| Abstract: |
| The work aims to analyze the prediction and evaluation method of soil impact mainly based on atmospheric deposition. The dry deposition, wet deposition and total settlement of organic waste gas were calculated by AERMOD model. The dry deposition of toluene accounted for 97% to 99% of the total settlement in this area, and the contribution value of wet deposition to the total settlement was very small. The settlement speed range of toluene in the dry deposition process of this area was 0.0003~0.0033 m/s and the average settlement speed was 0.0016 m/s. The calculation of atmospheric deposition of organic waste gas represented by toluene is mainly based on dry deposition. The dry deposition rate has obvious diurnal variation characteristics, and generally the maximum value appears around noon. The atmospheric deposition has little impact on the surrounding soil environment. |
