| Abstract: | With the wide use of rare earth,more and more rare earth accumulate in natural water,so the effect of rare earth on water environment has moved into the spotlight in bioinorganic chemistry of rare earth.This paper simulates water environment,under which lanthanum accumulates,to aim at studying the effect of lanthanum-accumulating environment on growth of alexandrium tamarense,which may excrete paralytic sellfish poisons.The result shows that the accumulation of lanthanum has an active effect on growth of alexandrium tamarense in dose dependent manners,moreover,the longer time algae grow,the more apparent the active effect is. |
