Abstract

Sulfur dioxide (SO2) is one of the main air pollutants that has a significant impact on human health and the environment, especially in areas with intensive industrial, mining, and transportation activities. South Sumatra Province as one of the provinces with quite massive industrial and mining activities, is a strategic area to study the spatial dynamics of SO2 concentration. This study pioneers the use of Sentinel-5P satellite remote sensing for high resolution spatio analysis of sulfur dioxide (SO₂) at the provincial level in Indonesia. Focusing in South Sumatra from 2021–2024, we quantified SO₂ dynamics across 17 regencies/cities. Results identified significant concentration SO2 in urban and industrial areas such as Palembang, Prabumulih, and Muara Enim, while agrarian areas such as North Musi Rawas and South OKU showed lower and more stable concentrations. Analysis revealed clear seasonal patterns, with dry seasons exhibiting elevated concentrations due to reduced atmospheric dispersion, and further linked fluctuations to post-pandemic economic recovery and land-use changes. Our findings demonstrate the critical value of Sentinel-5P as a tool for actionable air quality governance in Indonesia and underscore the importance of complementing satellite data with ground measurements for robust environmental policy.

Abstract

Air pollution is one of the most pressing environmental issues, with direct impacts on human health and environmental quality. The increasing intensity of transportation activities, industrial operations, forest and land fires, and regional development in South Sumatra Province has increased the risk of air pollution, particularly from nitrogen dioxide (NO2) and sulfur dioxide (SO2). This study aims to analyze the concentrations and multi-year trends of NO2 and SO2 in South Sumatra based on passive sampler measurements conducted at 68 monitoring sites across 17 districts and municipalities during the period 2021–2024. The results show that the average concentrations of NO2 ranged from 6.654 to 9.944 micrograms per cubic meter, while SO2 concentrations ranged from 7.303 to 8.456 micrograms per cubic meter. All measured concentrations were below the National Ambient Air Quality Standards as well as the European Union guideline values. Trend analysis indicates a consistent decrease in NO2 and SO2 concentrations from 2021 to 2024. These findings contribute to the availability of long-term air quality data and enhance understanding of NO2 and SO2 dynamics, providing a scientific basis for the development of evidence-based strategies for air pollution control and prevention in South Sumatra Province. Keywords: nitrogen dioxide, sulfur dioxide, passive sampler, South Sumatra, air pollution trends.
