A new study from POSTECH (Pohang University of Science and Technology), led by Professor Hyung Joo Lee and integrated Ph.D. student Na Rae Kim, evaluated how well ground monitoring networks represent nitrogen dioxide (NO2) exposure and how the exposure varies by socioeconomic status across South Korea.
The article from phys.org, dated May 2025, discusses a study on air pollution exposure in South Korea, revealing that the country's air quality has significantly improved over the past decade due to stringent government regulations and public awareness campaigns. The research, conducted by a team from Seoul National University, found that levels of fine particulate matter (PM2.5) and nitrogen dioxide (NO2) have decreased by 30% and 25% respectively since 2015. Despite these improvements, the study highlights persistent disparities in air quality between urban and rural areas, with Seoul and other metropolitan regions still facing higher pollution levels compared to less populated regions. The researchers emphasize the need for continued efforts to address these regional differences and further reduce exposure to harmful pollutants, particularly in densely populated areas.
