Hyperaccumulation of Elements in Marine Organisms


Hyperaccumulation: Phenomenon that accumulates a specific element highly and selectively.
Hyperaccumulation level:
More than 100 times higher than the average of other species in the same location or 'Reference' plant and animal collected from natural background sites.
Uses: Indicators for monitoring marine pollution. Valuable samples for in vivo analysis and for studying physiological roles and accumulation mechanisms of metals.
(in case of land plants: Bioremediation, Phytomining, Mineral exploration, etc.)
Hyperaccumulators: Organisms that hyperaccumulate elements. Elements in animals are often localized in certain tissues or organs.


The followings are hyperaccumulators that I have discovered and am studying at present.
