Description
Xiongyi Miao and co-authors measure rare earth elements building up in wild fish near Guangzhou, China. Their 2024 study found total levels from 1.32 to 67.74 micrograms per kilogram. Light rare earths dominated the mix. Chemical fingerprints showed an excess of one element and a near normal level of another. Fish sorted into high, medium, and low accumulation groups.
Bottom feeding fish held more light rare earths, pointing to the sediment as a source. All round feeders held more overall, with less sorting between light and heavy types. Fish under eighteen centimeters and 130 grams were most prone to build up these elements. Intake estimates stayed within the safe daily bound of seventy units. Even the highest risk group, children eating one local fish species, stayed under it. The authors conclude eating these fish poses no clear risk, while fingerprints trace how the elements move through food webs.
