Copper in Diatoms [PDF]

Nature, 1947
WORK undertaken in this Laboratory suggests that certain species of diatoms, which are the normal constituents of the slime film which forms upon a submerged surface in marine waters, contain copper, far in excess of the amount usually considered lethal for unicellular Algae.
