Dimethylarsinate (DMA), Monomethylarsonate (MMA) and inorganic arsenic were determined in the extract of Pond Sediment CRM issued by the National Institute for Environmental Studies (Japan). After arsenic compounds were extracted from the sample with 1 M or 10 M hydrochloric acid, they were determined by flameless atomic absorption spectrometry coupled with solvent extraction and anion exchange chromatography. As a result, the contents of arsenic compounds which could be extracted from the sample with 1 M hydrochloric acid were (5.9±0.6) ppb for DMA, (8.4±0.7) ppb for MMA, and (219±18) ppb for inorganic arsenic, while those which could be extracted with 10 M hydrochloric acid were (5.8±1.0) ppb for DMA, (53.7±5.9) ppb for MMA, and (6.37 ±0.13) ppm for inorganic arsenic.
