영문 초록

Objectives: Most of the PM₁₀ in subway stations is spread by the train-induced wind from the tunnels. Therefore, in order to improve air quality in subway stations, it is important to remove the PM₁₀ from the tunnels. After the installation of PSD (platform screen doors), the influence of train-induced wind and PM₁₀ at the platform has decreased, but is estimated to have increased in subway tunnels. This study was conducted to investigate the control of PM₁₀ in subway tunnels by applying a 500-fold diluted solution mixed with a humectant using a natural polymer. Methods: For this purpose, we tested the dust reduction effect in a laboratory and corrosion test and water pollution using fish and aquatic plants for the natural dust collecting agent. In the tunnel of a subway station, we used the natural dust collecting agent over 15 days. The study was carried out on PM₁₀ control during operation, which accounts for more than 70% of subway dust. Results: As results, the natural dust collecting agent exhibited an excellent dust control effect, and it was safe for water quality and soil. It showed the effect of controlling PM₁₀ in the subway tunnel by 49.5- 64.7% over 15 days. The use of the dust collecting agent for the control of PM₁₀ could be confirmed in the subway. Conclusion: It is necessary to clearly explain the major portions of chemical components contained in PM₁₀ to figure out the characteristics of PM₁₀ and to develop effective reduction measures to decrease the adverse effects of PM₁₀ in the subway.
