Precise quantitative analyses of arsenic for a small amount of dried plant samples (〜10 mg) by instrumental neutron activation analyses (INAA) and inductively coupled plasma-mass spectrometry (ICP-MS) were developed to evaluate environmental purification of soil and water by phytoremediation technique. To confirm the reliability of the analytical methods, we measured standard material NIES No.l (pepperbush). Obtained arsenic contents of the NIES No.l by INAA and ICP-MS were 2.18 ± 0.03 μg/g-DW and 2.25 ± 0.03 μg/g-DW, respectively. Both results agree well with the certificated value of the NIES standard (2.3 ± 0.3 μg/g-DW). Results by both analytical methods for the higher arsenic contents ofPteris vittata L. (〜4,000 μg/g) were also satisfied to confirm the accuracy. Consequently, we conclude that both quantitative analytical methods are appropriate for determine the wide range of arsenic content in small amount of plant samples.
