Abstract:
Because the factor scores of the parallel factor analysis can represent the concentration of the various factors of every mixed sample, the method of parallel factor analysis can be used for source apportionment. But the factors were not the same as the source samples sometimes. In order to achieve source apportionment, a relationship between the mixed samples and the source samples of the three-dimensional fluorescence matrix was designed. The coefficients of the relationship came from the factor scores and represented the contribution ratio of the sources. The relationship can be used for source apportionment of pollutions in water environment. And the coefficients of the relationship represented the contribution ratio of pollutant sources.

Sampling Plans
Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...
