Arsenic and antimony speciation in open-ocean waters

This project aims to understand arsenic and antimony speciation in the ocean. Both arsenic and antimony form methylated species, yet little is known how marine organisms produce these methylated species during metalloid detoxification. To better understand these detoxification pathways, we plan to grow marine phytoplankton to understand methylation processes and compare results to those obtained from phytoplankton collected at sea.
