“…Overall, emission of pollutants in metropolitan cities finds the largest sources of SO2 emission from the summer season 2019 to 2023 in 21 districts of Medan city (Figure 4). Sulfur dioxide (SO2), produced in natural or anthropogenic mechanisms, is decided as a pollutant point of reference by the Indonesian Air Pollutant Index (ISPU or API) owing to its adverse effects on public health and the environment (Commane & Schiferl, 2022;Liu et al, 2023). Monitoring SO2 concentrations is essential to track air quality, collect information continuously, and provide a consistent long-term database.…”

This study aims to monitor the impact of sulfur dioxide (SO2), a significant contributor to atmospheric corrosion and associated with air pollution, in urban and industrial areas through empirical models of spatial distribution and temporal estimation in Medan. Datasets of Sentinel 5P NRTI are worth using to monitor the formation of sulfate aerosols or SO2 emissions from natural sources and anthropogenic origin in near real-time from 2019 until 2023 on the local scale, Medan. The source dataset covers 1,11 km of spatial image resolution on orbital in daily revisit time with a spectral bound between the ultraviolet and the shortwave infrared. The measurement of atmospheric SO2 concentrations is generated by enumerating the SO2 vertical column density technique at the soil surface with the cloud-based platform The Earth Engine (EE) Code Editor to handle large data sizes and produce interactive mapping. Based on the availability of auxiliary results, the number of spreading SO2 concentrations fell from 0,92 mmol/m2 in 2019 to 0,41 mmol/m2 in 2023, a reduction of 49.98 percent. The average of SO2 concentrations has decreased substantially over the years. Consequently, these pollutants have recorded long-term health and meteorological parameters impact that substances can rise or reduce acid rain.Keywords: Air pollution, Meteorological parameters, Sentinel 5P NRTI, SO2

“…Once inhaled, it can react on moist membranes to form corrosive substances such as sulfurous acid, sulfuric acid, and sulfate, which have a significant impact on the human body. 2 Therefore, continuously improving SO 2 management capacity and effectively reducing its emissions are currently important tasks of China's air pollution control. 3 Among the traditional flue gas desulfurization (FGD) technologies, the limestone−gypsum method is the most widely used, in which limestone is the commonly used absorber, but this method can lead to secondary pollution due to the solid waste and wastewater of desulfurization, it requires a large investment, and its equipment is prone to corrosion and clogging.…”

In this paper, a diethylene glycol monomethyl ether (DGME) + dimethyl sulfoxide (DMSO) system was used for the absorption of dilute SO2, and the gas–liquid equilibrium (GLE) data of the binary system for SO2 at p = 123.15 kPa and T= (303.15 K-318.15 K) were measured by a GLE device. Meanwhile, different temperatures and different ratios were also measured, Henry’s constants at different temperatures were fitted based on the measured data, and the thermodynamic parameters of dissolution enthalpy, dissolution entropy, and dissolution Gibbs free energy of the dissolution process were calculated. The results of five cycles of SO2 absorption and resolution showed that the maximum absorption of SO2 in the binary system was 0.85 g/g. The desorption rate could reach 97%, and the absorption and desorption capacities did not decrease significantly after the cycle. The mechanism of SO2 absorption in the binary system was discussed and analyzed by combining spectral analysis and quantum chemistry. The spectroscopic results show that the weak interaction forces between DGME, DMSO, and SO2 are hydrogen bonding forces and dipole–dipole interaction forces, which lay the theoretical foundation for the application and practice of binary hybrid systems. This can provide important GLE data for the design and operation of organic solvent absorption and desorption of SO2 in flue gas desulfurization, and the prepared absorbent has a potential industrial application value.
