Arsenic chains synthesis

Many papers on biotransformation of arsenic via marine food chains have been published. For example, three trophic levels of marine organisms (phytoplankton Dunaliella marina zooplankton Anemia salina and shrimp Lysmata seticaudata) were tested for their arsenic metabolism [41]. The experimental results led to the conclusion that organic forms of arsenic in marine food webs were derived from in vivo synthesis by primary producers and were efficiently transferred along a marine food chain. The shrimp, the highest trophic level in this food chain, could not form organic arsenic by itself. In this case, arsenate taken up from water was converted largely to arsenite. Similar conclusions were obtained from experimental results on a phytoplankton-mussel...
