- 摘要：利用ICPAES、ICPMS、IC测定法,测定了北极地区不同纬度的17个雪样品的化学成分。结果显示,在被测试的32种化学成分中,14种化学成分被检测出。用富集因子法判断了雪中化学成分的4种可能发生源,即人为活动源、地壳源、海洋源和混合源。计算S/Na比值发现SO42-、NO3-主要来自人为活动源.
- Abstract：Seventeen snow samples were collected during Aprilto May 1995 in different Arcticregions, and the chemicalconstitutents were measured by three methods, Inductively Coupled Plasma Emission Spectroscopy (ICP AES), Inductively Coupled Plasma Mass Spectroscopy(ICP MS), and Ion Chromato graphy(IC).Fourteen chemicalconstituents were detectedamongall measuredones.The enrichmentfac tor method was used to determine the possible originan thropogenic, curst, oceanic, and mixingorigins, of chemical constitutentsinsnow. The S/Na valuas suggestthatSO42-, and NO3- are mainlyfrom anthro pogenicactivities.
