摘要：

A simplified food chain of phytoplankton species, Artemia sp., and Palaemonetes pugio was used to study pathways of arsenic uptake in estuarine ecosystems. Uptake of arsenic by phytoplankton was significant; however, only small amounts of arsenic were incorporated by Artemia and no significant increases in arsenic content of P. pugio were found in those organisms exposed to arsenic‐contaminated food or to elevated water concentrations.
