A moss clears arsenic from water

Warnstorfia fluitans removed up to 82% arsenic from water within an hour

As removal rate was highest at 1 μM As and no nutrients in the water

W. fluitans removes both arsenite and arsenate from water

Most accumulated As species were bounded in moss biomass tissue

Both dead and living moss can reduce As from water
