A fast screening method for determination of inorganic arsenic in marine samples was developed. This method is based on selective
hydride generationanddetectionby inductively coupled plasmamass spectrometry. Using a high concentration of hydrochloric acid
together with hydrogen peroxide for hydride generation leads to selective conversion of inorganic arsenic species into arsane. The
accuracy of this method was verified by comparative analyse by high performance liquid chromatography coupled with hydride generationandatomic
fluorescence detection.
