Abstract

Abstract

Fifteen rare earth elements (REEs) in benthic seaweeds, molluscs and arthropods(mainly crustaceans) from the Xiamen Bay and adjacent waters w ere determined with an inductively coupled plasma mass spectrometer (ICPMS) in order to study the REE distribution and their environmental implications.The results show that the total REE contents in seaweeds vary between 0.780~49.1μg/g and the highest REE content is found in green seaweeds with an average of 24.3μg/g.The contents of REE in molluscs are between 0.365~21.6μg/g and the bivalves show the higher REE content than gastropods, with an average of 12.9μg/g.The contents of REE in art hropods are relatively low and range from 0.154 to 0.807μg/g.Enrichment of light REE (LREE) over heavy REEs (HREE) was observed for all benthic or ganisms, which suggested higher biological effects of LREE than those of heavy REEs.The NASC-normalized distribution pattern of REE for most benthic or ganisms showed a W-type tetrad effect, while small differences were observed for different biological groups.The significance of taxonomic and geographic variation in contents and distribution patterns of REE in benthic or ganisms for ecological environmental monitoring was discussed.
