Application and Study on Analytical Methods for Trace Elements in Soil and the Review of Certification of Environmental and Geochemical Soil Standard Samples

Trace element analyse in soil is important. But it is prerequisite that the research of analytical methods and the method's feasibility or applicability. Using the analytical methods for 1:200 000 geochemical exploration, which effective and ripe determined and certified 8 Geochemical Soil Standard Reference Samples(GSS1-8). And, entrusted by China Environmental Monitoring General Station, 4 Environmental Soil Standard Samples(ESS1-4) which national grade were determined and certified. The analytical methods are proved exactly and credible by data and it can be popularized.
