Abstract:

In order to investigate the impact of sediment in snow water on the soil ecological environment, the authors analyzed the particle composition, mineral composition, soluble ions and organic carbon which fromed sediment in snow water of Changchun, Baichen, Yanji, JiLin by X-ray diffraction, chemical methods. The results showed that the mainly particle size of sediment in snow water was <2 μm. The order of average content was: (<2 μm)>(>200 μm)>(20-200 μm)>(2-20 μm). The major primary mineral of sediment in snow water were quartz, feldspar, clay mineral composed by montmorillonite, illite, kaolinite, vermiculite. In atmospheric snow (SO42-+NO3-)/(Ca2++NH4+) was 1.38, with more strong neutrality to acid, it would not occur acid rain and would not impact on the environment. The organic carbon of sediment in snow water was higher, average content was 52.85 g/kg.
