Utilization of synchrotron radiation based technique in the chemical analysis of environmental samples were reviewed. At first, the environmental samples were defined as follows, (1) elements contained in the samples are unknown, (2) chemical form of the elements are also unknown and (3) distribution of the chemical species are unknown. To elucidate these chemical state information, fluorescence X-ray analysis, fluorescence based XAFS and imaging XAFS technique were introduced by using some examples.
