Industrial complexes near cities release significant air pollutants, impacting residents. Advanced remote sensing and in situ techniques revealed higher emissions than official reports, necessitating better air quality monitoring and mitigation strategies.
Area of Science:
- Environmental Science
- Atmospheric Chemistry
- Industrial Ecology
Background:
- Industrialization leads to air pollution near urban areas, affecting resident health.
- Accurate air quality monitoring is crucial for public health and environmental protection.
Purpose of the Study:
- To estimate pollutant emission flux from the Sinpyeong Jangrim Industrial Complex.
- To assess pollutant dispersion to nearby residential areas.
- To compare emission estimates with official Pollutant Release and Transfer Registers (PRTRs).
Main Methods:
- Utilized mobile laboratory with Solar Occultation Flux (SOF), Sky Differential Optical Absorption Spectroscopy (SkyDOAS), and mobile extraction Fourier Transform Infrared Spectrometry (MeFTIR).
- Employed the HYbrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model for pollutant dispersion simulation.
- Quantified emission fluxes of total alkanes, SO2, NO2, HCHO, and CH4.
Main Results:
- Total alkanes showed the highest average daily emission flux in zones S1 and S2.
- HYSPLIT confirmed elevated pollution in downwind residential areas, influenced by wind patterns.
- Estimated total annual emission fluxes were significantly higher (24.3 and 4.9 times) than PRTRs data.
Conclusions:
- Advanced remote sensing and in situ techniques provide more accurate air pollution emission data.
- Existing PRTRs significantly underestimate industrial air pollution, especially from small businesses.
- Targeted interventions are needed to mitigate air pollution in downwind residential areas.
