| 摘要： |
| 基于安徽郎溪大气干湿沉降物中Cd等8种重金属元素的沉降特征，评价研究区大气环境质量状况；通过估算1年后土壤中相应元素的含量变化，探讨大气干湿沉降物对土壤环境的影响程度。结果表明：研究区内大气干湿沉降物各元素年沉降通量差异显著，As、Cd、Hg沉降通量均处于较低水平，其中，Cd、Hg年沉降通量明显低于其他元素，Zn年均沉降通量在全区最高；区内大气环境质量相对较好，对土壤元素含量影响较弱，大部分元素含量年均增幅<0.10%，Cd增幅最高，达0.42%。 |

| Abstract: |
| Based on the deposition characteristics of eight heavy metal elements (including Cd) in dry and wet atmospheric deposition in Langxi County, Anhui Province, the atmospheric environmental quality of the study area is assessed. By estimating the consequent changes in the content of corresponding elements in soil after one year, the impact of atmospheric deposition on the soil environment is investigated. The results indicate significant variations in the annual deposition fluxes of different elements in the region. The fluxes of As, Cd, and Hg are all at low levels, with those of Cd and Hg being notably lower than the others. Zn exhibits the highest annual deposition flux in the study area. The atmospheric environmental quality is relatively good, and its impact on soil element content is limited. The estimated annual percentage increase in the content of most elements is below 0.10%, with Cd showing the highest increase of 0.42%. |
