Treffer: Simulation and prediction of soil contamination migration for organic compounds under multiple scenarios in coastal areas of Rizhao City, Shandong Province.

The environmental pollution issues caused by organic compounds have garnered widespread attention across all sectors of society. However, the integration of quantitative analysis and specific operational guidelines for organic compound pollution remains incomplete. The present study focuses on the prevention and control of organic compound pollution in soil, with a view to identifying key production areas and primary organic compound pollution sources, such as dichloromethane, toluene, and benzene, in the coastal areas of Rizhao. A dynamic numerical model for the transport of solutes in soil was established, with the HYDRUS 2D software utilized to address the spatiotemporal distribution patterns and soil risk thresholds of the three organic pollutants under three leakage scenarios: short-term leakage, continuous leakage, and periodic leakage. The applicability of the model under the three leakage scenarios was proposed, and a technical application system of "PA (Prediction Assessment)—EM (Emergency Measures)—RE (Repair Evaluation)" was established. The findings of this study provide technical support for the prevention, control, and remediation of soil pollution caused by organic compounds. [ABSTRACT FROM AUTHOR]
