Abstract: Abnormal composition can, sometimes, be detected from the analytical results of geochemical samples.Based on those, the researcher could judge whether these samples have been contaminated or not by later pollution.Special experiments aimed at several key procedures responsible for polluting geochemical samples have been performed. The result shows that the geochemical samp les are very easy to be polluted during collection, package, transportation, pre-treatment and p reservation, etc. Owing to the similarity of some contaminations to real compositions of the analyzing samples, once polluted, it is very difficult to tell the difference between them and likely result in disturbance or even cover the real composition of those samples to mislead the research work and bring losses. Although some researchers are engaged in the specific study on this aspect, relative reports are seldom read, it seems still need more efforts to elucidate this process
