Extraction and detection of organoarsenic feed additives and common arsenic species in environmental matrices by HPLC-ICP-MS

► Organoarsenic compounds are widely used as feed additives to animals. ► Unmetabolized organoarsenic feed additives are released into the environment. ► A method was developed to measure these additives and environmental arsenic species. ► Conditions for extracting these As compounds from soils and sediments were optimized. ► The method can help study the environmental distribution and fate of these additives.
