU number based on NO2 concentration. This investigation was conducted from February until April 2021, utilising secondary information compilation and field estimations. The method of the NO2 concentration test was based on the national standard SNI 7119-2:2017. The run of NO2 concentrations obtained from checking the information in Jakarta and Bogor was 6-51 μg/Nm3, and from inspecting came about 17-40 μg/Nm3. NO2 concentrations from monitoring data and sampling were deficiently compared to the NO2 minimum concentration limit in ISPU. ISPU number for maximum NO2 concentration in Jakarta and Bogor was 32, relatively low than the ISPU NO2 minimum standard of 0-50. The relevant NO2 concentration limits as an initial indicator of ISPU 0-50 were 0-37 μg/Nm3, and for ISPU 51-100 were 38-68 μg/Nm3 based on the NO2 toxicity study. Based on the research findings, it can be concluded that the relevant concentration of NO2 for ISPU 0-50 is 0-37 μg/Nm3, whereas for ISPU 51-100 is 38-68 μg/Nm3.
