| rapid determination of arsenic species in freshwater organisms from the arsenic-rich hayakawa river in japan using hplc-icp-ms. | speciation analyses of water-soluble arsenicals from freshwater and biological samples collected from the hayakawa river (kanagawa, japan), which contains a high concentration of arsenic, were performed using high performance liquid chromatography/inductively coupled plasma mass spectrometry (hplc-icp-ms). river water contained only arsenate, which is a pentavalent inorganic arsenical. the water bug stenopsyche marmorata contained inorganic arsenicals accounting for 77% of the water-soluble arse ... | 2009 | 19203781 |
