摘要
Results of neutron activation analysis (NAA) of Sargassum samples collected from the Qingdao Taipingjiao coast on March 20 , 1996 showed that (1) Sargassumthunbergii can to some extent potassium and calcium (the accumulation coefficientwas 10), (2) it can accumulate all trace elements , especially iron , manganese and zinc,(3) it can accumulate strontium , aluminium thorium , and rare earth elements.
