为研究区域大气降水中微量元素（Fe、Al、V、Cr、Mn、Ni、Cu、Zn、As、Se、Mo、Cd、Ba、Pb）的本底水平，对北京市五岳山52个雨水样品和73个总悬浮颗粒物（TSP）样品进行了分析。采用电感耦合等离子体质谱法（ICP-MS）分析了中国南部庐山的样品。结果表明，与国内外相比，目标区湿沉降和干沉降中的总蒸发量显著升高，雨水的容重平均pH值为4.43。湿沉积和干沉积的相对贡献的TE元素之间的差异显着。V、As、Cr、Se、Zn和Cd的湿沉降通量明显大于干沉降通量，而Mo、Cu、Ni、Mn和Al等污染元素的去除则以干沉降为主，干沉降通量之和是湿沉降通量之和的4倍。基于简单累积模型的预测结果发现，七种有毒元素的含量土壤中的铬、镍、铜、锌、砷、镉和铅等元素受年大气沉降的影响会迅速增加，增加量分别达到0.063、0.012、0.026、0.459、0.076、0.004和0.145 mg kg-1，分别此外，土壤中重金属含量的年增长率在0.05%（Cr、Ni）~ 2.08%（Cd）之间。大气沉降导致土壤中Cr和Cd的累积。Cd是大气沉降中潜在生态风险最大的关键元素。
To investigate the regional background trace element (TE) level in atmospheric deposition (dry and wet), TEs (Fe, Al, V, Cr, Mn, Ni, Cu, Zn, As, Se, Mo, Cd, Ba, and Pb) in 52 rainwater samples and 73 total suspended particles (TSP) samples collected in Mt. Lushan, Southern China, were analyzed using inductively coupled plasma-mass spectrometry (ICP-MS). The results showed that TEs in wet and dry deposition of the target area were significantly elevated compared within and outside China and the volume weight mean pH of rainwater was 4.43. The relative contributions of wet and dry depositions of TEs vary significantly among elements. The wet deposition fluxes of V, As, Cr, Se, Zn, and Cd exceeded considerably their dry deposition fluxes while dry deposition dominated the removal of pollution elements such as Mo, Cu, Ni, Mn, and Al. The summed dry deposition flux was four times higher than the summed wet deposition flux. Prediction results based on a simple accumulation model found that the content of seven toxic elements (Cr, Ni, Cu, Zn, As, Cd, and Pb) in soils could increase rapidly due to the impact of annual atmospheric deposition, and the increasing amounts of them reached 0.063, 0.012, 0.026, 0.459, 0.076, 0.004, and 0.145 mg kg−1, respectively. In addition, the annual increasing rates ranged from 0.05% (Cr and Ni) to 2.08% (Cd). It was also predicted that atmospheric deposition induced the accumulation of Cr and Cd in surface soils. Cd was the critical element with the greatest potential ecological risk among all the elements in atmospheric deposition.
