Abstract:
In this study, we simulated and predicted the accumulation of deicing agents in the soil and water system of the study area (a ski resort in Beijing, China) and discussed the environmental impact of deicing agents on the surrounding water system and soil under a standardized dosage. The widely used sodium chloride deicing agent was selected, and the standardized dosage of the deicing agent was estimated. Analysing the prediction results of the changes in chloride ion content in water systems and soils after the use of deicing agents from 2021 to 2029 leads to the conclusion that the use of deicing agents will increase the chloride ion content of the study area. It is predicted that chloride ion content in the water system and soil will increase year-by-year from 2021 to 2026, achieving a stable trend after 2027. It is concluded that the deicing agent has no obvious effect on the surrounding water body and soil under the standardized dosage. This research is intended to fill the gap in quantitative research on the environmental impact of deicing agents, to provide a reference and guidance for the engineering application of deicing agents, and to offer support for the improvement of deicing agent management measures.
